Toshinori Yagi/Synopsis

History
Toshinori was born Quirkless during a time in the world where evil ran rampant due to the influence of All For One. Crime rates were on the rise because citizens had no hero to believe in. This inspired the boy to become a powerful hero who could provide hope for innocents and defeat evil.

During his teenage years, Toshinori met a pro-Hero named Nana Shimura and explained his ideals to her. He told Nana that he wanted to create a world where everyone can smile and live happily together. For that to happen, the world needed a "Symbol of Peace" to inspire a new age of harmony. Toshinori believed he could become the pillar that inspires people everywhere. Nana believed the Quirkless boy and took him as her apprentice. She trained Toshinori and passed One For All down to him, making him the eighth torchbearer of the great power. Toshinori went on to wield the power for forty years.

Toshinori attended U.A. High School, where Nana's friend, Gran Torino, served as his homeroom teacher and trained him. Toshinori's body was strong enough to utilize One For All at 100% from the start of training, so Gran Torino mainly focused on teaching Toshinori how to properly fight, although his training methods were so harsh that he accidentally instilling an innate fear within him.

All Might Rising
Inheriting One For All comes with the danger of facing All For One. Eventually, Toshinori, Nana and Gran Torino faced All For One, but the villain was too powerful. Nana sacrificed herself so that Toshinori could live on, entrusting his safety to Gran Torino. Toshinori could only watch as his master gave her life against All For One's supreme evil.

As a promise to his close friend Nana, Gran Torino continued training Toshinori in her place. However, Toshinori was distraught after the death of his master and was unable to train to his potential. Thoughts of revenge plagued Toshinori's mind and he wished to avenge Nana, who he saw as a true hero. Gran Torino reminded Toshinori that his enemy is a man who's walked the earth for over a hundred years. Toshinori cried while saying his master gave up everything to raise One For All's next torchbearer and admits he thought of her as his own mother.

Gran Torino recommended him to train in the United States after he graduated so All For One could not reach him and to gain experience as a hero. He reminded Toshinori why Nana sacrificed herself and restored his resolve. That spring, Toshinori graduated from U.A. and prepared to cross the ocean. Before he departed, Toshinori reminded himself of his master's trademark smile. He shaped his hair and donned what would become his own signature smile for the first time as All Might.

All Might in America
Soon after moving to Los Angeles, California, Toshinori rescued a group of scientists from an explosion. One of these upcoming student scientists was David Shield. David thanked Toshinori and noticed his destroyed attire. He developed a sturdy hero costume that would come to be known as All Might's young age costume. Toshinori and David would quickly become best friends and acted as a hero team throughout California.

Toshinori shared his dreams with David. He told him that he desired to become a Symbol of Peace and shine a light on the world. Together they took down a pair of L.A. Villains and David even relayed All Might's message to everyone watching, truly believing that one day All Might would become the world's top hero. Eventually, he met Melissa Shield, David's daughter, who was born Quirkless. Over time, All Might would serve as an uncle figure to Melissa. He encouraged her to become a support engineer in order to help other people, just like her father.

Return to Japan
Eventually, Toshinori returned to Japan and his meteoric rise would only continue through the Bronze, Silver, and Golden ages of his career. Eventually becoming the world's Symbol of Peace and No. 1 Hero. All Might reached the pinnacle dreams and inspired a new age of Pro Heroes where the country finally knew peace. Japan's crime rate dropped down to below 6% because of All Might's presence, issuing in an era of peace. However, the looming threat of All For One was still present.

At some point he met Mirai Sasaki, a huge fan of him who wanted to be his sidekick. At first, Toshinori refused due to his policy of not taking anyone. However, Mirai was so persistent that All Might eventually let him be his sidekick, under the name of Sir Nighteye. Thanks to his ability to see the future, Sir Nighteye would act as the brains of All Might's operations while the No. 1 Hero was operating at the peak of his career. For many years their partnership worked well, even Toshinori revealed the truth about One For All to his him.

The Underground Masquerade
All Might returned to the Might Tower after spending three days resolving consecutive incidents, setting a new record. After thanking the reporters and journalists gathered there for their encouragement and congratulations, All Might retired behind the Might Gate to rest. Before going to sleep, Toshinori asked Sir Nighteye for any last minute job, but his sidekick told him his priority should be resting after going 72 hours working non-stop. Just then, they received an emergency dispatch from Osaka after the Might Signal was activated. Sir Nighteye wanted to check first if local heroes can take care of the situation first, but All Might transformed into his muscular form and and blasted off, knowing Osaka's calling for him personally.

The reason for that emergency was caused by All For One, who in his desire to steal the Quirk Overclock from the hero O'Clock, had transformed several people into a violent mob that was rampaging through the city. Once he arrived to Osaka, and in the blink of an eye, All Might defeated all the villains. Then, after being informed of the situation, he goes to the place where the crowd emerged, but when he arrived all trace of All For One had disappeared, with only O'Clock and a couple of his allies at the scene.

After fixing the situation, the citizens of Osaka rejoice as All Might tops a new record in defeating nearly one hundred villains in one fell swoop, as well as assisting in many aspects of the clean up, before leaping off and heading back home for a proper rest.

The beginning of the end of All Might
Eventually, destiny caught up with him, and once again, All Might was brought face to face with All For One. The Symbol of Peace became the first torchbearer to defeat All For One, completely crushing his head and severely damaging the rest of his body. This was at the cost of critical injuries, as All Might's stomach was lost and his respiratory system was damaged beyond repair. This created a limit on how long All Might could use One For All, reducing his ability to be the Symbol of Peace.

Due to his injures and condition, Sir Nighteye pleaded with All Might to retire, as he didn't want All Might to push himself to the brink of death, but he refused. Nezu agreed with Sir Nighteye and told All Might that he could look for a successor of One For All in U.A., an idea that Sir Nighteye considered as the best option. Toshinori agreed that the Symbol of Peace would need a successor but refused to step down in case any new villains stepped up.

All Might asked who the Symbol of Peace would be until he finds that successor. Even though All For One was gone, another villain like him will eventually appear. Sir Nighteye threatened to stop helping should All Might continue his reign as the No. 1 Hero. He even uses his Foresight Quirk to warn All Might of his impending death. He told him that in six to seven years, he will confront a villain and head towards a gruesome death. All Might ignored Nighteye's warning and they dissolved their partnership completely.

In order to raise a proper successor, All Might enlisted himself as a teacher at U.A. High five years later. He spoke with Nezu about a potential replacement, and the principal believed that Mirio Togata, one of U.A.'s students, would make a fitting successor to One For All.

Vigilantes Beginnings Arc
During the period between when he defeated All For One until he became a professor at U.A., Toshinori was involved in a series of events caused by a criminal organization known as the Villain Factory, whose goals were unknown. For several weeks, the Villain Factory was dedicated to distributing through Naruhata streets a drug known as Trigger, an illegal substance that boosts Quirks but turns its consumers in violent Instant Villains, causing several incidents.

One day, one of the Factory's agents, Kuin Hachisuka, uses her Queen Bee Quirk to inject the drug into innocent civilians, turning them into a horde of Instant Villains, causing chaos at the streets. Suddenly, All Might and several other heroes such as Air Jet, Ingenium, Endeavor, Midnight, Eraser Head, and several others, appear and in a short space of time, they suppress all the Instant Villains.

Due to the villain outbreak, where several innocent people were turned into Instant Villains, detective Eizo Tanuma organized a meeting in the Police Station with several of the heroes who helped to stop the outbreak to discuss the situation and the best action to take. Because All Might could not attend, Eizo sent his partner Naomasa Tsukauchi to the Might Tower to request All Might's help in dealing with the Trigger outbreak, specifically telling him to talk to his secretary-manager, Toshinori Yagi.

On the top floor, the receptionist tells Naomasa that All Might will be returning shortly from Hokkaido. The Might Tower's roof opens up and All Might lands down. Many reporters ask All Might questions about global affairs. However, All Might apologizes and decides to leave office affairs to his staff; All Might retreats behind the Might Gate, which is only accessible to All Might himself.

Naomasa couldn't talk to All Might but went to the receptionist to ask for Mr. Yagi. Coincidentally, Toshinori Yagi (All Might in his true form) is by the receptionists as well and hears Naomasa's request. Toshinori and Naomasa chat in Might Tower cafe, with Toshinori introducing himself as Might's Productions Second Secretarial Office and that he handles All Might's private affairs. Naomasa explains the Instant Villains rampages that have been happening recently, to which Toshinori suggests that heroes should be more cautious going forward.

However, while they are having a conversation, Toshinori constantly makes excuses and runs to perform quick deeds as All Might. In the end, Toshinori accidentally returns with the uniform still visible, revealing his dual identity as All Might.

Toshinori asks Naomasa to keep his identity a secret, to which Naomasa replies that he will, but he tells Toshinori that the Police Force is troubled by his spontaneous acts of heroism and calls him out on not filing reports on all of his heroic activities, as customary of a Professional Hero. Toshinori is well aware that he must follow standard procedures when heroes wield their powers, but he wants to help people without being burdened by unnecessary procedures. While Naomasa understands him, he tells that every hero must follow the rules, and it would be a bad example if people know that the Number One Hero neglects his Hero duties.

Taking pity on All Might, Naomasa offers to file the reports himself, letting All Might act without any worries apart from telling him about his unplanned Hero activities. Toshinori is delighted with Naomasa's offer and accepts it, exchanging his personal contact number with him. The next day, Naomasa receives several cases of All Might's unplanned Heroics and wonders if it was Eizo's plan to push All Might's ordeal onto him from the start.

Sky Egg Arc
After this, Toshinori and Naomasa become friends, and for the next months, they have several meetings to keep themselves informed of their mutual jobs, with All Might carrying out his hero duties and Naomasa continuing with the police investigation to stop the traffic of Trigger and the Villain Factory. One day, after resolving a series of incidents in Okinawa, Toshinori Yagi returns to the Might Tower for a meeting with Naomasa in the building's cafeteria, only to find out the detective has his arm in a sling and several fractures. Naomasa explains to him that his injuries are the result of a confrontation he had against Number 6.

Although he tries to not give importance to his injuries, Toshinori is worried and tells him that if he had known, he would have come to help him. The detective replies that his public figure, All Might, can't be taking jobs for personal reasons, and can't prioritize saving certain people because they could be taken hostage or used as a diversion by villains. Toshinori can not deny that he is right.

With the start of a new year, detective Naomasa and Toshinori have another meeting, in which they say they hope to continue working together another year. Naomasa informs him that recently they have obtained new and important information about the case he is investigating. All Might offers to help him but, although he is grateful, Naomasa tells him that it is not possible.

Police investigations lead Naomasa to discover the place where the Villain Factory carries out its illegal experiments. A police raid takes place, but Number 6, the same villain who left Naomasa badly wounded the previous time, is there, and he blows up the place before escaping with five creatures called Bombers, in order to attack the Tokyo Sky Egg and kill Captain Celebrity. Luckily, Naomasa survives, and in a police helicopter, he goes to the Tokyo Sky Egg, where he sees several heroes fighting the Bombers. The hero Eraser Head is with him and asks him to call All Might to come to the place to help because although it seems that the heroes are winning, the threat is not over yet.

Naomasa agrees to Aizawa's request and calls All Might, who at that time is in a meeting at the Might Tower as Yagi Toshinori. Upon hearing Naomasa's call, Yagi apologizes and goes to a secluded area to talk to him. Naomasa tells him that the Tokyo Sky Egg is in trouble, but before he can clarify the situation, Yagi hears an explosion on the phone. Seeing how his creatures were being defeated, Number 6 had ordered the last one to self-destruct in a powerful explosion, which caused the Tokyo Sky Egg to begin to collapse, with thousands of people inside.

Upon hearing the explosion and Naomasa's request for help, the number one hero immediately leaves the Might Tower, taking him only a few seconds to reach the place and, in a flash, he smashes the remains of the tower out of the way, flattens the ground, brings animals to safety and lands the Tokyo Sky Egg dome safely, saving everyone. The bystanders are stunned by that inhuman feat and start cheering for All Might.

The media reports the Bombers' attack on the Tokyo Sky Egg, while hosting a large-scale event with some of the most famous heroes, and how All Might saved everyone from the disaster when the tower began to fall. Journalists and reporters ask All Might about his opinion. He simply thanks that there are no fatalities, and praise the efforts of the Pro Heroes, law enforcement and relief workers to care for the victims. After his statement, he says goodbye and runs away, being pursued by the media. After eluding them, All Might, now as Yagi Toshinori, returns to the place and meets secretly with Naomasa. He tells him that he's going to stick around for a while in case there's another attack.

Naomasa apologizes for getting bent out of shape, but Yagi tells him that it's fine and that it was his impassioned plea that got him there in time. Yagi explains to Naomasa that his Quirk has a strong psychological component to his strength. When he hears a plea for help, he feels it like a direct order to All Might. He tells him that when he accepted his power in order to save everyone and give them hope.

Naomasa feels confused about how he "accepted" his power, and All Might realizes that he has unwittingly revealed an important fact regarding One For All and its secrets. Before their conversation continues, they are interrupted by Shota Aizawa, Fat Gum and Monika Kaniyashiki, and Naomasa introduces them to Toshinori, who thinks that one of these days he will have to explain Naomasa everything about the secret behind All Might.

In the distance, at the top of a building, Number 6 watches the whole scene, still furious that All Might ruined his plans. However, he does not give up. and uses a device again to reactivate the Bombers' remains. The busted Bombers' pieces and bits start to regenerate, combine and grow into a gigantic and uniform mass of flesh that bursts releasing a swarm of two hundred mini Bombers to attack everyone, in his last attempt to cause a tragedy. Number 6 is confident that even All Might will not be able to destroy all the creatures, so he is sure that this attack will cause some deaths.

Everyone is surprised at this sudden attack, but it generates the appropriate distraction for Yagi to transform back into All Might, destroying the entire swarm with his Nebraska Smash, saving thousands of lives again. Number 6 can not believe what he just saw.

Naruhata Lockdown Arc
Several years have passed since the Sky Egg bombing. At that time, the villain Number 6 attentive against the life of Koichi, Kazuho and several heroes. He failed, and swore to Koichi that he would take revenge on him, starting with murdering Kazuho, who was hospitalized. The police and several heroes decide to help and protect Koichi and Kazuho.

A few days later, as promised, Number 6 decides to carry out his threat, and to do so, he first causes a blackout in Naruhata, cutting off all communications and causing all series of riots with the Anonymous to keep the heroes busy. He then storms the hospital, but Koichi and his allies force him to flee. With communications cut off, Naomasa asks Koichi to leave Naruhata and summon All Might, while they take care of the rest, but in the end Koichi decides to stay to face Number 6.

Meanwhile, in the cafeteria of the Might Tower, Toshinori is relaxing, eating his meal, and received the news broadcast talking about the Naruhata crisis. Toshinori hopes Naomasa’s job doesn’t get delayed due to the chaos. At that moment, he receives a phone call asking him to contact All Might to stop a Namahage attack in Akita. Toshinori decides to leave and tells the waiter not to clear his plate since he will come back. Once the problem in Akita is solved, Toshinori returns to the cafeteria to finish his dinner, but he is called again to request All Might to solve another problem in Tokushima.

Entrance Exam Arc
All Might spots the Sludge Villain fleeing after robbing a bank while he was getting groceries. He tracks the villain through the sewers and eventually finds him trying the seize the body of a young man, Izuku Midoriya. All Might uses his Texas Smash to blast the villain apart and saves Izuku. While the young man recovers, All Might encases the villain inside a couple of empty bottles, in order to take him to the authorities. When Izuku awakens, he finds that All Might has signed his Hero Analysis for the Future notebook and thanks him profusely.

All Might prepares to leave, but the young fanboy holds on to All Might after he leaps high into the air. At first, All Might tries to shake him off but stops after agreeing that Izuku would die if he dropped him in mid-air. He is forced to land and tries to leave again, but Izuku questions him on whether he can become a hero without a Quirk. Before answering, All Might's time in his muscle form comes to an end and he reverts to his true form, shocking Izuku.

All Might reveals to the surprised young man that he was injured in battle five years ago and can only stay in his hero form for a short time. He goes on to tell Izuku that professionals must always put their lives at stake to save the day and thus cannot openly say whether it is possible to be a Hero without a Quirk as it may not be possible. All Might says that if Izuku cares about saving people, he can always go on to become a policeman, as in that way he can be responsible for putting the villains in jail (even though it is often ridiculed). He tells Izuku that it is not bad to dream, but warns him not to obscure the facts and then leaves.

After leaving, All Might notices that he wasted time in talking with the young man, giving the villain he defeated a chance to escape, ridiculing himself for making a rookie mistake. He makes his way to the scene of the crime, where the villain has captured yet another young man, Katsuki Bakugo. He is unable to intervene after using up his hero form, but after seeing Izuku's bravery in trying to save Katsuki from the villain, while the heroes are unable to do anything All Might is inspired enough to step in and use Detroit Smash to defeat the villain, saving both Izuku and Katsuki. All Might is swarmed by reporters after the battle.

Later on that same day, All Might appears before Izuku, thanking him and giving him a proposal. All Might tells Izuku that he was touched by his bravery for trying to save someone, despite not having a Quirk, and tells him that he too can become a hero.

All Might reveals to Izuku that his Quirk can be passed down and that he has chosen Izuku to be the next one to inherit his Quirk. Izuku is shocked and asks why he would give someone like him his Quirk, to which All Might responds that he has been searching for a successor for a long time and now has found someone to whom he does not mind giving his Quirk, saying that despite not having a Quirk, Izuku tried to save Katsuki while other people and heroes stood idly by. Izuku accepts All Might's proposal and they begin training for the next ten months, explaining to him that in order for him to inherit his Quirk, Izuku's body (vessel) must be strengthened to the point of being able to handle the One For All's power.

After taking the decision to train Izuku to be the new One For All's successor, Toshinori phones Nighteye to tell him this, but Nighteye is vehemently against the idea that a Quirkless boy becoming the successor. Toshinori and Nighteye argue over the phone regarding Izuku; Toshinori argues that Izuku was intent on saving others while Nighteye argues that intentions were not good enough since there are more capable candidates with the same intentions as Izuku. However, Toshinori states that Izuku is Quirkless which made him a befitting candidate over the others.

All Might trains Izuku at the Takoba Municipal Beach Park, a coastline that has been filled with trash. He has Izuku clean up all the trash as part of training his body to become strong enough to withstand the power of his Quirk, otherwise, it can result in Izuku losing limbs. After 10 months have passed, Izuku surprises All Might by cleaning the whole beach and becomes a genuine vessel. Amazed by his feat, All Might rewards Izuku for his hard work by having Izuku consume a piece of his hair, enough DNA to transfer One For All to Izuku.

All Might takes part in viewing the U.A. Entrance Exam. He is pleased to see that Izuku used his Quirk and his willingness to sacrifice himself to save Ochaco Uraraka. After the exam finishes, All Might finalizes the paperwork to become a U.A. faculty member. He delivers Izuku's test results via holographic video. He first apologizes for not speaking to Izuku in the week after the exam. He continues, telling Izuku he did fine on the written exam and got zero combat points during the practical. However, he goes on to explain that Izuku's brave actions during the exam were enough to score him sixty rescue points, giving him more than enough points to get accepted into U.A.

Quirk Apprehension Test Arc
All Might is seen secretly inspecting Izuku's participation in the pitch trial of the Quirk Apprehension Test, impressed with Izuku's focus of One For All at the tip of his finger and for his quick thinking of using the Quirk in the shortest time possible at the last moment as a workaround for not being adjusted to the Quirk. All Might approaches Shota, calling him a liar and says that he saw that he once expelled an entire new class of first-graders last year. All Might knows that he kicks students out with zero chances, finding it weird that he did not expel Izuku on the spot and concludes to him that even he felt Izuku's raw potential.

However, Shota replies that Izuku's are above the "zero" mark and that is all. He continues to say that he can kick out anyone whose chances drop below that mark at any time. All Might then says that they will never get along. All Might later appears as the teacher of the Foundational Hero Studies class, saying that they will have a battle of trial for the period. He tells his students that U.A. has prepared their hero costumes and says to them to get changed into their costumes for the Battle Trial.

Battle Trial Arc
All Might complimented the costumes of his students before he noticed the similarities to his image in Izuku's costume and was internally annoyed by it. He soon explains to his students that they will be separated into Heroes and Villains for the Battle Trial and it will be a two on two team battle. He explains that in the Battle Trial, the villains will guard a nuclear weapon they intend on deploying and the heroes must stop them. He goes on to further say that the heroes can win by capturing the villains or reach the nuclear bomb before time runs out and the villains can win by capturing the heroes or keeping the core away from the heroes before time runs out.

All Might then decides that the teammates and pairs will be chosen by lottery. After the lottery, All Might draws from the boxes and says that the pairs that will do battle are the heroes Izuku and Ochaco versus the villains Katsuki and Tenya Ida. He explains that the villains will go in the building first, and then after five minutes, the heroes will go in. He tells them to go all out as it is a practical exercise, although he says that he will stop the Battle Trial if things get out of hand. All Might is seen in the surveillance room, saying to himself that Izuku will not get any special treatment from him and will grade him as harshly as the rest.

While watching Izuku and Katsuki battle, All Might is impressed by Izuku knocking down Katsuki and is revealed to have read Izuku's Hero Analysis for the Future notebook in their first meeting and recognizes that the boy has memorized Katsuki's moves and used it to his advantage. All Might soon tells Katsuki to stop after seeing what his hero costume can do to amplify his Quirk and becomes worried for Izuku after Katsuki initiates a huge explosion.

All Might then tells Katsuki that if he uses another huge explosion, he will end the Battle Trial and he will lose, reprimanding him for trying to destroy the building that protects their stronghold (the core) calling it foolish. Although he feels that he should stop the Battle Trial, he thinks that it would be better for Izuku and Katsuki to continue battling as it is necessary for the future that they envision themselves. After being asked to stop the Battle Trial, All Might is about to suspend it, but after hearing Izuku call out to Ochaco, he stops. After Ochaco touches the core, All Might announces that the Hero team wins.

All Might approaches Katsuki, telling him that it is time for his critique. He tells Katsuki that it does not matter whether he won or lost, but that he takes one look back, reflect on his experience and move on with life. In the monitor room, All Might says that Tenya Ida was the best during the Battle Trial. After being asked why he questions his students as to why he chose Tenya. After Momo Yaoyorozu gives her answer, he is shocked by her accurate deductions and nervously gives a thumbs up to her for being absolutely correct.

During the next Battle Trial, All Might is impressed by Shoto Todoroki for not getting his comrade caught in the attack and at the same weakened his opponents' positions as well as refrained from damaging the core. After everyone participates in the Battle Trial, he tells everyone that they did well and instructs them to change clothes and head back to class. Although he wanted to give Katsuki counseling for his self-confidence, he realizes that his transformation is running out of time and head to the nurse's office.

He is reprimanded by Recovery Girl for indulging his disciple, Izuku, too much and he says that he has nothing in his defense. They talk quietly, with him saying that his Quirk is secretly known by a selected few (including her). Chiyo asks if it is important to be a "Natural Born Hero" or "The Symbol of Peace" to which he replies that without such a symbol, the society of superhumans would fall to evil. She then tells All Might to be a better guide to Izuku.

Later, Izuku tells Katsuki that he obtained his Quirk from someone else but the latter does not believe it. All Might then appears before Katsuki, trying to counsel him on self-confidence, although he is told in response by Katsuki that he will surpass him as well, thus All Might decides to leave Katsuki alone, finding that teaching can be difficult.

U.S.J. Arc
While heading to the U.A. All Might sees Kamui Woods and Mt. Lady fighting the villain Habit Headgear, who had a family as hostages. All Might intervenes and uses Missouri Smash on Habit Headgear, defeating him and saving the family in the process. He then realizes that his Quirk is steadily dropping off, as the amount of time he can keep his Quirk activated has decreased.

In a flashback, Izuku is seen speaking to All Might telling him that he revealed to Katsuki about the secret of the One For All Quirk. However, All Might is not angry about it since Katsuki interpreted it as nonsense and tells Izuku to keep the secret to himself and no one else since if the villains knew about his secret, all of them would probably want to steal his Quirk.

He then tells Thirteen that he will not be able to appear at the Unforeseen Simulation Joint due to him using his Quirk too much and then takes a nap. After his nap, All Might tries to contact, Thirteen and Shota, but to no avail. He decides to go to the U.S.J, but Nezu arrives to have a discussion with him, being held up by Mr. Principal's endless talking, seeing that he has not changed either.

Unknowingly, the U.S.J. is attacked by a group of criminals who call themselves the League of Villains. The students are dispersed and Eraser Head and Thirteen are badly hurt when facing the villains. All Might then appears at the U.S.J, telling everyone to have no fear as he is there.

He says that he ran into Tenya and knows the gist about the situation. All Might quickly dispatches the villains in front of Shota, apologizes to him and picks him up. He then rescues Izuku, Minoru Mineta, and Tsuyu Asui. All Might asks the three to head to the entrance and leaves Shota with them. When Izuku tries to dissuade him into fighting, All Might tells him it is all right. All Might prepares to face the main people in charge of the attack: Tomura Shigaraki, Kurogiri, and Nomu.

All Might uses Carolina Smash on Nomu but has little effect. He realizes that his blows are not having any effect against the villain. After hearing Tomura Shigaraki's information on Nomu, All Might uses a backdrop slam against Nomu, causing an explosion. However, Kurogiri opens a gate with his Quirk, causing All Might's attack to fail and allows Nomu to grab All Might. However, the combined efforts of Katsuki and Shoto allow him to escape from Nomu.

All Might then blocks a punch from the regenerated Nomu, giving Katsuki some time to evade. All Might then calls Tomura's view on the title Symbol of Peace as rubbish. He then tells the children to escape, thanking Izuku for his concern and says that he is fine. Realizing that he has only a little time left, All Might decides to go all out. He and Nomu get into a fistfight and All Might sees that he can absorb each punch at 100%.

All Might decides to surpass his 100% and launches a devastating punch against Nomu, sending Nomu flying out of the U.S.J, defeating him. In his younger ages, All Might claims that it would have taken five punches top to defeat someone like Nomu but now that he is not in his prime self anymore, it took over 300 punches. Even though he is badly beaten and battered, All Might prepares to fight Tomura.

All Might asks why he is not going to fight since it is his mission to kill him. All Might then realizes that his fight with Nomu has completely left him powerless, not even having the strength to take another step. Tomura and Kurogiri attack All Might, but Izuku intervenes to protect the powerless All Might. However, one of the heroes that Tenya called as backup stops Kurogiri and Tomura from attacking him.

All Might then goes back to his normal form as Eijiro Kirishima approaches him and Izuku, he gets worried that his secret would be exposed but Ken Ishiyama arrives and blocks Eijiro's way before he discovers All Might's weak form. Cementoss tells All Might that he was told about his state and that his secret is safe, to his relief and gratitude. When Izuku says he could not do anything, All Might says it is not true, telling him that if it were not for his few seconds of bravery, he would be dead and thanks him for saving him.

All Might is then seen at U.A.'s Nursery, being treated by Chiyo. The detective Naomasa arrives who All Might knows and asks him about the students' conditions, as well as Shota and Thirteen. Naomasa tells him that the students are unharmed, but Shota and Thirteen are injured, but not in danger of death, relieving All Might worries. All Might tells Naomasa that the students fought bravely and that they will become great heroes, to which the detective agrees.

U.A. Sports Festival Arc
All Might is seen in the meeting room, commenting on Tomura's arrogance and when he started to panic when things went wrong. After taking Tomura's childish personality into consideration as well as his determination, All Might concludes to those in the meeting room that Tomura is a mere character who believes that he is the center of attention, an "adult-child".

After the meeting, All Might finds Izuku and asks him to have lunch with him. In the resting room, All Might asks him how he is handling his Quirk and Izuku replies that he has gained adjustment to the Quirk, saying that he did not break his arm when punching Nomu, which pleases All Might.

He then tells Izuku that his time as the Symbol of Peace is heading to an end, much to Izuku's sadness. All Might says that the U.A. Sports Festival is an event the whole country will be watching and tells Izuku that in the event he wants the whole world to know that he is the new generation's "All Might" and the future Symbol of Peace, shocking Izuku. All Might states that he wants Izuku to demonstrate his full potential to everyone at the Sports Festival.

After Izuku doubts himself, All Might encourages him, stating that the difference between someone who aspires to the top and someone who does not will have a huge influence when he steps up and steps forward in society. All Might says that he understands Izuku's feelings towards his condition and will not force him to do anything, but asks him to remember his feelings during the time he cleaned up the Seaside Park.

At the Sports Festival, after Izuku places first in the Obstacle Race, All Might smiles and claps for him. All Might then ponders about Katsuki, thinking that his ranking in the Obstacle Race, combined with the sheer versatility of his Quirk makes him a popular choice for a teammate. Near the end of the Cavalry Battle, after seeing Katsuki using strategy to get Neito Monoma's last headband, All Might comments to himself that Katsuki, despite no one telling him, is grasping instinctively the difference between those who do not necessarily aim for the top all of the time and those who always do.

After the lunch break begins, All Might in his hero form greets Enji, saying it's been a while and asks him to have tea with him. All Might says that they have not spoken to each other in ten years and that he wanted to give him a shout out, Enji replies that he can take his tea offer to some other place and tells him to go away. As Enji leaves, All Might stops him, saying that his son Shoto was able to show a great performance even without using half of his power. All Might then asks Enji for advice on how to raise the next generation. Enji comments on All Might's attitude, finding it to be annoying and then says that he will make Shoto a hero that surpasses All Might, then angrily walks away.

All Might goes to see Izuku before the beginning of his match. After Izuku says that he can raise his strength only a little with One For All, All Might says that originally, on a scale of one to a hundred, the amount of strength Izuku's body could tolerate it was zero, but now it is a five. When Izuku starts frowning, All Might cheered him up; telling him to do his best and encourages him to smile when he is full of fear and anxiety. All Might then concludes that he is always watching Izuku.

Izuku manages to move on to the next round after defeating Shinsho, but not without problems, since something strange happened with the One For All. All Might goes to the infirmary to see Izuku. After Chiyo scolds All Might for putting pressure onto Izuku, Izuku tells All Might about the mysterious shadows he saw, saying that the shadows helped him break free of Hitoshi Shinso's Brainwashing and asks All Might if what he saw were the people who wove the power of One For All.

All Might replies that he too saw something similar to what Izuku saw in his younger days. All Might theorizes that the people he saw were imprints of those who have used One For All but not the sort who have a will on their own and concludes that Izuku broke Hitoshi's spell, not because of the predecessors of One For All but because his unwilling of willpower caused the vision to appear that broke Hitoshi's brainwash.

Izuku is not completely satisfied with the explanation, but All Might tells Izuku not to dwell on it and tells him to go watch the next match. After Izuku leaves, Recovery Girl says that Izuku also saw him in the vision, to which All Might replies that it is a good thing.

The tournament continues until it is Izuku's turn again. During the match between Izuku and Shoto, All Might watches on, worried about his student's health. After Izuku states to Shoto that becoming Number One without his full strength as well as to disown someone is a joke, All Might remembers Endeavor's words of making his son surpass him. Soon after remembering, All Might theorizes to himself that Shoto won't use his firepower due to the discord between him and his father. He then tries to figure out what Izuku is trying to do. After Shoto activates his firepower, All Might concludes that Izuku is trying to save Shoto from his cruel fate, despite wanting to win. All Might notes that Izuku is going out of his way to help his opponent, causing him to wonder which of them is the joke.

After Izuku is defeated by Shoto, All Might goes to Recovery Girl's Nurse's Office to see Izuku. She scolds All Might for making Izuku push his limits and tells All Might not to try and praise Izuku for going so far. When Izuku apologizes to All Might for not living up to his expectations, All Might's face is filled with regret. After Izuku tells All Might that all he wanted to do was help Shoto and asking for forgiveness, All Might responds by saying that his match was simply an unfortunate outcome but praises Izuku for helping Shoto with his problem, saying that reaching out and helping people with their personal problems is one of the principal qualities of a Hero, happy that Izuku has such a quality.

After Izuku's surgery is finished, Chiyo tells All Might to try and find a different method for Izuku to use his One For All. Izuku leaves Chiyo's room with All Might and they walk down the corridor. Izuku sadly tells All Might that he thinks someone else should be his successor. However, All Might tells Izuku that he used to be Quirkless just like him, which surprises Izuku. Izuku says to All Might that he never knew about that information causing All Might to reply that Izuku never asked him.

All Might tells Izuku that he chose him to be his successor at first due to him being similar to his former self and admits to Izuku that he has surpassed his expectations after seeing Izuku's actions. He then says to Izuku that only he will be able to truly shine with the power of One For All. Having been cheered up by his mentor, Izuku apologizes to All Might. All Might tells him to watch the rest of the U.A. Sports Festival, to which he complies.

All Might, in his Hero form, appears at the closing ceremony of U.A.'s Sports Festival to hand out medals to the winners of the Freshmen Stage: Fumikage Tokoyami, Shoto, and Katsuki. As All Might makes his way into the stadium, Midnight unintentionally talks over him, ruining All Might's entrance. All Might gives Fumikage his medal for placing third, congratulating and acknowledging his strength. He gives Fumikage a pat on the back and a congratulatory hug, telling Fumikage that in order to defeat his problem with unfavorable matchups he should not always rely on his Quirk and that he should increase his own strength to deal with unfavorable matchups better.

All Might gives Shoto his medal for placing second, congratulating him and understands that Shoto had his reasons for suppressing his fire side in the final match. After Shoto tells All Might that he must come to terms with things to solve his problems, All Might gives Shoto a congratulatory hug, saying to Shoto that he will not pry any further and that he knows fully well that Shoto can solve anything with his power.

All Might then goes to give Katsuki his medal for first place, finding the restraints to be a little too much. All Might takes Katsuki's face mask off, causing Katsuki to angrily yell that he does not deserve to be Number One. However, All Might tells Katsuki that society will acknowledge him as Number One even if he does not. All Might gives Katsuki his medal.

Afterwards, All Might gives a speech to everyone, saying that everyone who participated in the Sports had a chance to stand on the podium. He goes on to say that the future generation of heroes looks bright. All Might yells out "Great Work", much to the confusion of the crowd who thought he would yell "Plus Ultra", causing him to reply that he thought "Great Work" would be far more appreciative.

Vs. Hero Killer Arc
All Might is in U.A.'s Faculty room. Ken Ishiyama informs All Might that a new nomination has just arrived for the freshmen, telling All Might that the nomination is for Izuku. Excited, All Might goes to check who nominated Izuku. As he checks, All Might becomes flabbergasted at the person who nominated Izuku.

After school that day, All Might appears in front of Izuku as he is about to leave class. All Might and Izuku walk along the corridor. All Might says that Izuku received a nomination, much to Izuku's surprise. All Might tells Izuku that the person who nominated him was Gran Torino. All Might explains that Gran Torino was a Pro Hero who taught at U.A. for one year and that Gran Torino was his homeroom teacher. All Might says that Gran Torino was a close friend of his predecessor, but now he is in retirement. All Might says that Gran Torino knows about the One For All Quirk which is the reason why he must have nominated Izuku.

Shaking nervously, All Might wonders if Gran Torino was compelled to nominate Izuku due to him thinking that his guidance towards Izuku was lacking, becoming terrified by the fact that he is taking up his Hero Name again. While trying to stop his legs from shaking, All Might tells Izuku that while it is his duty to train him, he should select Gran Torino as his work place of choice and see what he can learn from him. Before leaving, All Might informs Izuku that his hero costume has been repaired.

Naomasa meets with All Might at U.A. He tells All Might that the Police Force has tried everything to get information out Nomu; however, everything they tried did not work. Naomasa says that they instead looked into Nomu's background through DNA analysis and have discovered that Nomu was once a human with a criminal record. Naomasa explains that the DNA analysis also revealed that Nomu has the DNA of at least four different humans mixed with his own. Naomasa concludes that Nomu is an artificial human-made to measure up to multiple Quirks and that having all the DNA in his body as well as his body modified caused Nomu's brain activity to stop.

Naomasa tells All Might the real issue is that Nomu's DNA is of primary concern because it contains multiple Quirks. Naomasa says that Nomu could not have acquired multiple Quirks in any way (unless Nomu acquired the Quirks through advanced genetic familial permeation). Naomasa comes to the conclusion that someone with a Quirk that can grant Quirks is behind Nomu's acquisition of multiple Quirks. All Might becomes concerned as he fears that All For One has returned.

After Stain's defeat is published, Gran Torino speaks to All Might using a telephone. Gran Torino expresses his annoyance that his pay has been cut in half and his right to teach is revoked for half a year but says that considering the circumstances he does not mind. Gran Torino tells All Might that Izuku has improved drastically in using One For All, saying that Izuku movements are similar to his own; All Might apologizes profusely and thanks Gran Torino for his help, admitting that his teaching towards Izuku has been inadequate. Gran Torino says that he only became qualified as a teacher so that he could keep his promise to Nana Shimura, All Might's predecessor.

All Might thanks Gran Torino for everything as he wouldn't be the man he is today without him; Gran Torino brings up that All Might never visits him, to which All Might nervously says that his teacher's life was busy before his master tells him he is calling him about the encounter with the Hero Killer; he admits that Stain's strong ideology is similar to All Might's. Gran Torino says that if Stain's backstory is revealed to the public through the use of media, villainy will rise and the League of Villains will take credit as a group following Stain's ideology due to the connection between them, which will cause delinquents to join the League of Villains.

Gran Torino states that he believes that an old enemy will use Stain's backstory to remove obstacles in his path. Gran Torino hypothesizes that the old enemy, the villain who killed All Might's predecessor and gave All Might his scars, All For One has returned. All Might is in disbelief that All For One had survived, not wanting to believe it given the serious injuries All Might inflicted on him. Gran Torino advises All Might to reveal to Izuku everything about himself and One For All when the opportunity arises.

The workplace training comes to an end and Class 1-A returns to U.A. Class 1-A next class is Foundational Hero Studies with All Might. All Might says that their lesson will be a Rescue Training Race through Playing Ground Gamma (a construction site with many densely packed lanes which makes it look like a labyrinth). The class must race through the construction site and to the area in the middle to meet up with All Might. Class 1-A will split into four groups of five for the training lesson.

Izuku, along with Mashirao Ojiro, Tenya Ida, Mina Ashido, and Hanta Sero are the first group that will partake in the rescue training race. All Might watches the race and is surprised and amazed at Izuku's new control of his Quirk and his movements. After the race ends, All Might commends the group on improving their Quirks more broadly since entering U.A. He asks them to prepare for the end-of-term test. All Might then approaches Izuku, telling him that he is impressed with his improvement and gives him a thumbs up. All Might tells Izuku that after the lesson is finished, he should come to his place because he wants to talk to Izuku about the story of him and One For All.

All Might meets with Izuku in the Break Room. All Might tells Izuku to lock the door and then apologizes to Izuku for not being at his side during the Hosu incident, to which Izuku replies that he does not have to apologize. All Might says that Izuku's blood was ingested by the Hero Killer, reminding Izuku about One For All transfer and inheritance method, causing Izuku to panic (thinking that One For All is in Stain's possession). However, All Might tells Izuku that he still has One For All because One For All will not be transferred to a new recipient unless the user wishes it, thus One For All cannot be forcibly stolen, although it can be forcibly passed on. All Might tells Izuku that One For All is a special Quirk and begins telling Izuku One For All's origin. All Might says that One For All is derived from a Quirk that has existed since the beginning.

All Might says that long ago during the Quirk phenomenon, society had not adapted to the idea of having Quirks which caused an age of upheaval to arise; a man possessing a Quirk called All For One (a Quirk that can steal Quirks and grant them) stole many Quirks and used his new overwhelming power and influence to gather and unify people under his command. The man used the people he gathered as pawns for his plans which allowed to take over Japan and made himself its evil ruler. Izuku says that he has heard rumors but this story is not in any textbook causing All Might to reply that underground dealings are never recorded in the textbooks.

Izuku asks how this man is related to One For All. All Might says that All For One can grant Quirks, but those who were not able to handle the strain became brain-dead like Nomu. All Might explains that there were cases for those who did survive the procedure where their Quirks mutated. All Might tells Izuku another story; the man (who would eventually become Japan's evil ruler) had a younger brother; the man used All For One and forcibly gave his younger brother a Quirk that stockpiles power. However, the younger brother already had a Quirk, a Quirk that can transfer itself to others. The younger brother's Quirks (one that stockpiles power and the other that can transfer itself) merged and became One For All.

All Might notes the irony that justice was born in the bowels of evil. Izuku says that it is impossible for the man who ruled Japan in the distant past to be alive. All Might theorizes that the man stole a Quirk that stopped his aging or a Quirk that granted him immortality. All Might explains that the younger brother, whose Quirks became One For All, fought against his older evil brother but could not defeat him.

The younger brother decided to pass on One For All to the next generation so that one day it will accumulate enough power to defeat the older brother's All For One; All Might says that he was finally the successor that defeated the older brother, or so he thought. All Might tells Izuku that the man possessing All For One has returned and is leading the League of Villains. All Might finishes his story by saying that One For All is a power that is meant to stop All For One and that Izuku will also have to confront the man.

All Might apologizes for giving Izuku so much information. Izuku says that whatever task All Might gives him he will accomplish no matter what as long as All Might is by his side. All Might is not able to bring himself to tell Izuku that he will not be able to remain by his side when the time comes and thanks him instead.

Final Exams Arc
U.A.'s First Term Final Exam are mandatory exams taken by U.A.'s Hero Department students at the end of the first semester. It consists of two exams, written one and a practical test in which the students must face the teachers in mock battles. Izuku and Katsuki are paired together and must fight All Might in their end of term test exercise. All Might tells the wonder duo to cooperate together and come at him to win.

All Might, Izuku, and Katsuki get onto a bus and drive to an uninhabited city where the test exercise will take place. All Might, Izuku, and Katsuki arrive in the city. All Might explains the test exercise: Izuku and Katsuki have two options of winning and passing the test exercise; they must either handcuff All Might or one of them must escape from the battlefield. Izuku and Katsuki have to accomplish either fighting to handcuff their opponent or one of them must escape the battlefield in 30 minutes. Izuku notes that this will test their flight or fight decision skills. All Might puts on super-compact weighted bracelets to give himself a handicap. The test exercise begins. After a while passes, Izuku and Katsuki begin arguing. Suddenly, All Might throws a punch which devastates the area Izuku and Katsuki are in; All Might says that he will have to get involved.

Izuku is shocked at the level of All Might's (even though he knows that All Might is handicapped and severely weakened to begin with). All Might declares to the duo that he is a villain and collateral damage means nothing to him. All Might charges at the duo. Feeling All Might's pressure, Izuku tells Katsuki that they have no chance of winning and should run away. However, Katsuki refuses to run away.

Katsuki uses Stun Grenade against All Might which distracts him. Katsuki charges at All Might, but the Symbol of Peace grabs Katsuki's face, stopping his advance. Katsuki launches a flurry of Explosions against All Might. However, Katsuki's Explosions do not even scratch All Might. All Might slams Katsuki down onto the ground. All Might turns his attention to Izuku who planned on running away. All Might questions Izuku on his decision to escape. Izuku recalls the Hero Killer and activates One For All: Full Cowl, wondering why he suddenly recalled the Hero Killer. Izuku jumps into the air, but Katsuki has also jumped into the air; the duo collides into each other as a result.

All Might appears in the air with a guardrail in his hands; All Might slams the guardrail on Izuku which pins him down to the ground. Then, All Might punched Katsuki in the stomach, greatly injuring him and sending him flying backward. All Might approaches Katsuki and says that he understands his jealousy of Izuku's sudden growth; All Might tells Katsuki that what he is currently doing is a waste and must grow his willingness to borrow other peoples' strength.

The weakened Katsuki struggles to get up and tells All Might that if he must rely on other peoples' strength, then he would rather lose. Disappointed with Katsuki's decision, All Might prepares to finish off Katsuki; Katsuki tries to move but to no avail. Suddenly, Izuku activates One For All Full Cowl and breaks free of the guard rail; Izuku charges and punches Katsuki out of harm's way.

All Might chases after Izuku and Katsuki. Suddenly, Katsuki appears from behind and attacks All Might with an Explosion which distracts All Might. However, one of Katsuki's Grenadier Bracers is missing. Suddenly, Izuku appears behind All Might with Katsuki's missing Grenade Bracers equipped on him. Katsuki yells at Izuku to commence his attack; Izuku aims the Grenade Bracer at All Might and releases the grenade pin.

Izuku releases the grenade pin and blasts an immense Explosion at All Might at point blank range. After the Explosion is finished, Izuku and Katsuki dash towards the exit. All Might easily takes the Explosion, only coughing up a little blood. All Might is impressed with the duo's strategy; All Might notes that while their relationship will not improve immediately, Izuku and Katsuki's cooperation with each other in this practical test will be a great leap forward for them in the future. All Might decides to chase after the escaping Izuku and Katsuki, declaring that he will give it his all.

All Might catches up to Izuku and Katsuki and defeats them; All Might pins Katsuki down on the ground with his foot and dangles Izuku in the air with his arm. All Might praises Izuku and Katsuki for working together to try and defeat him but reminds them that working together is merely a per-requisite of the practical test.

Recovery Girl announces that Shoto and Momo are the first team to pass the exam. All Might is surprised to learn that his colleague, Shota, has been defeated. All Might smashes Katsuki into the ground with his foot. Katsuki finally understands that All Might is far too overpowered for him to stop and realizes that All Might is truly the strongest Hero and the world's most sky scrapping wall. Izuku tries activating One For All Full Cowl, but All Might stops him and throws him onto the ground. All Might decides to finish off Izuku and Katsuki.

Suddenly, Katsuki gets up and launches a big explosion against All Might, which distracts the Symbol of Peace. While All Might is distracted by the light, Katsuki grabs Izuku and throws Izuku towards the escape gate with an Explosion. To prevent Izuku from escaping, All Might uses New Hampshire Smash and blasts himself into Izuku which crushes Izuku due to All Might's great weight and sends him tumbling down.

Katsuki chases after All Might; Katsuki tells All Might that the Grenadier Bracers were to help him use his maximum Explosions without risk and admits that he was a fool for thinking that he could win without taking risks. Katsuki uses a huge explosion against All Might (similar to the explosion in the U.A. Sports Festival) and tells Izuku to escape; Izuku struggles to get up. Katsuki decides to sacrifice himself to hold off All Might so that Izuku has time to escape; Katsuki uses another huge Explosion against All Might. However, although the great Explosions have distracted All Might, the Symbol of Peace is still unscathed.

Izuku gets up and prepares to activate One For All Full Cowl so that he can leap towards the escape gate. Not allowing Izuku to make an escape, All Might prepares to attack Izuku but Katsuki intercepts All Might's attempt. Izuku successfully activates One For All Full Cowl and begins his escape while All Might smashes Katsuki into the ground. Izuku sees that Katsuki is in trouble. Despite being greatly injured, Katsuki yells at Izuku to escape and bites All Might's hand. All Might ignores Katsuki's desperate attempt and tells Izuku that he won't allow him to escape.

Surprisingly, Izuku does not rush towards the escape gate; instead, Izuku rushes back to help Katsuki. While rushing to help, Izuku remembers All Might's words; that when times are scary and uncertain, you face it all with a smile. Izuku smiles and punches All Might in the face. While All Might is suffering from slight recoil, Izuku grabs Katsuki who has fallen unconscious. Izuku rushes towards the escape gate with Katsuki in tow. All Might shrugs off Izuku's punch and watches him escape. All Might understands by now that Izuku is the type of person to save somebody; All Might notes that whenever Izuku tries to save somebody, there's never a wall in his way.

After Izuku and Katsuki pass the practical exam, All Might carries them to Recovery Girl's tent to be healed. Recovery Girls scolds All Might for not restraining himself during his battle with Izuku and Katsuki. Recovery Girl asks All Might to take Izuku and Katsuki back to U.A. to recover. After Izuku requests to stay, All Might leaves carrying an unconscious Katsuki in his arms, he notes that Izuku will be extraordinarily strong one day. All Might walks out of the tent and prepares to carry Katsuki back to U.A. All Might notes that Katsuki himself is also incredible and that whenever there is a wall in front of Katsuki, he laughs at it.

My Hero Academia: Two Heroes
Before the special training exercise Toshinori reserved an email, but didn't get the chance to read it. After the training exercise was over Toshinori went to the computer and remember that he got an email. After looking at it on who it was from Toshinori realized that it was from Melissa. She invited him to I-Island for the preview of I-Expo. Toshinori laid back into his chair, and had a flashback when the time he told David that he want to become the symbol of peace, to shine a light in the world. When Izuku was on the way home, Toshinori in his muscle form gave him a surprise visit. Toshinori quickly turned back into his skinny form. Izuku asked what was he doing there, Toshinori asked Izuku if he has heard of I-Island. This has caused Izuku to start his muttering habit going way too many details, Toshinori asked Izuku if he wanted to go there with him. Toshinori said that as his successors he needs to learn a lot new tricks than traits their. Izuku agreed to go, Toshnori told him to quickly go up to his room a pack a bag. Toshinori told Izuku that they will be going soon.

On the plane ride to I-Island, Toshinori fell asleep and had a dream about his time at America. Toshinori remembered when he and David had stopped the L.A. Villains before their class lecture took place. He wakes up to Izuku calling his name repeatedly, as they are almost at I-Island. The plane lands, and All Might transforms into his muscular form, and double checks everything including if Izuku got permission to bring his hero costume along.

On I-Island, All Might is met with a swarm of adoring fans, much to his and Izuku's dismay. The interactions takes longer than expected, making All Might late to meet his old friend, David. Suddenly, Melissa Shield bounces over to the two on her advanced pogo stick and greets "Uncle Might." They are thrilled to see each other again, and All Might introduces Melissa to Izuku, and the two quickly get acquainted. All Might interrupts them when Melissa gets close to Izuku and notices his scars, reminding her of their agenda.

All Might surprises David in his laboratory, who is very happy to see his old friend. He introduces David to Izuku, but the latter already knows all about the professor. David notices steam coming out of All Might's body, so he asks Melissa to show Izuku around the expo and give them some time alone. After they leave, All Might reverts to his weak form, and David is surprised at the injuries despite being informed via email.

David examines Toshinori on a medical bed and is horrified to see that his Quirk levels have dropped drastically. He asks Toshinori about it, but the latter gives a vague response, as David does not know about One For All. David worries that without All Might, Japan's low crime rate will rise once again, but All Might reassures him, saying that the symbol of peace is still alive. All Might shifts into his muscular form and leaves the lab, promising to meet David at the reception party.

At the party, All Might gives a speech, but is abruptly interrupted when the I-Island Security System sets off an alarm across the whole island, locking the building from the outside. The villain Wolfram and his crew barge into the party with guns, threatening to use the security bots to hold everyone on the island hostage. All Might and the Pro Heroes at the party are restrained by powerful bond shots from the ground. David convinces All Might to comply with the villains and swears to find a way to save everyone.

Wolfram takes David and his assistant, Samuel Abraham, while All Might can't do anything as he watches. All Might then notices Izuku flashing light at him from the third floor, and All Might discreetly explains the situation. Izuku relays a message saying that Class 1-A and Melissa will disable the security system to save everyone. While All Might mostly disapproves, he puts his faith in his pupil and remains constricted on stage.

All Might had trouble maintaining his muscular form, but found an opening when Melissa disabled the security system, freeing him of his restraints. Melissa calls All Might and updates him on the stakes, and he promises to rescue Izuku and David. As Wolfram was about to escape with David Shield, All Might leaps high above their helicopter and rescues his friend. David tries to apologize, but Wolfra attacks them both with a metal pillar and traps David in a metal casing. Wolfram, using David's Quirk Amplification Device, proves to be powerful, and nearly crushes All Might, but he is saved by Katsuki and Shoto, who are accompanied by the rest of Class 1-A. Motivated by their heroic spirits, All Might goes beyond his limits and breaks through Wolfram's iron defenses.

However, Wolfram uses his surprise Muscle Augmentation Quirk and metal wires to trap All Might. All Might is shocked, and deduces that Wolfram got his power from All For One. All Might's smile begins to fade when he realizes that his nemesis attempted to twist his best friend to darkness, but Izuku rescues him with a powerful kick. All Might scolds Izuku for his reckless use of One For All, but his smile returns and thanks his successor. The two race into the final battle and rush past a barrage of metal assault and defeat Wolfram with a Double Detroit Smash. All Might goes to check up on David, who admits that he was afraid that the Symbol of Peace would fade away. David realizes that he was clinging onto the past, and knows that Izuku and Melissa can ensure a bright future. All Might says that Izuku isn't ready yet, but adds on that he has the potential to be the greatest hero.

Forest Training Camp Arc
After The Hero Incident involving Izuku and Tomura Shigaraki occurs, Toshinori goes to the Police Station. Outside the Police Station, Toshinori greets Izuku and Naomasa; Toshinori apologizes to Izuku for not being there. Thinking about his conversation with Tomura, Izuku asks Toshinori if there were times when he failed to save someone. Toshinori tells Izuku that there were many times he could not save someone; Toshinori modestly admits that he is only human and cannot save everyone. Toshinori notes that his title, the Symbol of Peace, serves to inspire people and Heroes to play their roles so that more people can be saved. Inko Midoriya arrives to pick Izuku up; Izuku comforts his crying mother, telling her that everything is fine.

After Izuku and his mother leave, Naomasa theorizes that Tomura will probably target other students and decides that Hero schools must exercise more caution and become more proactive in implementing countermeasures against villains. Naomasa advises Toshinori that leaving U.A. is also an option, but, Tdecides against it. Naomasa concludes their conversation by saying that they will capture All For One this time, to which Toshinori agrees.

When summer break begins, students go to a training camp to improve their Quirks, but on the third day of training, the League of Villains attacks the place and kidnaps Katsuki, leaving several students and professors hospitalized. One day later after the League of Villains' Vanguard Action Squad capture Katsuki, Toshinori is in a meeting with the U.A. faculty. In the meeting, Toshinori is ashamed of himself for lounging around while his students were out fighting for their lives. Toshinori leaves the meeting when he gets a phone call from Naomasa, who informs him that they have located the League of Villains' hideout and requests his help in the rescue operation.

Before carrying out the operation, All Might and Naomasa visit Momo at the Hospital. She explains that Yosetsu Awase had planted a transmitter she had created onto the Nomu, and handed a device to All Might that will allow him to locate the transmitter. All Might applauds Momo's growth and found her to be worthy of being a hero, asking her to leave the rescue of Katsuki to him.

Hideout Raid Arc
The next day at night, Toshinori along with the police and a large number of Pro Heroes await for their infiltration of the League of Villains' hideout. While waiting, Toshinori and Gran Torino converse to each other that All For One is making his move. The infiltration begins with the Police Force and the Pro Heroes standing outside the League of Villains' hideout; Toshinori prepares to attack.

Toshinori breaks into the hideout with Kamui Woods swinging in and restraining the League of Villains with his Lacquered Chain Prison while Gran Torino stops Dabi from using his Quirk with his kick. Toshinori checks Katsuki and compliments him for not being afraid, much to Katsuki's chagrin. After Kurogiri's attempt to bring the Nomus fail, Toshinori criticizes Tomura for underestimating them and declares that it is game over for him and his League of Villains.

However, Tomura refutes Toshinori's claim and orders Kurogiri to create portals so that they can escape, but Edgeshot knocks Kurogiri unconscious. Gran Torino asks Tomura the location of his boss, All For One. Tomura does not answer and instead screams out his hatred for Toshinori. Suddenly, a mysterious black liquid appears out of thin air with Nomus appearing out of the phenomenon which surprises the League of Villains and the Pro Heroes; Edgeshot notices that the black liquid is not Kurogiri's doing since he is unconscious. More Nomus begin appearing from the masses of the mysterious black liquid. Toshinori grabs Katsuki. However, Katsuki begins dissolving into the black liquid and disappears, much to Toshinori's fury.

Tomura, Kurogiri, and the Vanguard Action Squad are entrapped in the mysterious black liquid. Toshinori and Gran Torino attempt to stop them but the mysterious black liquid teleports Tomura, Kurogiri, and the Vanguard Action Squad away from the hideout. Kamui Woods mulls over his failure in restraining the League of Villains while Edgeshot tells him not to worry since they could not do anything either. Four Nomus attack Toshinori, and he defeats them with Oklahoma Smash. Outside the hideout, Naomasa along with Enji and the Police Force continue battling the dozens of Nomu's and have the upper hand. Toshinori appears and decides to leave the rest to Enji.

Toshinori manages to find All For One and attacks him, but All For One blocks the attack. Toshinori declares that he will take everything back while All For One wonders if the Symbol of Peace will attempt to kill him again.

All Might and All For One clash, which creates a shockwave that sends Katsuki, Tomura and the Vanguard Action Squad backwards. Both All For One and All Might criticize each other for becoming weaker. All Might declares that he will save Katsuki and won't repeat the same mistake as he did five years ago and this time he will definitely put All For One behind bars along with the League of Villains. All Might charges at All For One. However, All For One sends a huge blast wave at All Might, causing the Symbol of Peace to be sent flying away at great force. All For One's blast wave attack not only hits All Might but destroys several buildings in the process.

Despite being sent several miles away, All Might quickly recuperates and returns to the battlefield by jumping to it, refusing to allow All For One to escape and charges at him. All Might and All For One clash once again. Meanwhile, Katsuki is fending off some of the Vanguard Action Squad; All Might attempts to help Katsuki only for All For One to intervene and stop him. Suddenly, Izuku, Eijiro, and Tenya appear above in the air; All For One sees the trio and attempts to attack them, but All Might intervenes by punching All For One.

All Might is surprised with Izuku and the other students' presence. Gran Torino appears at the battlefield, knocking out Spinner, Magne, Mr. Compress and is annoyed that Izuku has taken on All Might's characteristics, while All Might himself is still surprised that Izuku and some of his fellow students came to rescue Katsuki. However, All Might is pleased with their intervention as he can now fight All For One without holding back.

After Izuku and his friends flee with Katsuki and Tomura along with the Vanguard Action Squad are teleported away, All Might charges at All For One, but All For One uses his Warp Quirk to teleport Gran Torino in front of him, using the elderly Hero as a human shield which causes Gran Torino to take All Might's attack instead. All For One expresses his hatred for All Might as he is the one who brought down his comrades in the past and while he descended into darkness, All Might rose to the top as the Symbol of Peace. All For One prepares to fire his blast wave move, intending of blowing away Gran Torino and All Might at the same time. However, All Might pulls Gran Torino away and uses Detroit Smash to cancel out All For One's blast wave move.

All For One sees that his destruction of the city has brought chaos and decides to put the innocent civilians in danger so that All Might won't be able to fight at full strength. Furious with All For One's sadism, All Might grabs his arm while throwing Gran Torino away for safety. All Might admonishes All For One for all the despicable crimes he has committed and for his misanthropy.

All Might punches All For One in the face, shattering his mask; however, All Might's punch wasn't strong enough to finish off All For One. As Gran Torino calls out to him, All Might turns back into his true form. All For One says that All Might would not be the first to criticize him as he has heard those same lines before, from the previous One For All successor: Nana Shimura.

All Might whose face has partially reverted to its true form is angry at All For One for mentioning his predecessor's name, Nana Shimura. All For One notes that Nana Shimura was all bark and no bite, only going on about her ideals and was not even strong; All For One mocks Nana for her uselessness and mentions that she died an embarrassing, shameful death. Furious, All Might prepares to attack All For One. However, All For One uses his blast wave technique against All Might, causing the Symbol of Peace to be blasted into the air. Gran Torino catches All Might and lands him to safety on the ground. Gran Torino advises All Might to not listen to All For One's provocations and that due to All For One's different Quirk usage and strategies; he should only attack when All For One lets his guard down.

Up in the sky, news helicopters are broadcasting the battle. All For One decides to sever the trust in Heroes once and for all. All For One once again expresses his hatred for All Might due to taking something away from him and wants him to die in the most gruesome way possible.

All For One fires another blast wave attack at All Might. All Might, seeing that an innocent civilian is trapped under rubble behind him, blocks All For One's blast wave attack which saves the civilian from being harmed. However, All Might who blocked the blast wave attack has caused him to expend his power and he reverts to his true form. All For One relishes in the fact that All Might's true form has been exposed for all to see.

Everyone around the country sees All Might's true form and begins panicking. All For One mocks All Might for the pitiful state he is in. However, All Might doesn't care about his rotting body nor his exposure to the world; Toshinori declares that his spirit burns strongly which is what truly matters. Wanting to break his spirit, All For One reveals that Tomura Shigaraki is Nana Shimura's grandson, which demoralizes All Might.

All Might refuses to believe, but All For One tells the Symbol of Peace that it is the truth. All For One wonders why All Might isn't smiling and sarcastically remarks about All Might's smile, which is something Nana would always do. All Might's spirit is greatly demoralized by All For One's sarcasm while All For One continues relishing in All Might's pitiful state. However before he could fall in complete despair, the innocent civilian under the rubble encourages All Might to win and help her.

Around the country, the people who are watching refuse to believe that All Might will lose even though he isn't at his best and do not care about his true form since he has attained victory one way or another. Many citizens who are watching rally behind All Might and encourage him to win. In response to this, Izuku and Katsuki also encourage All Might shouting at him to win. Invigorated by the civilian pleas, All Might regains hope as he activates One For All throughout the right side of his body, transforming it back into its Hero form. All Might smiles and states that Heroes have many things to protect which is why they don't lose.

All Might activates One For All throughout the right side of his body. Endeavor, Edgeshot, and Kamui Woods arrive; Endeavor and Edgeshot fight All For One with the former flabbergasted with All Might's appearance. Kamui Woods rescues Best Jeanist, Mt. Lady, and Gang Orca while Tora rescues the trapped civilian; Tora encourages All Might to win since he is everyone's Number One Hero.

Growing tired with the sentimental talk, All For One blasts Endeavor and Edgeshot back. All For One activates a numerable amount of his Ultimate Combination, causing it to become an enlarged mutated arm filled with numerous deadly screws and hardened minerals.

All For One charges at All Might with his heavily empowered and mutated arm. While heading towards All Might, All For One knows from battling him that All Might no longer has One For All and tells All Might that the person who was given One For All by him is Izuku. All For One taunts All Might by saying that he has also failed as a teacher towards Izuku due to his apprentice's recklessness. Both All For One and All Might clash by punching each other with their enhanced fists, which creates a huge shockwave that devastates a great portion of the city.

As they struggle, All For One uses his impact Recoil Quirk to revert all the damage to All Might. However, All Might transfers One For All to his other arm, sacrificing his right arm but rendering Impact Recoil ineffective. All Might says that he must indeed criticize Izuku for his actions. All For One is shocked that All Might would go to such lengths to protect his leftovers of One For All and admits that he miscalculated. All Might refuses to die until he has finished bringing up Izuku, he then counters by throwing his empowered left arm and punch at All For One who has left his guard open.

All Might punched All For One, successfully hitting him. However, the punch All Might delivered was meant to lower All For One's guard which worked. All Might transfers One For All to his right arm and prepares for his final attack he will ever use. All Might uses United States of Smash on All For One, which creates a great shockwave. After the dust clears, All For One is in a crater, badly beaten and unconscious.

All Might raises his arm to signify his victory; the reporter from the news helicopter announces All Might's victory. All Might transforms into his Hero form while raising his arm, signifying that he is the Symbol of Peace which causes the citizens watching to start celebrating; Edgeshot wants All Might to preserve his strength, but Gran Torino stops him as he wants All Might to enact his dream of being the Symbol of Peace for one last time.

With the battle over, Pro Heroes begin carrying out rescue operations to save people who are trapped under rubble as a result of All Might and All For One's battle. Meanwhile, Endeavor and All Might watch All For One being placed in the iron maiden. Now that All For One is properly imprisoned, All Might points to the camera and delivers a message "you're next". The citizens watching take All Might's message as a warning to all villains out there, causing the citizens to praise All Might and start celebrating again. However, Izuku knows what All Might's message truly meant; that his time as Symbol of Peace has come to an end and he (Izuku) is the next successor. Izuku now realizes that All Might's time has truly come to an end and starts crying.

At a hospital, All Might who is bandaged and recovering states that he can no longer use One For All and that although he can no longer be the Symbol of Peace, he still has things to do. Naomasa is in disbelief that Tomura Shigaraki is Nana Shimura's grandson. On that topic, Gran Torino comments that Nana Shimura and her husband had a child. However, after her husband died due to heroics, Nana sent her son to a foster family so that he can stay away from the world of heroics. Nana then informed Gran Torino and Toshinori to not get involved with her son.

All Might wishes to find Tomura, however, Gran Torino tells All Might that he is in no position to help Tomura since he has would not be able to see Tomura as a villain. Gran Torino and Naomasa decide that they will handle the search for Tomura. Gran Torino suggests to All Might that he must remain at U.A. and carry out what he must still do; helping his successor, Izuku Midoriya.

All Might meets Izuku at the Takoba Municipal Beach Park. All Might greets Izuku with a Texas Smash to the face as a part of his scolding. All Might reveals to Izuku that he can no longer use One For All and demonstrates this by entering his Hero form, only to exit it in a split second afterwards. All Might informs Izuku that he is retiring as a Hero since he is in a state where he cannot fight anymore.

All Might scolds Izuku for never doing what he is told and for his recklessness in rescuing Katsuki. However, All Might is glad that his recklessness did not get him injured this time and is proud of Izuku for that. All Might hugs Izuku and apologizes for not being a proper mentor towards him, but from now on he will focus solely on Izuku's development and training. Izuku begins to cry, to which All Might scolds him for again while some tears of his own begin to form.

All Might returns to U.A. where Nezu thanks him for saving the day. Mr. Principal announces a plan he would like to implement; transitioning U.A. to a boarding school as a means to mitigate the safety issues and asks for Shota's cooperation.

Shota and All Might visit the homes of Class 1-A. He and All Might visit Kyoka Jiro's home, where Kyoka's father, Kyotoku Jiro, is not too happy with U.A's safety measures and has doubts in U.A's ability to protect her if she were to relocate to U.A's dormitories; Shota acknowledges that U.A. has been negligent in its duty to safeguard its students and vows to correct this safety issue as well as promising to make Kyoka into a fine Hero. Kyoka tells Shota to relax as her father has already agreed to allow her to relocate to U.A's dormitories.

Shota and All Might visit Katsuki's home, where Katsuki's mother, Mitsuki Bakugo, is more than happy to allow her son to relocate to U.A's dormitories. Mitsuki is confident in U.A. because Shota sees her son for who he is instead of what he can do. Mitsuki also reasons that her son, even though she was worried, returned home safe and sound from his captors thanks to the Pro Heroes which is why she is confident in U.A's ability to safeguard and raise her son.

As Shota and All Might leave the Bakugo household, Katsuki appears and asks All Might what Izuku is to him. Unable to tell Katsuki the truth, All Might informs him that Izuku is a student to him who has great potential just like Katsuki. Satisfied to a degree with All Might's answer, Katsuki thanks All Might for everything and goes back inside his house. Shota decides to visit the other Class 1-A families by himself while All Might goes to visit Izuku.

All Might decides to visit Izuku's apartment by himself while Shota visits the rest of Class 1-A. All Might enters the Midoriya Apartment, being uncomfortable with the home possessing fan memorabilia of him. Izuku and Inko are flabbergasted that the Number One Hero has entered their abode. After the three sit down at the table, All Might asks Izuku's mother for her permission to send Izuku to the U.A. dorms. However, Inko is against it. Inko explains that she is worried about her son since his Quirk damages him rather than helps him and is deeply concerned about her son's future as a Pro Hero after witnessing All Might's brutal battle, unable to bear the fact that Izuku will also have to face such bloody battles with no hope possibility of full recovery. Inko states that she has no confidence in U.A. and is unable to entrust her son to them.

Izuku tries to convince his mother that his injuries are a result of his inability to control his Quirk, but Inko replies that regardless it is still the responsibility of U.A. to take care of their students which they have not done. Inko understands that she is being a strict parent but the safety of her child is her number one priority and she is fine with Izuku continuing to become a Hero since it is his dream as long as he is in a safe environment, which is why she wants to send Izuku to another school. Although he understands his mother, Izuku wants to continue his dream at U.A. since that is where All Might became a hero.

Izuku runs out of the room while All Might understands Izuku's frustration; that it must be painful to not being able to study at the same place his idol went to. Izuku returns to the room with a letter in his hand; the letter is a thank you from Kota. Izuku tells his mother that at the training camp, he saved a boy named Kota Izumi, who hated Quirk and heroes because a villain killed his parents. Izuku understands that he has a long way to go but for a little while, Kota and his thank you letter made him a hero. Izuku declares that even if he cannot study at U.A., he will still keep dreaming to become a hero.

All Might is shocked that Izuku is willing to continue his dream even though it is not as the same place as his idol; All Might is impressed with Izuku's growth and is glad that he is going on his own path instead of following him, his idol. All Might transforms into his Hero form and kneels before Izuku and Inko, bowing his head, much to their shock.

All Might apologizes to Inko for his negligence as Izuku's teacher and understands that she is worried about the bloody path of a Hero; All Might asks Inko to allow him to walk together with Izuku down his path so that he doesn't have a bloody future. The former Symbol of Peace also understands Inko's concerns about the current U.A. and tells her that they are reforming their ways. All Might promises that he will nurture and protect Izuku even at the cost of his own life.

Inko is shocked at All Might's resolve, causing her to fall to her knees. Inko states that all she wants is Izuku to be happy and tells All Might that he should never trade his life away for someone else's sake. Inko tells All Might to continue living and that as long as he can protect and nurture Izuku, she will reconsider her decision to not send Izuku to live at U.A. All Might pledges to protect and nurture Izuku while Izuku tells his mother that he will not worry her.

Outside, All Might compliments Izuku's mother, telling Izuku that she reminds him of his master. All Might leaves and tells Izuku that he will see him at U.A.

Provisional Hero License Exam Arc
The Students train under the supervision of Shota, Ken, Nemuri, and Ectoplasm in Gym Gamma. The goal is to develop their Quirks and Super Moves before the Provisional Hero License Exam. All Might appears at the entrance to the gym because he wants to help. Shota tells him he should focus on recovering but All Might replies that it is his job as a teacher to oversee the training of his students. When Katsuki defeated an Ectoplasm clone, Shota and All Might comment on Katsuki's prowess and that he will only keep growing stronger from here on out.

The other students of Class 1-A continue their training and thinking about their special moves while Izuku is still puzzled on what to do next. All Might approaches him and gives Izuku advice: he is still trying too hard to imitate him, which confuses Izuku. Before he can question further, All Might moves on to give advice to Eijiro. All Might is teaching Izuku to think independently. Shota wonders why his sudden interest in helping students, when he spots a book sticking out of his back pocket. It is titled "Even Dummies can be Teachers! Easy Education Theory". Shota is stunned.

Four days later at Gym Gamma in the midst of training, All Might shows up and Shota Aizawa tells him that Class 1-A are progressing nicely. However, the rock Katsuki used to test his AP Shot cracks and begins falling towards All Might. Katsuki and Shota warn All Might, but Izuku jumps out and destroys the falling wall with a single kick, showing his new fighting style, which he names "One For All: Full Cowl - Shoot Style". All Might smiles at Izuku in approval.

All Might comments that Izuku's new fighting style it's a big step in the right direction, and will help him in the Provisional Hero License Exam. Shota warns All Might to stay a safe distance away from the training session to avoid being injured. All Might apologizes to Katsuki, who storms off shortly after telling All Might to be more careful. The former Symbol of Peace is staggered about the fact that throughout his life, he has been protecting others. Now, All Might realizes that he needs others to protect him and is perturbed with the role change.

Several days later, while the students of the U.A. participate in the Provisional Hero License Exam, All Might goes to Tartarus, a special prison for criminals for whom the death penalty is not enough. All Might is there to sits down to speak with All For One. All For One tries taunting him, asking where Gran Torino is and why he has come dressed in his hero costume. All Might ignores him, asking where Tomura is. All For One states he doesn't know and has allowed his successor to carry on his will.

All Might tries to ask how he is still alive. All For One doesn't answer and says its a pointless question. He begins taunting All Might by saying society is beginning to turn on heroes, while sensing growing insecurity in the world due to the new heroes leader, Endeavor. All Might stands up in anger, while someone on a radio com asks him to please back away. He states he will not die and will not allow Tomura to kill him. All Might leaves while All For One continues to taunt him.

After leaving, he is in a car speaking with Naomasa. He then receives a text from Izuku with a picture of his provisional license saying "Thanks to you, I was able to take another step forward!", which causes All Might to smile, though he does not reply to the text.

That same night, he gets word that Izuku and Katsuki are fighting. He goes to stop the fight, but instead he stands back out of sight allowing the two boys to fight it out while eavesdropping on their conversation. After Katsuki pins Izuku down, he walks up to them. He apologizes to Katsuki for not realizing that he has been blaming himself for All Might's condition. Katsuki asks why All Might chose Izuku as his successor. He states that despite being powerless, he was more of a hero than anybody else on the day of the sludge villain attack, and he judged it was his responsibility to help Izuku stand in the arena, instead of Katsuki who was already standing in it.

Katsuki yells that he's weak and because of it, All Might became like he is. All Might goes up to Katsuki stating it was not his fault and apologizes for not realizing his pain sooner. He hugs Katsuki but is pushed away. He then gives advice to Katsuki and Izuku stating to be a hero one needs to both want to rescue and win, and if either is lacking, they will lose their sense of justice. He tells them if they can recognize each other and raise each other up, both of them can be heroes who both win and rescue. All Might then proceeds to tell Katsuki everything about One For All and how he passed it to Izuku. After hearing it, Katsuki realizes how dangerous of a secret it is and promises to not tell anyone.

Back at Heights Alliance, Shota restrains the tandem and punishes them for breaking the rules. All Might tries to calm him down by telling him that the fight was brought about due to Katsuki feeling guilty about his retirement. Although he understands the reason, Shota still refuses to let Izuku and Katsuki's transgression of fighting go by and gives them house arrest as an appropriate punishment.

Shie Hassaikai Arc
Several days later, after Shota Aizawa spoke to Class 1-A about Hero Work-Studies, Izuku reaches out to Gran Torino for a Work-Study opportunity. Gran Torino has to refuse because he's busy working with the Police and recommends him All Might's former sidekick, Sir Nighteye.

Izuku goes to All Might in the staff room and asks him to introduce him to Sir Nighteye for a Hero Work-Study. All Might refuses to help Izuku, much to his surprise. All Might says that there are three reasons for his decision: first, he was against letting the first years conduct Hero Work-Studies so early; second, he wants Izuku to focus on strengthening his Shoot Style; and third, he and Nighteye broke off their partnership not in the best way several years ago. Izuku tells All Might that if he is under the guidance of Nighteye, it will serve as a strong point of comparison to him and he must become stronger than anyone else.

All Might does not dislike Izuku's determination but he still will not be getting an introduction, not from him, so he calls Izuku and Mirio to the nap room to talk about a few things. All Might tells Izuku that Mirio is serving a Hero Work-Studies under Nighteye and asks Mirio if Izuku is fit to work under Nighteye. Mirio replies that there is no problem and considers Deku fit. However, Mirio does not understand why it is not him who presents Izuku to Nighteye since they were friends and allies and Nighteye still has great respect for him. All Might replies that he does not feel comfortable meeting Nighteye because he became exactly what Nighteye warned him about.

All Might allows Izuku to carry out his Work Studies under the guidance of Sir Nighteye. However, Izuku's first day is full of bitter revelations. Izuku discovers the truth about One For All, that he was not the right candidate to inherit it and that Mirio was the true successor of All Might as a Symbol of Peace. This makes Deku start to doubt himself. Nor does it help her that also on his first day he couldn't help a little girl called Eri, daughter of Overhaul, leader of the Shie Hassaikai, a Yakuza organization that Sir Nighteye was investigating.

Unable to keep going like this, Izuku goes out in search of All Might to ask him questions, finds him outside of U.A., jogging. Izuku asks him why he didn't tell him anything about Sir Nigheye knew about One For All and that Mirio was supposed to be the true inheritor of the Quirk. All Might states that there was no need to tell him everything, to which Izuku yells that there was and demands to know the whole truth. All Might decides to tell Izuku the truth but he mustn't regret it, to which Izuku replies that he won't.

All Might starts telling him that Sir Nighteye was his sidekick for years and that they formed a great team. But six years ago, after his fight against All For One they dissolved their partnership due to his injuries and because of the differences in their values. Nighteye warning him back then to stop continuing his hero duties due to his grievous injuries and look for a successor. He refused because that would generate a period of fear and chaos. Sir Nighteye revealed to him that the real reason he wanted Toshinori to stop is because he predicted his gruesome death at the hands of a villain in six to seven years.

After their argument, they went their separate ways. Nezu recommended Mirio Togata, but he ended up meeting Izuku before he met Mirio. All Might did not want to tell Izuku all of this since he was his fan and apologizes. Izuku is shocked and distraught with the truth All Might told him; not only he was never meant to be All Might's successor, but also that All Might has roughly a year to live.

All Might continues and tells him that when he met him, he considered him the perfect candidate to inherit the One For All. Toshinori told Nighteye about this, but Nighteye was vehemently against All Might's idea. Their heated debate further drove them apart, and Nighteye took it upon himself to cultivate Mirio, whom he believed to be the truly appropriate successor.

Izuku asks Toshinori if Nighteye's Foresight can be changed. However, Toshinori's answer crushes Izuku's hopes; there is a margin of error of his estimation, but nothing can change the future he sees in his Foresight. Toshinori tells Izuku that after he had accepted his inevitable death with ease and because the goal was in sight, he ran full speed towards it. Toshinori reveals that the goal was his final confrontation with All For One at Kamino and that he planned on dying there.

However, Izuku was there, a timid Quirkless boy who day after day rose to meet his expectations. Izuku's determination and his mother's encouragement gave him the will to twist Nighteye's prediction and try to stay alive to see the boy grow into a hero worthy of being the Symbol of Peace. Izuku promises All Might that they will defy fate together.

During the Shie Hassaikai Raid, Sir Nighteye is fatally wounded by Overhaul. Sir Nighteye's wounds are too serious and the doctors tell that he won't last. Bubble Girl, one of Sir Nighteye's sidekicks, calls All Might to see him at his last moments. Izuku and Mirio are also there. Nighteye remarks on how it fitting it is for his mentor to visit him one last time on his deathbed. All Might laments on not visiting him before and begs his old friend to pull through so he could make amends.

Izuku begs Sir Nighteye to live as Sir Nighteye claims that he does not blame All Might and only wanted him to be happy and is fine with All Might fighting against fate. Sir Nighteye has wanted to change All Might's future where he is murdered but could not find any answers. However, Izuku showed him a way. Sir Nighteye hypothesizes that everyone's wishes for a better future changed the outcome. All Might and Izuku grieve as Sir Nighteye is satisfied with his changed views of the future never being certain.

In his last moments, Sir Nighteye says goodbye to everyone, tells All Might and Deku that he is thankful for having met them, and uses Foresight one last time to look into Mirio's future, assuring him that he will become an outstanding hero. Sir Nighteye passes away peacefully after telling everyone to keep smiling, as society needs smiles and laughs to bring about a brighter future.

With the last words spoken, Izuku, Mirio, and All Might are left crying at the loss of their beloved Sir Nighteye.

Remedial Course Arc
Because Shota must take care of Eri, Toshinoi becomes the substitute for Eraser Head for Katsuki and Shoto's Provisional Hero License Course, with Present Mic as his bodyguard. Before the exam starts Endeavor enters thanking All Might for looking after his son Shoto, he then demands to have a proper chat with All Might.

All Might alongside Endeavor and Present Mic enter the room where the training was being held, and Endeavor shouts Shoto's name to encourage him and gains the attention of everyone there. Everyone in the room were merely curious as to why he was there, but they grew ecstatic upon noticing All Might with him.

While the students have the trial to take care of a group of unruly children from Masegaki, the former and the new number 1 heroes have a conversation. Endeavor asks the former Number One Hero what the Symbol Of Peace is, telling him about how he became the Number Two Hero at the young age of 20 but immediately knew he would never beat All Might, which is why he entrusted everything with Shoto.

In response, All Might states that he always believed that the country needed a symbol to be their beacon of light, and in doing so he ignored the people around him, such as his former sidekick. All Might tells Endeavor that he knows his struggle of filling in his spot as the Number One Hero and tells him he does not need to follow in his footsteps to become the same symbol but find his own way of doing things instead.

Both heroes witness the success that the students have had with children, All Might tells Endeavor that the reason to be strong is very simple, and believes Endeavor knows the answer to that simple question. After the trial ends, he talks with the Shiketsu High School teacher about the U.A. High School and the Shiketsu to start working together in order to stop the League of Villains.

At the beginning of October, All Might accompanies the Work studies group to attend the funeral of Mirai Sakaki. Toshinori pays his respects to his former sidekick and friend, saying goodbye definitively to him, before returning with his obligations.

U.A. School Festival Arc
Per Izuku's request, Toshinori meets with him at the school's break room. After discussing the preparations for the U.A. School Festival, Toshinori asks Izuku why he wanted to meet at such a busy time to which the latter expresses his desire to learn long-range attacks. Izuku frustratingly tells Toshinori that even with his power at 20% he could not hold his own against Overhaul, and had it not been for Eri he would not have been able to win.

Understanding his problem, Toshinori tells Izuku that he should use ranged combat as well, and both go to the U.A's school grounds forest sector, Toshinori asks Izuku to use One For All 20%. Izuku activates One For All 20% and even though it starts hurting him, Toshinori tells Izuku to remain in position and unleash his attack. Izuku jumps up and kicks, which releases a monstrous burst of wind. Toshinori congratulates him and was going to teach Izuku to properly unleash wind pressure after his overall power limit passed 15%.

Toshinori affirms that Izuku can unleash wind pressure without his body breaking, and tells him that he must take a moment to rethink through his journey. Izuku does so. All Might states that, once Izuku's maximum limit had passed 15%, he had wanted to tell him that he was not always bringing out 100%. Izuku is struck with realization, that if All Might had continuously moved at 100%, he would have caused a devastating windstorm in the surrounding area. Izuku realizes that he cannot move long at 20%, and surmises that he must use One For All 20% in one area, which not only releases a decent amount of power but prevents his body from becoming completely immobilized. Toshinori advises that Izuku needs much subtler control than he has exercised now. An encouraged Izuku sees that he needs to refine his body parts that require the most motion.

The days of the week go by, and while Deku practices with his classmates for the School Festival dance show, he also trains to be able to perform long-range attacks with Toshinori Yagi. As Toshinori advises Izuku to avoid internal bleeding, Izuku has trouble keeping control of the wind pressure at critical moments and asks Toshinori for his advice, but he does not have any helpful suggestions since he was able to use One For All freely from the very beginning.

Then, Toshinori hears a noise behind him and catch a flying ball that was flying at him and Deku from behind without turning around. Mei Hatsume appears and reveals that she is there testing her inventions. Mei notices and informs Izuku that he will soon have the support item he has requested. As Mei leaves, Izuku tells Toshinori that the item he requested has to do with a new technique he has developed. Toshinori shocks Izuku with the revelation that he once used support items as well, but the equipment was too bulky for him and was not effective in close range combat. While he finds reinforcing oneself with items to be a good strategy, Toshinori reminds Izuku not to rely solely on support items too much.

The day of the festival has arrived. At 6:30 p.m., Izuku is training with Toshinori when a Mei shows up and gives him the support equipment he requested: a pair of gloves. Toshinori notes that back in his day his support equipment was quite bulky and is surprised that support equipment nowadays are quite compact. Mei gives Izuku the manual for the gloves and runs off; Toshinori decides that Izuku should try out the gloves, with which Izuku agrees.

A few hours before the school festival begins, Izuku has to go out running errands, meeting Gentle Criminal and La Brava on the way, two minor villains who wanted to infiltrate the campus. Izuku manages to stop them but the combat delays his lap a lot, but fortunately, he arrives in time to participate in the performance of Class 1-A, which is a success.

After finishing the show, Toshinori scolds Izuku for worrying everyone with his delay, for which Izuku apologizes as well as for the scuffle between him and Gentle Criminal. Toshinori is well aware of the situation from Ryo Inui and Ectoplasm. Although Ryo praises Izuku for not getting injured and for preventing the festival from being canceled, he scolds Izuku for not contacting the heroes to take charge of the situation.

Izuku acknowledges his fault which satisfies Ryo who sends Izuku flying towards the festival, telling him to have fun. Toshinori thanks Ryo who gets over-excited and starts playfully attacking Toshinori.

Pro Hero Arc
At U.A., All Might watches a report of a Nomu attack in the Teachers Lounge along other members of the U.A. Staff. He is horrified as it showed Endeavor being injured and overwhelmed by Hood's attack. All Might grabs his chest as he watches this scene, worried for his colleague.

Toshinori then watches as Endeavor regains his strength and defeats the Nomu by incinerating it with Prominence Burn. He then witnesses Endeavor using a pose similar to the one he made to symbolize his victory against All For One, and is shocked by this feat.

Joint Training Arc
One night, Izuku experiences a dream where the First User interacts with him and shared his memories. This dream ends when One For All managed to activate on its own, causing a great mess in Izuku's room and shattering his window.

The next morning, Izuku tells All Might everything that happened about his dream, which leaves him surprised. All Might tells Izuku that he also experienced similar visions. His master told him that they are vestigial remnants of the prior generations of One For All rather than simple dreams. However, he tells Izuku that he is the first user of One For All being able to interact with the vestiges. All Might tells Izuku that he truly does not understand what happened that well and they should search for answers together.

Izuku goes to the industrial training area, where Classes 1-A and 1-B are about to compete against each other in a Joint Training Battle. Joining them is Hitoshi, who is eager to enter the Hero Course. The teams and the order of participation are organized by lots. All Might and Midnight come to spectate the battles.

After round one, in which Hitoshi participates, Shota asks All Might what he thinks about Hitoshi since this exercise is his test to get into the hero course. All Might claims that Hitoshi showed great potential and expects the next set to be even more passionate.

After round two, All Might asks Izuku if he has felt anything weird since his dream about the previous users of One For All. Izuku replies that he hasn't, and All Might tells him that he will ask Gran Torino if Nana ever mentioned anything to him about similar visions. All Might tells Izuku to be careful in his match against Hitoshi, as Hitoshi seems to be a piece of the puzzle, as far as the visions are concerned.

Suddenly, Katsuki appears and ask them were just talking about, reminding the two that he is also in on their secret. They tell Katsuki that One For All managed to activate on its own when Izuku had his dream, which surprises him. Katsuki proceeds to berate Izuku, asking him when he will make One For All his own. All Might wonders if this is Katsuki simply showing his own type of regard for Izuku.

When Class 1-A, under Katsuki's command, achieves victory in round four, All Might confronts Katsuki and commends him on a great job well done. Katsuki brushes him off and Izuku congratulates him next. Katsuki yells at him out of reflex and then reminds Izuku that he's getting stronger. Izuku claims he'll still surpass Katsuki, annoying him. All Might claims Izuku has a good friend in Katsuki outside of his vulgar language.

The fifth and final match starts, where Izuku along with Ochaco, Mina and Mineta, faces the Class 1-B team, in which Hitoshi is one of the teammates. All Might receives a call and walks over to a private area to speak to Gran Torino. Gran Torino tells him about Nana's dream about One For All, the old hero mentions that around the time when Nana inherited One For All, she had a dream about a strange figure shrouded in dark fog telling her "It's not time yet…".

While the conservation goes on, something goes off with Izuku's Quirk, as dark energy begins to emanate from his body in strength, destroying his equipment in the process, and goes on a rampage. A horrified All Might tells Shota and Vlad King to cancel the match before anyone becomes gravely injured in the process. However, before they could intervene, thanks to the intervention of Ochaco and the power of Hitoshi, they managed to get Deku to regain control.

The fifth round continues under the watch of Eraser Head, Vlad King, and All Might. Vlad expresses shock as Shota decides to let the match go on, despite both teachers witnessing Izuku's Quirk going berserk, but Shota explains that he'll keep a close eye on Izuku just in case if he loses control of his power once again. He also notes that Hitoshi's brainwashing ability has managed to prevent it from injuring the participants. All Might questions Shota's decision, only for the latter to respond that he believes that all combatants still feel determined to fight out till their very last breath.

The fifth round ends with victory for Deku's team, and having obtained more victories than Class 1-B, Class 1-A is declared the winner of the Joint Training Battle.

After the Joint Exercise, Izuku, All Might, and Katsuki have a conversation about the latest events and revelations related to the All For One. It turns out that the black tendrils that Deku manifested are actually the Quirk of one of the predecessors, known as Blackwhip, and that Deku will manifest the Quirks of the previous One For All users. When Katsuki asks All Might about what he knows about the interactions of the predecessors and Deku having a new Quirk, he admits that everything is new to him and that he has no idea about the whole thing.

The conversation ends, when Katsuki asks if this turn of events has anything to do with All For One, explaining that it would make sense as he was the person who created One For All in the first place and he can also possess multiple Quirks. While All Might does not disregard that theory, he also states that it was the last thing he wanted to think of.

Around 7:00 PM in the evening, Izuku and Katsuki engage in a sparring match at Gym Gamma. Katsuki tries to activate the Blackwhip by putting Izuku in a dangerous situation, believing that it would activate it, but Deku reveals that it apparently can't be unlocked as of now. All Might immediately tells the two to halt the match, seeing that it does not work. Without knowing what to do, they decide to return to their rooms.

Meta Liberation Army Arc
In early December, All Might accompanies Shoto and Katsuki for the final test to obtain their Provisional Hero License. They eventually succeeded, and on their return to the U.A. they witness a villain attack. All Might chases after Shoto and Katsuki as they confront a group of villains going on a theft spree.

While Shoto and Katsuki battle the villains, All Might assists in evacuating the bystanders. One of the bystanders stops to film the fight, while unaware that a light post is about to fall on her. All Might notices and is able to push her out of the way at the last moment thanks to one of Katsuki's explosions. He then gets berated by Katsuki for being careless.

After the villains are defeated, All Might is accompanied by the Pro Hero, Slidin' Go, who praises the duo for a job well done. All Might also congratulates the duo for doing a great job.

My Hero Academia: Heroes: Rising
During fall, Toshinori and principal Nezu met with Yokumiru Mera at U.A. High School, who explained to them about the Hero Public Safety Commission's new program, the Hero Work Recommendation Project, to help to train the new generation of Heroes due All Might retirement.

Weeks go by, and shortly after winter begins, Class 1-A is sent to Nabu Island, a remote place in southern Japan. As the Class 1-A members are helping around the island, at U.A. High School All Might worries about whether they will be okay. Shota assures Toshinori that he should not be concerned, as Nabu Island is a quiet place where there have been no incidents involving villains in the past thirty years, and the students should be relatively safe from any significant threats.

Unfortunately, the island is attacked by the villain Nine and his gang, although the students managed to defeat them and send a S.O.S. Shortly after Class-1-A emerged victorious over the threat, a field force of professional heroes and the military arrived on Nabu Island. Toshinori helps the wounded Izuku and Katsuki, who had barely managed to defeat Nine. A barely conscious Izuku tearfully apologizes to Toshinori for giving One For All to Katsuki because he had no other choice if he wanted to protect the people on the island before losing consciousness.

Toshinori forgives Izuku, but is left surprised when he sees One For All still retained inside of Izuku. At first, he theorized that Katsuki must've lost consciousness before the transfer could be completed, but then theorized that One For All must've kept itself inside of Izuku for his willingness to risk himself to protect the innocent even if it means losing One For All. Tearfully, Toshinori thanks the previous users of One For All and his master, Nana Shimura.

After helping with the repairs, the Hero Public Safety Commission suspends the Hero Work Recommendation Project, so everyone returns to U.A.

Endeavor Agency Arc
At the end of December, Toshinori appears more skeletal than usual because he hasn't slept in a few days, collecting all the information he could find about the previous One For All inheritors and their Quirks to help Izuku. Nezu visits him to inform him that the next round of work studies will begin soon.

A few days later, Nezu talks to All Might and detective Naomasa through a video call. They talk about the fact that since all the students moved into Heights Alliance four months ago, they have been being watched to discover the League's spy, but in all that time no one has shown signs of being the spy, so it seems that the traitor is not one of them. All Might tells Nezu that all students of the Hero course are true heroes and none of them is the traitor, to which Nezu replies he knows that. Then, Nezu asks All Might if he will return to the U.A. that day. All Might tells him that it is unlikely since he is very busy unless something happens to Izuku. Nezu reassures him by telling him that he apparently has forgotten that it is Christmas.

Subsequently, Izuku and Katsuki talk with Toshinori that they have accepted a proposal from Shoto to do their Hero Work-Studies with Endeavor. Toshinori thinks it's an excellent idea. When Izuku asks him about his training with the One For All, he replies that there should be no problems because as long he has mastered the image of "locking" and "unlocking", All Might he doesn't expect that he will experience more outbursts. As for Katsuki, All Might tells him that it will benefit him to work with Endeavor since both are very similar.

Paranormal Liberation War Arc
Winter break ends and students return to the U.A. High School. Class 1-A head to Ground Alpha to show how much they have improved with their skills and Quirks during the Hero Work-Studies. Because Shota Aizawa has to attend an emergency, Toshinori replaces him. He welcomes Class 1-A students at Ground Alpha, making cotton candy to make a joke on his catchphrase, which doesn't win over the students.

Class 1-A begins the training, battling Villain bots to showcasing their newfound abilities. Finally, it's Katsuki and Izuku's turn to show off what they learned working for Endeavor at his agency. Toshinori is especially glad about Izuku showing his improved control over Blackwhip. All Might recalls some of his interactions with him, holding back tears, but proudly looking on as he realizes that Izuku no longer needs his approval, as he's outgrown the need for it. All Might concludes the class, revealing that everything was recorded for Shota Aizawa to watch later, and encourages the students to keep working hard at their work studies.

Later, in the Teachers Lounge, All Might meets with Izuku and Katsuki, congratulating the two on their improvements, much to Izuku's delight and Katsuki's annoyance. All Might then places a notebook on the table that contains his research into the Quirks of the past successors of One For All. He reveals he couldn't find anything on the 2nd and 3rd users due to the era they existed in and the multifaceted nature of the Quirk. All Might asks Izuku if he made contact with the other users, to which he says no.

During the conversation about the previous heirs, Toshinori reveals that they were heroes who did not have particularly powerful Quirks, as All For One hunted down the strongest. Also, the concept of a "One for All successor" was not implemented until Nana Shimura chose him. Until then, the heirs fought All For One and got themselves killed for it at relatively young ages, and they simply entrusted One for All to their closest ally to keep fighting, until one day the Quirk grow powerful enough to defeat All for One. Katsuki then asks what the next Quirk Izuku will get, to which Toshinori says it'll be Nana's Quirk, which is called Float.

At night, he is sitting outside Heights Alliance, when Shota approaches him and asking him what he's doing, to which All Might says he isn't doing much. He asks about Eri to which Shota tells him she's asleep and he'll start training her this week. All Might offers his help, to which Shota appreciates. He then asks what's bothering All Might, to which he says that while he has decided to live, he can't help but feel powerless when he sees how much they've developed.

Shota tells him that because he bore the title of Symbol of Peace for so long, it's hard for him to accept that there are so many other things he can do for the students, such as being there for them, and to keep being the person he knows he is. All Might accepts the advice while asking what Shota wanted, to which he tells him that Naomasa sent a message to him asking for him to delay his meeting with Stain.

All Might is later seen watching the news about the destruction of Jaku City with Eri. After the Paranormal Liberation War, All Might is seen in the hospital, holding the hand of an unconscious Izuku, who has remained in a coma for two days due to the extent of his injuries.

While sitting with him, Toshinori is able to sense One For All within Izuku, albeit barely. Inside Izuku's mind, he meets the vestiges of the previous One For All users; among them is Toshinori's vestige, who unlike the others, has flames covering his entire body, masking his true appearance. While conversing with Izuku, they reveal the dangerous side-effect of One For All shortening the user's lifespan if they already have a Quirk, something they were only able to learn thanks to the research Toshinori conducted and the fact that Toshinori had a much longer lifespan. This information was passed to the other users through his vestige, and the first user reveals that unlike the rest of them, since Toshinori doesn't have a Quirk and therefore can't have a Quirk Factor imprinted into One For All, he managed to actually imbue One For All with a true piece of his consciousness.

Toshinori continues to take care of Deku until Hawks and Best Jeanist arrive and ask to speak to him. Haks explains that they want to know what the connection is between Izuku and All For One because the media heard that the villain was after something known as One For All and Endeavor informed them that during the war Tomura Shigaraki was targeting Izuku. With the current crisis, they need to know the truth. Recognizing that there is no point in continuing to hide the secret of One For All, Toshinori takes them somewhere to tell them everything.

Days later, Izuku regains consciousness and is visited by his mother. A medic informs them that since Izuku's body has largely been able to adapt to his Quirk, his injuries weren't that serious. Despite that, he warns that his limbs may still be immobilized, so he advises her to be careful.

After the doctor leaves, Inko demands an explanation and Toshinori and Izuku decide to tell him the whole truth about the One For All. This leaves Inko dumbfounded, wondering what will become of his son knowing that the villains will go after him. Toshinori tells her that they are making arrangements to protect him at U.A. but Izuku announces he won't be returning, since he does not want to put the people he cares in danger. He hugs his mother and tries to reassure her as Inko breaks down in tears, promising to return home to her.

Barely able to contain her tears, Toshinori remembers when he bowed to her at their home and declares that he knows he can't stop Izuku from going, so he offers to join him. He contacts Best Jeanist informing him of this turn of events, who accepts it, saying that he may be the only one who can determine Tomura's location after thinking of using him as the focal point of their efforts, so they will follow in his wake while maintaining a safe distance.

Tartarus Escapees Arc
By the start of what would be Izuku's second year in April, they leaves U.A. High., they leave U.A. accompanied by Endeavor, Hawks and Best Jeanist. The plan of the five is to use Izuku as bait to lure out the League of Villains and determine Tomura's location, while they follow suit maintaining a safe distance. This plan leads them to face a multitude of villains in order to find any clue about All For One and Tomura. A newly modified Izuku and All Might head off for their team-up with the Top 3 Heroes. To help his protégé and prevent further arm damage when fighting, Toshinori ordered a new support item for Izuku, called Mid-Gauntlets, from America before the borders closed.

After defeating and sending Muscular to prison, Izuku meets Toshinori in an alleyway, who was waiting for him by his car, Hercules. Toshinori asks him if he is hurt, and Izuku reassures him saying that he is fine and that the Mid-Gauntlets were very useful. Toshinori reminds him that the item is still a prototype and they were made for endurance; they will reinforce his body but they can't handle 100% output, therefore he can't go overboard until his rematch.

All Might's phone rings, picking it up to hear Hawks speaking to him while he, Endeavor, and Best Jeanist contain a villain. Hawks asks how Izuku is doing and All Might reports he is fine, but he immediately departs, having received another warning from Danger Sense. Hawks surmises he is worried about putting anyone else's lives in danger, adding that while they could potentially keep him completely isolated to prepare for what is to come, knowing the capacity of power the ones who attacked Tartarus possess, it will be all over if they come well prepared.

Because of this, following Izuku's idea of actively seeking out their enemy will raise the odds of their victory. Hawks knows how tough a position this is for Toshinori, and that even though he's worried, the best they can do right now is support him.

During a stormy night, after Izuku saved the life of a woman who was being attacked by mistaking her for a villain, Toshinori arrives on the scene to help. Izuku asks him to take her to the shelter, but not before he hands him a lunch box to eat which he thanks him for.

Later, while following Izuku from a safe distance, Toshinori thinks that Izuku is trying too hard at his task without hardly resting, and this reminds him of the conversation he had with his sidekick Sir Nighteye when he was convalescing from his injuries from his combat against All For One, when he wanted him to retire from hero work and take a break now and then. This memory is interrupted when he realizes Deku's GPS signal has disappeared. Then, a grenade is thrown at his car and explodes. Fortunately, the Hercule manages to withstand the explosion and Toshinori is unscathed.

Two villains appear ready to throw flaming spears at him, and Toshinori instantly realizes that this is not an ordinary attack but with clear intentions to kill him. All Might grabs a spare phone and alerts the rest of his team that the villains are trying to separate them from Deku, who must be facing off against a villain. Toshinori manages to get out of the car with a suitcase before the villains destroy it with their weapons.

The villains are surprised to see All Might, but don't stand down since he isn't the same as he was before, saying the real All Might died a long time ago. However, when he demands they stand aside, the villains start shivering in fear when They feel his aura of intimidation. Toshinori remembers the promise he made to Inko as he tells the villains that Deku is bearing more of a burden than he himself ever did yet he still idolizes him, and he yells that the day anything happens to him is the day he dies.

While he is busy dealing with this two villains, Deku confronted Lady Nagant, a villain sent specifically by All For One to capture him, but managed to defeat her, and as a preventive measure, AFO implanted in her a Quirk of immolation that made her explode. Thanks to the previous call from All Might, Endeavor and Hawks manage to reach Deku and take care of the charred Lady Nagant, who is still alive. Minutes later, All Might finally arrives asking Deku if he is okay and Endeavor ensure him that everything is under control.
