Template:Toshinori Synopsis/Final Act

Dark Hero Arc
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 her the whole truth about 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.

By the start of what would be Izuku's second year in April, he leaves U.A. High, with All Might accompanying him, after secretly leaving behind letters to Class 1-A explaining everything about One For All and his connection to the villains. The plan is for Endeavor, Hawks, and Best Jeanist 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. To help his protégé and prevent further arm damage when fighting, All Might ordered a new support item for Izuku, called the Mid-Gauntlets, from America before the borders closed.

After defeating and sending Muscular to prison, Izuku meets All Might in an alleyway, who was waiting for him by his car, Hercules. All Might asks him if he is hurt, and Izuku reassures him saying that he is fine and that the Mid-Gauntlets were very useful. All Might 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 All Might, 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 people mistaking her for a villain, All Might 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, All Might 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 Izuku's GPS signal has disappeared. Then, a grenade is thrown at his car and explodes. Fortunately, Hercules manages to withstand the explosion and All Might is unscathed.

Two villains appear ready to throw flaming spears at him, and All Might 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 Izuku, who must be facing off against a villain. All Might 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 immense aura of intimidation. All Might 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, Izuku confronted Lady Nagant, a villain sent specifically by All For One to capture him, but managed to defeat her. As a preventive measure, All For One 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 Izuku and take care of the charred Lady Nagant, who is still alive. Minutes later, All Might finally arrives asking Izuku if he is okay and Endeavor ensures him that everything is under control.

Sometime later, Izuku defeats another assassin sent by All For One and immediately tells All Might that he knew nothing and to be careful in case he is rigged to explode. All Might yells to Izuku to stop so he can give him some more food, but Izuku tells All Might that he doesn't need to follow him anymore, saying that he is fine on his own now. All Might tries to speak but Izuku claims he can practically move at 100% without injury just like he could, so he shouldn't worry about him. He wants to tell him to rest, but he can't as Izuku leaves, and All Might trips as he tries to reach out to him.

Eventually, Izuku is cornered by Class 1-A and taken by to U.A. for some well-needed rest. However, instead of checking up on him, still depressed about him leaving him behind, All Might returns to Kamino, in the aftermath of his battle with Class 1-A, intending to check in on the anti-hero supporters who refused to evacuate, while still thinking about being unable to help Izuku. Looking at the statue of his former self, he berates himself for doing nothing and just dragging everyone down. Stain then suddenly appears above him, holding his sword near his neck and demanding he take back his slam against All Might.

All Might realized it is the Hero Killer and notes how Stain never went after him when he was active and they didn't get to have their meeting till now, but the Hero Killer becomes confused, leading All Might to clarify who he is by quickly transforms into his muscle form to prove it, but Stain reacts in disgust, refusing to believe that was him just now, calling him a sham and why he presumes to call himself a "hero."

All Might responds back to Stain's claims in agreement, explaining how he couldn't handle the uneasiness of the world, and despite being powerless, he wanted to make the world a better place, but now he's reached his end point. With so much chaos in the world, and unable to protect the student he promised he would, he feels like he's gotten further away from heroism than anyone.

Stain leaps forward and pulls All Might back behind an ice block, before pointing him toward the statue. The two see a girl pulling down the "I Am Not Here" sign off of it, which Stain says she has been coming by to clean the statue from the vandalism every day. All Might is confused why she would put herself in danger just for that, until Stain reveals she is the last person All Might saved: the girl from the Kamino Incident.

Stain exclaims that what All Might did as a hero had nothing to do with his Quirk, but that he always kept a smile on his face and did everything he could to help people. That the embers of inspiration he left behind continue to burn within those who followed him, and have now started to form a great fire, so they all must continue to stoke the flame so that it won't die.

After Stain reveals he knew about what happened regarding his true state, he tells him that if he is a true hero, to make use of his information from Tartarus, throwing him a knife and several pieces of paper, as well as telling him to end "the man who murdered 40 heroes" to fix this society, before walking away.

Shortly after this, All Might returns back to Heights Alliance, where Class 1-A has just finished bathing down Izuku. He busts into the dorm and apologizes himself to Izuku for not helping him enough despite his protests, but Izuku apologizes back for abandoning him too. The other kids demand an apology for leaving them abruptly as All Might says that the decisive battle is drawing near. He tells everyone that he has acquired some new information that will help them, thinking back to Stain's words, and that he has decided to continue supporting everyone even though he is Quirkless. Izuku speaks up and tells All Might that the food he made for him gave him strength, and chalked his hardships to not having him at all.

All Might heads back out to meet up with Naomasa, after giving them the data Stain had given him. Naomasa reveals that since Tartarus' systems are cut off from the outside world, they would've had no way of getting this data normally, and that it contains the cause of the system shutdown, which was "Tomura" and All For One's constant blasts of Radio Waves inside and out.

Sansa suggests that this is because All For One was synchronized with the vestige within Tomura, however All Might reveals that the communication isn't a two-way channel. Just like with his vestige within One For All, while the vestige has access to all his current thoughts, All Might himself has no connection to the vestige itself, at least until he was able to make contact with Izuku back at the Hospital. Because of this, All Might believes that even All For One wouldn't be able to have such direct control over the vestige from so far away.

Naomasa then says that the two All For One's were able to communicate through the Radio Waves Quirks, and that the recorded waveforms on the data disk resemble a conversation that says: "Make him complete in 38 days." The revelation shocks Sansa, as Central Hospital's research stated it was 2 months till he was completed, but All Might says it's possible he rigged the results as a bluff, and that if they are to take their conversation as the truth, Tomura will be complete in 3 days.

Star and Stripe Arc
With Tomura's near impending completion, All Might calls in to the foreign heroes for assistance. While the rest are unsure, America's No. 1 Hero Star and Stripe, who considers All Might her spiritual master, makes her way over to help. During her impending arrival, she is ambushed by "Tomura", and in the aftermath of her battle, Star is killed. However, when "Tomura" stole her Quirk, she had turned it into a virus at the last minute, causing various of his Quirks to be destroyed and forcing him to flee.

Although All Might was currently at U.A. during all this, it wasn't until Star's American jet fighter pilots returned to tell him of her death. He lamented with sadness about wanting to see her again, however, the pilots tell him their fighter jets have a record of the battle, and were able to measure all of Tomura's bio-signatures, as well as every Quirk during the fight, providing the data to them to use, alongside the ones already being studied at Central Hospital.

U.A. Traitor Arc
The next day, two days after Izuku had returned to U.A., All Might informs Class 1-A that Tomura was supposed to have his body completed by the following day, but thanks to Star's New Order, it acted like a poison when Tomura stole it, eating away inside him and destroying a large number of his Quirks, with the class realizing now's their best chance to take him out. He continues that the remaining Heroes have been continuing the mass evacuation effort and hunting the remaining Villains, and reminding them that due to how unpredictable All For One is, all out war is inevitable.

He reminds them of their current targets: Tomura, All For One in his original body, Dabi, Himiko Toga, the remaining six Near High-End Nomu, the remnants of the Paranormal Liberation Front, and the remaining escaped convicts, also including that they'll be likely to amass more allies too. All Might continues that while less than half of their heroes remain, it is thanks to Star's sacrifice that they have a chance to use this time for everyone to grow even a little bit stronger.

In response, Katsuki yells at All Might that they've already been doing this. Class 1-A reveal that since the War, they've continued their training with the Wild, Wild Pussycats, all with the intention to fight alongside Izuku until Tomura is defeated. The rest of the class each respond with enthusiasm as they all prepare to go out and train. All Might watches on, thinking about how the "zygotes" from the first day of class have hatched brilliantly into fledgling heroes. He thinks about how All For One has made a foolish mistake underestimating them, and that Class 1-A is a mighty force to behold.

Unfortunately, his spirits were shattered when he and the other U.A. staff are informed of U.A.'s traitor being captured by Izuku and Toru, revealing to be Yuga Aoyama. In the U.A. A.V. Room, the Aoyama Family are interrogated by All Might, Detective Naomasa, and the U.A. staff, learning Yuga was Quirkless and received his Quirk about 10 years ago from All For One, so his family was forced into his debt.

After interrogating them on information regarding All For One, Izuku speaks up as he recognized Yuga's troublesome situation and had no malicious intentions in his actions, so wants him to help them and prove he can still be a hero. The rest of the class believes this as meaning they can use Yuga to deceive All For One, but Naomasa reminds them that it is still very unlikely that could work. Just then, Shota Aizawa, listening in on a tablet, informs everyone that he has an idea, which they all listen to after covering the Aoyama Family's ears. Nezu says that it seems possible, and All Might adds that it'll be up to how well "he" can handle it, as Naomasa escorts the Aoyama Family back to their HQ, telling everyone not to say a word to anyone else about the plan.

With the plan preparing to go into motion, and Class 1-A heading out into the streets to hunt down the villains, All Might and Hawks form the "Counter-Force", including Ragdoll, the Police Force, and Star and Stripes' American military task force. At the start of their meeting, he informs everyone that after deeming them all trustworthy, and with the other big Heroes currently out in the field, they'll be keeping their current circle small to detail the classified information.

All Might demonstrates their scenario by placing tiny refrigerator buttons of the villains on a whiteboard, stating that whether they're going for Plan A or B, what they must do no matter what is to split them up. He further elaborates that the only way they can hope to achieve total victory is by isolating all of the villains that are deemed a major threat: separating each of the League's major operatives, luring them out individually, and defeating them one by one.

Several men say it's easier said than done, with All Might responding they need to have a strategy to make it happen, which Naomasa figures is Yuga. He adds that while he does sympathize with his situation, considering he still turned his back on society, from his position he still has to proceed with caution. All Might chooses to believe in Yuga, and he already believes in his teacher, Shota.

Final War Arc
After the conclusion of the meeting, All Might, Naomasa, and Nezu visit Class 1-A to explain the plans to deceive All For One. They remind them how unlikely it is they'll be able to track them down in their search, however, this works to their benefit as it allows them to draw him out by getting him to loosen up. Naomasa explains how they assume that All For One is using Search to monitor everyone, and everything they've done since Izuku returned will make him believe that they're being exhausted, which will allow them to catch him off guard, and utilize Shota's plan of having Yuga choose the location to lure him out.

Theorizing that All For One has a way of determining whether people are lying or not, in order for the plan to take effect, All Might has recruited Hitoshi Shinso, to the class' excitement. Hitoshi explains that he had to train hard to keep up with everyone, so managed to push through the limits of his Quirk to allow him to get his brainwashed targets to talk, so their plan is to make Yuga and his parents talk so that their motives and emotions won't come into play at all.

Sometime later, All Might watches as Hitoshi brainwashes the Aoyama Family as they are in contact with All For One, giving him Yuga's number, followed by a brainwashed Yuga giving All For One their meet-up location, a parking lot on the outskirts of the U.A. "Troy" dormitory.

When the day finally arrives, All Might and the Counter-Force observe from Central Hospital, waiting patiently for Izuku to make contact with Yuga who was recently released from his "lawyers", anticipating All For One to finally reveal himself after months of hiding without a single trace. With One For All in his reach, All For One summons an army of villains, intending to end it all here so he can get One For All, using Search to confirm none of the Heroes are anywhere near.

However, it turns out the other part of their plan to catch him off guard was to utilize Neito Monoma to Copy Kurogiri's Warp Gate, allowing them to teleport the heroes immediately onto the battlefield. Now that all the villains have been summoned in one place, All Might activates the Troy system, trapping all the villains in cages emerging from beneath the battlefield. All Might and Naomasa declare that even though they tried to bring him down once before and All Might's stomach was destroyed, they're still alive, and this time for sure they'll take him down. Neito summons several more Warp Gates around the cages, as the Heroes prepare to shove them all in, to split up the villains.

With nearly everyone warped, All Might orders Fat Gum in command to capture the remaining threats in the area and to watch over Yuga. All Might then tells Neito to regroup with Shota as now that the separation is successful, they can begin Phase 2.

As the battles continue, All Might receives word that Shoto has successfully defeated Dabi, getting emotional over his students' success. Naomasa reminds him they need to keep this up, as All Might proceeds to inform the rest of the battlefields of this status, giving them all a boost in motivation.
