Shota Aizawa/Synopsis

History
Sometime during his adolescent years, Shota attended U.A. High School with Present Mic. While picking their hero names, Shota was unable to decide so Hizashi chose the name "Eraser Head" for him.

Vigilante - My Hero Academia: Illegals
A year prior to starting his teaching career, Shota Aizawa was called into a meeting with Best Jeanist, Manual, Death Arms, Snipe, Thirteen, Endeavor, Air Jet, Midnight, Ingenium, and Gunhead. They met with an unnamed police officer to speak about the unwilling civilians injected with Trigger.

Afterwards, Midnight approached Eraser Head asking about where Present Mic was because he was supposed to be at the meeting. He explained that Present Mic had a cold and could not make it. Midnight scolded Eraser Head on his attire. In response, he teased her saying she should become a teacher or something if she likes counseling others so much. Much to his chagrin, she told him that's exactly what she plans on doing. Continuing on she revealed that principal Nezu personally requested her and that she would start next year at U.A. She detailed in constant innuendos her beliefs on teaching. Aizawa disagrees with her methods and as she begins a rebuttal; a Suicide Bomber attacked the police station.

Midnight returns to her conversation with Aizawa telling him he should also become a teacher because a wide variety of opinions and teaching styles is required to educate the youth. He asks if she is joking saying if he became a teacher that would be the epitome of irrational. The next day he was told Midnight had submitted a recommendation for him to the principal thus starting his career as a teacher.

Quirk Apprehension Test Arc
On the first day of the initial term for Class 1-A, Shota arrives outside the class in his sleeping bag. He overhears Ochaco Uraraka talking about making friends, and interrupts. He tells her she can go home if she is only at U.A. to make friends and promptly introduces himself as Class 1-A's homeroom teacher. He warns his students it took them eight seconds too long to get ready for class and says that rational students would be silent and seated already. Without any further interruption, Shota forgoes orientation and takes the class outside for the Quirk Apprehension Test

Shota instructs Katsuki Bakugo to throw a softball using his Quirk to preview the purpose of the test. The students get excited to use their Quirks but Shota warns them that the test is to gauge the students potential and the student who comes in last has none and will be expelled immediately.

He monitors the students as they go through each test in order to assess their room for growth. During the ball throw exercise, Shota stops Izuku from breaking himself by erasing his Quirk before he can throw the ball. Izuku recognizes his goggles and reveals to the class that Shota is the Pro Hero "Eraser Head". Shota claims that the judges should not have let Izuku enroll at U.A. because of his lack of control over his own Quirk. He tells Izuku that he cannot become a hero and instructs him to take his final throw.

Shota ponders whether Izuku will break himself or give up, but to his surprise, Izuku channels his Quirk into his finger and throws the ball over seven hundred meters. Izuku turns to his teacher and tells that him he belongs at U.A. Shota is deeply impressed and responds with a wide grin. Katsuki gets angry with Izuku and tries to attack him, but Shota stops him by using his Capturing Weapon. He warns Katsuki to stop wasting time and asks the next person to step up.

Following the conclusion of the fitness tests, Shota reveals the rankings to the class. Although Izuku comes in last place, Shota chooses not to expel him and tells the class he was lying. He writes it off as a logical deception to make sure each student did their best. As he leaves, Shota is confronted by All Might. All Might claims Shota was always planning to send someone home. he knows this because Shota's file in the teaching directory revealed he expelled his entire class before. Shota admits that Izuku does not have zero potential, but he can sense a connection between Izuku and All Might.

Unforeseen Simulation Joint Arc
Once the news about All Might becoming a teacher at U.A. breaks out, the media surrounds the entrance of the high school looking for a scoop. Shota confronts them himself, telling them to stop disturbing his students because All Might is not on campus. He returns to homeroom and informs Class 1-A that he has reviewed the results of combat training. First, he tells Katsuki that he is talented and not to sulk over his loss childishly so he does not waste his potential. Then he tells Izuku to work harder to gain control over his Quirk because it can be useful if he gets a grip on it.

Moving on to their next order of business, Shota tells the students they need to elect a class president. Tenya suggests the class holds an election and Shota tells them to have it done by the time he finishes his nap. Following the voting, Shota announces that Izuku is the president and Momo Yaoyorozu will be the deputy. After lunch, Izuku nominates Tenya for the job. Shota tells them to stop wasting time because he does not care who the president is.

Shota announces to the class that he, All Might and another instructor will host rescue training for the students at another facility. He tells them to get ready, but also to be mindful of their costumes. They take a bus to the Unforeseen Simulation Joint where Thirteen greets the class. He asks Thirteen where All Might is and she replies that he used up all his power and needs to rest before joining them.

Moments later, Shota feels an ominous presence as supervillains teleport inside the facility using a warp hole. He commands the students to stay back and remain together and tells Thirteen to protect them. The students are confused by the villain's arrival, so Shota makes it clear that they are real villains. He asks Denki Kaminari to use his Quirk to try and contact the school's main campus. Although Izuku expresses his doubt in his teacher's ability to fight all the villains alone, Eraserhead reassures the young man he has some tricks up his sleeve before he leaps into battle.

The villains firing squad takes aim at Shota, but he uses his Quirk to erase their powers and then knocks them out using his capturing weapon. The other villains soon recognize him as Eraserhead and reveal his quirk. One of them uses his Mutant Quirk to attack and is confident that Shota will not be able to erase it. Shota admits he cannot erase Mutant Quirks and instead subdues the villain using his restraining bonds. While fighting off the remaining villains, Shota notices Kurogiri got past him but cannot pursue him until he deals with the other criminals.

Continuing his brawl in the Central Plaza, Eraserhead is confronted by Tomura Shigaraki. He figures Tomura is the League of Villain's leader and manages to land an elbow strike. However, Tomura finds the weak point in Shota's erasures and manages to decay his elbow. Shota's hair moves out of his face while he is using it and this shows Tomura when he blinks. Shota punches Tomura away and backs away before he realizes the monstrous villain Nomu behind him.

Nomu crushes Shota with its overwhelming strength; as Izuku, Tsuyu and Minoru watch on hidden nearby. He tries to erase Nomu's Quirk, but realizes he has super strength without the need of one. Tomura eventually notices the students and attacks Tsuyu. Despite Nomu breaking many of Shota's bones, the teacher manages to erase Tomura's Quirk and saves Tsuyu from being disintegrated, as Tomura compliments his will. Nomu smashes Shota's head into the ground to subdue Shota, knocking him out. All Might arrives before the beast can kill him and saves him.

All Might gives Shota's unconscious body to the students and they carry him back to the entrance. When the battle against the League of Villains concludes, Shota is taken to be treated for his injuries by Recovery Girl and his condition worries the students.

U.A. Sports Festival Arc
The two days after the League of Villains assault, school resumes at U.A. Much to the surprise of his students, Shota returns to class covered in bandages. He tells them his well being is irrelevant and that their battle is not over yet. Afraid of possibly facing more villains, the class questions what Shota means. He replies that their fight is not over because the U.A. Sports Festival is approaching. Minoru and Denki question whether it is a good idea to hold the festival so soon after the villain attack. Shota explains that it is a show of good faith, and the festival is simply too important to cancel. Many pro-heroes will be in attendance and the students must keep training and make the best of their time in the upcoming Sports Festival.

Present Mic is able to convince Shota to commentate alongside him for the first years stage of the festival. When he asks Shota what competitors should look out for to start the obstacle race, Shota replies they need to watch doorway. Shoto freezes one of the giant robots at the first obstacle, Shota comments that his action was both offensive and defensive.

For the first leg of the race, all the pack leaders are from Class 1-A. Shota explains it is because his students have learned not to hesitate. The fear they felt facing real villains has helped them grow. They all know that they must act quickly if they want to stay alive. Present Mic mentions it is difficult for heroes to get popular without a flashy Quirk. Shota replies that he does not know what Hizashi means and calls him an idiot. Once the students reach the final obstacle, Shota tells Hizashi to calm down after he gets overzealous explaining the final obstacle. Izuku manages to clear the final leg of the race instantly, prompting Present Mic asks Shota what he is teaching them. Shota replies it has nothing to him. His students are powered by their own drive to succeed.

Just as the Cavalry Battle is about to begin, Hizashi wakes up Shota in preparation for the battle royale. Shota notices some very unexpected student combinations. When Team Todoroki manages to freeze many of the other teams, Shota notes that Shoto adjusted his strategy to have Denki immobilize them with his electricity because he was surprised when so many people avoided his ice during the race. Towards the end of the round Team Bakugo battles Team Monoma. Shota comments that although Neito Monoma had a good strategy, there was one thing they did not consider. Katsuki defeats Team Monoma by taking their remaining points. Team Monoma forgot to consider Katsuki's overwhelming tenacity. There is a break between the second round and the finals. Present Mic asks Shota to join him for lunch, but Shota takes a nap instead.

Everyone is surprised that the girls from Class 1-A are dressed as cheerleaders for the recreational games. When Nirengeki Shoda and Mashirao Ojiro elect to drop out of the finals, Shota points out that Midnight has the final say in the matter. During Izuku's match with Hitoshi Shinso, Shota talks about how the entrance exam isn't rational because students with a powerful Quirk like Hitoshi's get left out. He also ponders to himself about how Izuku would likely defeat Hitoshi in a fight without their Quirks. Once Izuku wins, Shota thinks about how Izuku is using every trick he has picked up so far to achieve victory. During the next match, Shota watches in pure awe as Shoto freezes Hanta in a giant ice prison.

Shota and Present Mic continue to announce the remaining matches. He is fairly annoyed when Mei Hatsume uses her match with Tenya as a commercial for her gadgets. Katsuki's match with Ochaco is ridiculed by Present Mic and the crowd because of Katsuki's brutality. When the crowd starts to boo him, Shota comes to the defense of his student. He clubs Present Mic and takes the mic to call out the Pro Hero who started the uproar against Katsuki. He tells the hero to go home and hang up his cape because Katsuki's fierceness is a show of respect to Ochaco. He cannot afford to let his guard down if he wants to defeat her. Ochaco eventually counters with a meteor shower of debris from the damage stage created by Katsuki's explosions. Shota had already noticed the debris hovering above the arena during the fight. While everyone else is in shock from her sudden comeback, Shota teases them for just noticing it.

Izuku faces Shoto in the first match of the second round an breaks all of his fingers to counter Shoto's ice. Shoto notices Izuku has lost some power but gained some control over his Quirk. Izuku is not fighting recklessly and says that he is simply doing whatever he can to win at his current skill level. Amazed by Izuku's resolve, Shota wonders what is driving Izuku to win despite his injuries. Izuku and Shoto's final clash destroys the stage. Shota explains the explosion is because the air was thoroughly cooled and then rapidly heated.

In the final match between Shoto and Katsuki, Shota notes that Katsuki's aptitude for combat is becoming more obvious with every battle. He also says that Shoto is not fighting poorly, he has simply lost his spark since fighting Izuku. Once the Sports Festival concludes, Shota meets his students back in their homeroom. They can next two days off from school to recuperate, and he will organize the offers from Pro Heroes for them after the break.

Vs. Hero Killer Arc
Classes resume at U.A. High two days after the Sports Festival. Shota returns to teach his homeroom class absent of his bandages. Tsuyu notes his healed injuries and he confirms Recovery Girl went overboard on his treatment. He announces that the class will be on hero informatics, worrying some of the students. Then he reveals that the students will need to formulate their hero names, much to their excitement. Shota orders them to calm down and then continues to explain that they will need to choose code names because of the Pro Hero draft nominations following the festival.

Normally U.A. students would not have to deal with the draft until their second or third year, but Class 1-A is an exception. Pro-Heroes are essentially investing in their potential, but any nominations can be rescinded if their interest in the student dies down before graduation. He reveals the total tally for the Class draft offers on the board. It is normally balanced between students, but this year there are many more nominations for Shoto and Katsuki compared to the rest of the students. Regardless of nominations or not, Class 1-A will all be interning with real Heroes. Although they got to fight against real villains, getting real field training will still but a fruitful experience. They will also need code names for the internship.

Midnight arrives to help evaluate the student's choices for their hero names. Shota explains that a heroes name represents them and is used to project their desired image. While Midnight helps the students, Shota takes a nap in his sleeping bag. After the students finish choosing their code names, Shota tells them they will spend one week interning with pro heroes. Students with nominations can choose from their offers while anyone who did not receive any will choose from forty hero agencies who have agreed to take students on. He gives them until the end of the week to make their choices and dismisses them from class.

In the staff room sometime after school, Shota looks over a few draft forms for those students who already chose where they want to intern. He is surprised to see that Tenya has chosen to intern in Hosu, Tokyo and nowhere else, figuring that he must have gotten better offers. Once the first day of the internships arrives, Shota meets Class 1-A at the train station where he instructs them to mind their manners with the heroes and reminds them to be responsible for their costumes.

While working with Present Mic in the staff room, they are both fairly annoyed by All Might's ringtone when he receives a call from Gran Torino. Shota even thinks to himself that All Might cannot possibly be serious. Following the end of the internships, Shota mentions during class that summer vacation is approaching and Class 1-A will be training at a lodge in the forest. The students are very excited about this news, but whoever does not pass the final exams at the end of the term will have to serve in remedial school instead.

Final Exams Arc
One week prior to the end of the term, Shota reminds his class to prepare both their minds and their bodies for the written and practical portions of the final exams. Later on, when Katsuki storms out of class, Shota notices that he has gotten worse. Shota oversees the written exams and meets with his class at the practical exam area after. Shota and several other teachers remind the students that it is possible to fail the practical. Some of the students have gathered information and know what to expect from the final. Denki and Mina are excited to say that they think they are fighting robots.

However, Nezu pops out of Shota's scarf and declares that the practical exam is being changed for various reasons. Students will now work in pairs to defeat one of the teachers before them. The pairs and opponents were already chosen by Shota. He announces that Shoto and Momo will face him, and Izuku and Katsuki have been paired together to fight All Might.

A few days before, Shota met with all the teachers to discuss changing the practical test. In order to reflect the current times where battles against villains look to intensify, they believe make the final exam more difficult is necessary. Shota noted that they can ignore complaints about student safety, as that is the reason they utilized robots in the past. With the final say, Nezu agrees they should change the test to teachers against pairs of students in order to make the students as strong as possible. Shota explained his reasoning for each of the matchups. He decided to take on Shoto and Momo himself to teach them not to rely so heavily on their Quirks. He also assigns Izuku and Katsuki to All Might in order to help mend their broken relationship.

All of the matchups between student pairs and teachers are revealed in order. The students must either capture the teachers using handcuffs are run away by getting through a designated escape gate within thirty minutes. This is to simulate situations where heroes must choose to fight or run to get help. Shota believes Izuku, Shoto, and Tenya know full well about needing to run and get help because of their interaction with the hero killer. Each teacher wears ultra compressed weights to give the students a handicap. Shota tells everyone it is time to begin and whoever is waiting to fight can watch in the monitoring room or strategize with their partners.

Eraserhead portrays the role of villain in the practical battle against Shoto and Momo. He finds them with their guard down and takes them by surprise by hanging by his scarf from telephone cables. He takes their Quirks from them and tells them to prioritize evasion. Shoto orders Momo to run for the gate while he swings and misses at his opponent.

Unimpressed with Shoto's plan, Eraserhead swiftly binds him using the capturing weapon and suspends him in mid-air from the cables. Shoto claims he can free himself at any moment, so Eraserhead responds by throwing caltrops beneath him and warning him to watch where he lands. Before departing to chase Momo, Eraserhead takes the time to tell Shoto his plan places too much burden on himself. He says was nice of Shoto to be considerate of the girl, but they should have talked it over more first.

Traveling along the telephone cables, Eraserhead uses his restraining bonds to move quickly through the replica city. He catches up to Momo before long and tries to restrain her, but he is unable to keep her Quirk erased and so she escapes. Despite getting free, she runs back towards Shoto rather than towards the escape gate. Shota knows Momo lost her confidence after the Sports Festival and by comparing herself to Shoto, she deems him the better student and doubts her own instincts and abilities. He would like to help her get her confidence back, but "that is not [his] job at the moment," and continues chasing her.

Momo reaches Shoto, but Eraserhead is not far behind her. Shoto takes his teachers advise and encourages Momo to form a plan. When Shota reaches them, Momo stuns him with a flurry of flash grenades. She frees Shoto and tells him that she has a plan to pass the exam. Excited to see his students redemption, Shota wipes his eyes and smirks at his opponents.

Due to his injuries from fighting Nomu, Shota cannot use his Quirk for as long and has to rest more between erasures. He commends Momo for noticing that and planning her attack accordingly. They both run away to put distance between them and Shota. They're not fast enough to escape him, but Shota's unable to keep their Quirks erased and Shoto blocks visibility completely by using his biggest move: Giant Ice Wall. Shota's impressed that they took advantage of his weakness and waited for the right moment. While his students strategize behind the ice, Shota remains in place to watch their approach because the escape gate is behind him. He recalls Momo telling Shoto about her plan to win and admits he is excited to see it.

Momo and Shoto run from behind the ice covered in cloaks. Shota cannot erase their Quirks if they are disguised but attacks anyway because it is a disadvantage for them as well. He restrains them with his scarf, but upper bodies turn out to be just mannequins. Momo uses a hidden catapult to send bundled up restraining bonds at Eraserhead, then Shoto shoots out his flames to heat them up. Momo tells Shota the bonds are made from nitinol alloy: a is a metal with shape memory. When heated it returns to its bundled shape in an instant and ties up Eraserhead.

After the battle, Momo and Shoto discuss how smoothly her plan went. Momo admits she missed the catapult trigger and Eraserhead could have stopped them. She claims that perhaps he allowed them to win. Shota explains that while Momo was revealed, he backed off because Shoto was still cloaked and could have frozen him. Shota is handcuffed by his students and Team Todoroki & Yaoyorozu pass their final exam.

The following day, Shota announces to his class that some did not pass their practical exam. Despite those who failed, Shota reveals that everyone is still going to training camp in the woods. No one managed to fail the written exam, but two teams and Hanta all failed the practical. The teachers left a window for the students to win during the practical battles and only told the students they were trying to defeat them to put them on edge. The training camp is meant to build student strength, so those who bombed the practical need that training the most.

Shota admits they were never going to be separated from the others and that was just another logical ruse. Tenya is upset that Shota has lied to them again and asks if he fears his students losing faith in him. He replies that he was not lying about everything. Those who did not pass will undergo extra lessons that are far tougher then what they would face in summer school.

Forest Training Camp Arc
Prior to summer break, Shota and Vlad King discuss the upcoming train regiment for their students and review each of their quirks. They're interrupted by Denki, Minoru, and Izuku who ask permission to use the school pool. Shota confirms that U.A. grants them permission and dismisses them. When their allotted pool time ends, Shota kicks all of Class 1-A out of the pool and tells them to go home.

Summer break begins and Shota meets with Class 1-A outside U.A. Highschool. He informs them that unlike other students, they will not rest during the break and they will train hard instead. Shota and his students board their bus and head to the training camp in the woods. While on the way, Shoto tries to inform the students that they will stop in an hour but they're all fooling around and not paying him any mind. Shot allows their behavior to slide because he knows this will be their only time to mess around.

The bus stops an hour later at the top of a mountain. Shota announces theirs no point in stopping the bus without reason and introduces the students to the Wild, Wild Pussycats members Mandalay and Pixie-Bob. Once the students realize they have to travel to the base of the mountain on their own, Shota informs them that training camp has already begun. Pixie-Bob tosses the students into Beast's Forest and Mandalay challenges them to reach camp in three hours time. Mandalay questions Shota's intended training schedule for the students because of its intensity. Shota explains that he's trying to get an entire terms worth of training into the students so they can gain provisional hero licenses and defend themselves against villains.

The students don't make it back to camp for several more hours. Shota instructs them to bathe and eat before going to sleep. The next day, Shota makes an example out of Katsuki by having him toss another ball using his quirk. Katsuki only manages to throw it four meters farther than he did during the fitness tests. Shota explains that although the students have grown on mental and technical levels their quirks have not improved at all. The training camp will emphasize expanding the student's quirks. Shota says it will be so hard the students will feel like their dying and he encourages them to stay alive.

Class 1-B arrives sometime later and Vlad King introduces them to the quirk training. Itsuka Kendo questions how Vlad and Shota could look over all the students of both classes. Shota explains the Pussycats have a variety of quirks and experience that will handle all the students at once. Shota brings Eijiro, Rikido, Hanta, Denki, and Mina to a separate facility for extra lessons until two in the morning. At seven in the morning, he brings them to join their classmates for more quirk training. During that day's training, Izuku asks if All Might and the other teachers will join them. Shota confirms that no one else is coming because the camp is a secret. Shota escorts the extra lessons group back to the facility while everyone else undergoes the Pussycat's test of courage.

While Shota and Vlad King discuss the extra lessons curriculum, Mandalay sends out a telepathic message about an attack on the training camp. Shota rushes out of the building worried about the costs of a full scale attack. Distracted, Shota doesn't notice Dabi standing outside and is suddenly ambushed by a blast of blue flames.

Shota narrowly evades the attack and uses his scarf to hang from the building's roof. He erases Dabi's quirk and uses the capturing weapon to pin him down. Shota breaks Dabi's arms while interrogating him to find out the villain's numbers and motives. Some of the students arrive at the facility and distract Shota, allowing Dabi to break free. Shota tries to restrain him again, but Dabi turns out to be a clone. As the clone disintegrates into a puddle, Dabi threatens the safety of the students.

Shota rushes into the forest and happens upon Izuku. Izuku is heavily injured from combat with one of the villains. Izuku asks Shota to look after Kota because he needs to give Mandalay a message immediately. Before Izuku rushes off, Shota warns him about going beyond his physical limits. He also gives Izuku a message for Mandalay. Thanks to Dabi's message, Shota knows that the students are the targets of the attack. He grants the students permission to engage the villains and defend themselves using their training. He worries about Izuku and his students, pleading for them not to let their journies on this night. Kota tearfully asks Shota if Izuku will be okay despite his injuries. Shota tells the young boy that Izuku will be okay, and to focus on thanking him for the next time they meet.

Shota and Kota reach the facility. Shota defeats a second double of Dabi and entrusts Kouta's safety to Sekijiro Kan. The Class 1-A students want to fight, but Shota prevents them from doing so since they do not have enough information on the villains. Shota heads towards the front lines. Along the way, he helps rescue a few Class 1-B students. The attack of the Vanguard Action Squad ends and the training camp comes to an abrupt ending.

One day later, Shota and Sekijiro are questioned by the Police Force regarding the events that transpired at the training camp.

Hideout Raid Arc
Nezu, Shota, and Sekijiro appear in U.A.'s public apology broadcast. However, the apology and their safety measures are still criticized by society. Shota tells the reporters that he decided to let the students fight due to not knowing the full situation in order to prevent the worst possible situation from happening and as a result no students were killed (which would have been the worst possible outcome in his opinion); Nezu states that the situation would have been much worse if Tetsutetsu Tetsutetsu and Itsuka Kendo did not defeat Mustard. Nezu also says that they are seeing to the well-being of their students and have not seen any signs of emotional trauma. The reporter asks the principal if U.A. had already failed in securing the students' well-beings due to not checking Katsuki's mental instability and his "villain-like" performance during the Sports Festival. Remaining calm even under pressure, Shota answers that out of all the students, Katsuki was the one who showed that his conviction to be a Hero was the strongest and believes the villains' to be foolish if they think that they can turn Katsuki into a villain. Nezu backs up Shota by saying that they are working with the Police Force to investigate Katsuki's whereabouts and promises to retrieve him.

After the broadcast, Shota, Nezu, and Sekijiro watch All Might fight against All For One. After All Might's victory and return to U.A., Nezu announces his plan to transition U.A. to a boarding school as a means to mitigate the safety issues, and asks for Shota's cooperation.

Shota and Toshinori visit the homes of Class 1-A. During the visit to Kyoka's home, 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.

During the visit to Katsuki's home, Mitsuki Bakugo is more than happy to allow her son to relocate to U.A.'s dormitories. She is confident in U.A. because Shota sees her son for who he is instead of what he can do. She 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. After leaving the Bakugo household, Shota decides to visit the other Class 1-A families by himself while Toshinori goes to visit Izuku.

Provisional Hero License Exam Arc
Ten days before the beginning of the second semester, Shota is glad that everyone arrived safely. He tells Class 1-A that at the training camp they were supposed to get their "Provincial Hero Licenses" but due to the League of Villains' attack, they did not. Shota is disappointed that some of them tried to act like they have their licenses; Shota calls out Shoto, Eijiro, Izuku, Momo, and Tenya. Shota tells them that he knows that they were present at the site of Katsuki's rescue and took it upon themselves to rescue him. The rest of Class 1-A are shocked and surprised that they actually went to rescue Katsuki. He also knows that the rest of Class 1-A except Katsuki, Toru, and Kyoka also knew about their plan to rescue Katsuki. He explains that their actions have been covered up but tells them that if All Might did not retire, he would have expelled them all as punishment, with the exception of Katsuki, Toru, and Kyoka. Shota advises them to go through the proper procedures next time, which will also restore the trust between them.

After Class 1-A's mood has become better as a result of Katsuki's actions, Shota shows them their new dormitory; Heights Alliance has one dorm per class and Shota takes them to the Class 1-A dormitory. Shota explains that their dorm is separated by gender: the right wing for females and left wing for males. However, the first floor is common space and contains the dining area, baths, and laundry facilities. Class 1-A take a look at their new dorm and become excited about living here. Shota then explains that their bedrooms are on floors two, three, four and five; every student gets their own private bedroom with each room having an AC unit, bathroom, refrigerator and closet. Shota gives Class 1-A a map of their room allocations and says that their luggage has already been sent into their allocated rooms. Shota ends his explanation by telling Class 1-A to spend the rest of the day unpacking and organizing their rooms. Tomorrow, he will explain the operations of their new lifestyle.

Internship Arc
Shota introduces the big three to his students and announces the internships.

Shota scolds at Izuku and Katsuki for having a fight on school grounds. Before All Might steps in and tells him the reason for the fight, though he understands Shota still punishes the boys by giving Izuku three days of punishment since he defended himself while Katsuki is given a longer time for initiating the fight. He sends them off to Recovery Girl while berating them for their reckless act.

Shota is one of the heroes involved in rescuing Eri.

The villains were interested in Shota’s quirk but couldn't defeat him. When Izuku's quirk starts to act out of control, Shota uses his quirk on Eri to deactivate her quirk and save Izuku.

Sometime later, Shota spoke with Mirio and told him of a possibility of Eri getting control of her Quirk in the future, which will allow her to be able to restore him to a state where he had his Quirk.

U.A. Cultural Festival Arc
In Class 1-A, Shota announces that U.A will be having a culture festival and explains that the culture festival is sponsored by the other departments such as the General Department. However, Shota points out that part of the festival will be within U.A and tells Class 1-A to pick out a program to perform at the culture festival. Tenya asks ideas from Class 1-A; many of them give creative ideas such as Denki's maid cafe or Ochaco's mochi shop. Soon, Class 1-A reaches many ideas. Before class ends, Shota tells Class 1-A to make a decision by tomorrow otherwise the class will be doing a public lecture.

Shota Aizawa tells Izuku that Eri has requested to see him and Mirio.

Izuku asks Shota if Eri can come to the culture festival. Mirio explains to Eri that the culture festival is an occasion that U.A. High School hosts where there will be lots of events on display where people can enjoy themselves while tasting delicious food such as candied apples, which catches Eri's attention. As Shota phones Nezu to get his approval, Izuku asks Eri about his idea; Eri wants to get to know the people who saved her and agrees to go to the culture festival.

At U.A. High School, Sekijiro Kan comments to Shota Aizawa on his Class 1-A's band and dance performance, considering it to be admirable.

Joint Training Arc
As Izuku and Toshinori are walking down the hallway, they run into Shota and Shinso walking out of a room. He comments on Izuku’s and Toshinori’s close relationship, and tells Toshinori to calm down when he acts flustered. He then tells Izuku to suit up, as they have a busy day ahead. When he arrives at Ground Gamma, he uses his Capturing Weapon to choke Monoma in the middle of a rant, and announces that Shinso is trying to join the hero department, and will be joining their exercise.

Shota asks Shinso to introduce himself to the other students, and helps Vlad King explain the rules of the joint training exercise. Shota watches silently during Shinso’s first battle of the exercise.

After the first battle ends, Shota asks his students to state what they’ve learned during the exercise. When Shinso expresses his frustration about his difficulties with the Capturing Weapon, Shota reassures Shinso by pointing out that it took him 6 years to master the weapon, and tells him to use his feelings as motivation in the next battle. He then advises the rest of the team about how to improve for the future. As Toshinori and Midnight contemplate their students’ growth, Shota and Vlad join them and asks for their opinion on Shinso, and Shota explains that the exercise is Shinso’s “exam” to determine whether or not he will join the hero program.

During the second battle, Shota watches silently as Momo declares her confidence.After Class 1-B’s victory, Shinso notes the destruction caused by the battle, and Shota replies that this normal, but scolds Manga and Itsuka for causing too much damage.

When Kaminari and several other Class 1-A students protest Vlad’s biased commentary during the start of the fourth battle, Shota tells them to stop, reminding them that their losses would be serious in the real world, and that the Class 1-B students have had better tactics.After Class 1-A’s victory in the fourth battle, Shota complimented his students on their teamwork, then rejoined Toshinori, Midnight, and Vlad to watch the final battle.

As the final battle of the exercise progresses, Shota watches with shock as a strange black substance appears from Izuku’s arm.Once the crisis is averted, Shota asks that the battle be allowed to continue, despite Vlad’s protests, as the students still want to fight. While watching the fight between Izuku and Shinso, Shota remembers his time training Shinso to use the Capturing Weapon.Shota expresses confusion when Izuku uses Blackwhip properly for the first time, and comments when it disappears.

After the end of the battle, Shinso once again laments his performance, and asks if this was his “exam”, to which Shota avoids the question and announces the assessments. He asks Izuku about his outburst during the battle, and compliments Uraraka’s growth. When Shinso continues to berate himself, Shota briefly chokes him with his weapon and reminds him that the other students went through a lot of training to achieve their skills, telling him to focus on improving himself. Shota announces that Shinso has passed his test. He then asks Monoma to visit Eri the next day.

The next day, Shota presented his case for Shinso’s transfer to the other faculty, and earned Nezu’s approval. As he was walking down the hall, Present Mic notes the similarities between Shota and Shinso, and asks if he’s taking another pupil, to which Shota asks him to keep it short, as he has somewhere to be. Shota meets Eri, Monoma, Izuku, and Mirio outside of the teacher dorms, and explains why he asked for Monoma’s help.
