Toshinori Yagi ( Yagi Toshinori), also known as All-Might (オールマイト Ōru Maito), is the No. 1 Pro Hero who bears the title of the world's Symbol of Peace (平和の象徴 Heiwa no Shōchō). He teaches Foundational Hero Studies at U.A. High School.
All-Might was the eighth holder of the One For All Quirk after receiving it from Nana Shimura. He has since passed the torch onto Izuku Midoriya, whom he is training to be his successor. After using up all the embers of One For All to defeat All For One, All-Might retired and ended his era as the world's greatest hero.
== History ==
=== The Origin of All-Might (1980-1993) ===
Toshinori Yagi was born Quirkless during a time in the world where evil and chaos ran rampant due to the influence of All For One. Crime rates were on the rise because citizens had no hero to believe in. With all his family having been killed, and seeing so much destruction in the world, inspired the boy to become a powerful hero who could provide hope for innocents and defeat evil.
During his teenage years, Toshinori would often rush into danger to try and lend a helping hand, even despite his powerlessness. One day, he was prepared to face off against a gang of Villains with nothing but a lead pipe, only to see them all being swiftly dispatched by the Pro Hero, Nana Shimura. Floating above the defeated adversaries, she noticed the young Toshinori looking at her with admiration, asking what he was going to do as he attempted to fight them with just a lead pipe.
Fascinated and astonished of Nana, he asks her to please take him on as her pupil, but she coldly refuses telling him he doesn't even have a Quirk. She tells him to stop following her and to take his pipe elsewhere, and Toshinori responds that his family was killed a while ago, with Nana simply responding so was her's and she doesn't have time to help seek revenge. Toshinori says that he just can't accept a world where those who take from others come out on top, the grief of those who have been stolen from turns to hatred in an endless spiraling cycle.
Asking for his solution, Nana turns around and is surprised as Toshinori explains his ideals saying 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. He points toward the destruction nearby noting that even with new buildings and restoration efforts, people have been living in fear for a while, with their hearts and minds shrouded in darkness. Nana asks if he would put on a grand display of power, and he responds that everyone has it tough with their own problems so he would step up, because a Quirkless guy like him has no role otherwise.
In spite of his Quirkless-ness, Nana believed in his ideals and decides to take him as her apprentice. Shortly before high school, she passed her other Quirk, One For All, down to him, making him the eighth torchbearer of the great power. Toshinori would go 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 alongside Nana. 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 instilled an innate fear within him.
=== All-Might Rising (1994-1998) ===
Throughout Toshinori's high school years, Nana and Gran Torino train Toshinori to harness the full power of One For All. During Toshinori's final year, the three of them faced off against All For One in a deadly battle. Despite the three of them working together, the villain was too powerful, resulting in Nana being wounded, with Toshinori and Gran Torino defeated shortly afterwards.
Realizing they wouldn't be able to win, Nana decides to do what is necessary and forcibly pushed Toshinori out of the way. He calls out to his master as Gran Torino swoops in and flies him away. Nana says she's leaving the rest to Toshinori and asks her friend to make sure his dreams come true. With her back turned, Nana points to Toshinori, signaling his time has come to take her place. Nana turns to her successor and with one last smile, reminds him that she's counting on him to save the world.
Toshinori tearfully screams for his master as Gran Torino flies away filled with grief. Knowing in her heart that Toshinori will rise up to take her place, Nana turns to face her nemesis. The evil mastermind thanks her for entertaining him and finishes her off with a powerful explosion created from a surge of black lightning, which destroys the entire island.
As a promise to his close friend Nana, Gran Torino continued training Toshinori in her place. However, Toshinori was demoralized and distraught after the death of his master, and was unable to train properly to his potential. Thoughts of revenge plagued Toshinori's mind and he wished to avenge Nana, who he saw as a true hero. During one of his training sessions at U.A, Gran Torino reminds Toshinori that no matter what city he hides in, All For One's reach will find him as he has influence everywhere. Toshinori replies that he needs to try and fight back so he can become the Symbol of Peace and passionately throws a counter punch.
Gran Torino kicks Toshinori hard on the ground and sits on top of him while enjoying his favorite taiyaki treats. He reminds Toshinori that his enemy is a man with monstrous abilities who's walked the earth for more than over a hundred years, expressing that he could never defeat All For One in his condition. Frustrated, Toshinori cries 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 lifts his sobbing student and tells him he needs to cross the ocean after he graduates. He fears that if Toshinori doesn't escape the villain's reach, then Nana's sacrifice will be for nothing. Grieving, Gran Torino asks Toshinori if he understands why Nana let him escape. He asks Toshinori to save his power and train in the United States so All For One could not reach him and to gain experience as a hero. This conversation restored Toshinori's resolve with a new purpose.
That spring, Toshinori graduated from U.A. and prepared to head to America. 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 (1999-2005) ===
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. It was also during this incident that All-Might saved a young Cathleen Bate, which inspired her to become a hero just like him, and eventually would become America's Number 1 Hero, Star and Stripe.
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.
=== The Ways of The Hero (2004) ===
While in America, David recommended Toshinori meet America's top hero--who is only five years younger than Toshi--The Immortal. The two of them would go on missions together and teach each other things that the other had not known. Over this short time that they worked together, they developed a close working relationship, and even earned a name for the two of them as a duo.
Their biggest exploit during this time was when the supervillain known as Nightshade was launching an assault on a police station, attempting to raid it and murder every single officer in that station. Immortal informed Toshinori of Nightshade's powers, as well as his own personal history with Nightshade, and the fact that this is his arch enemy.
A fight ensued the moment the heroes arrived on scene, and Nightshade surprisingly put up a good fight against The Immortal, but the moment he tried to take on Toshinori, he nearly got killed. America had never seen a hero this strong, and Nightshade was taken aback by this level of power. After a few solid blows, Nightshade was out for the count and Toshinori aided The Immortal in restraining the villain-of-the-week until the police had arrived, so as to put quirk-dampening handcuffs on him and take him away.
Toshinori and The Immortal fled and traveled around with The Immortal giving him some tours of locales and the occasional crime stopping activity.
=== Return to Japan (mid 2000s-early 2010s) ===
Eventually, Toshinori returned to Japan and his meteoric rise would only continue through the Bronze, Silver, and Golden ages of his career, soon 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, ushering 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, with Toshinori even revealing the truth about One For All to him.
=== The Underground Masquerade (2016) ===
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 Overclock Quirk 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 (2030) ===
Eventually, destiny caught up with him, and once again, All-Might was brought face to face with All For One in a single brutal combat. The Symbol of Peace became the first torchbearer to defeat All For One, completely obliterating his head, and severely damaging the rest of his body. All For One's reign over Japan was finally over, and All-Might took steps to ensure that their battle wouldn't reach public eyes or records, being kept a secret from most people in the world. However, this victory was at the cost of critical injuries dealt to him, as All-Might's stomach was lost, and his respiratory system was damaged beyond repair. This created a time 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 confessed that he even used his Foresight Quirk on him when he was still on the mend, and warned 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.
=== Vigilantes Beginnings Arc (2031-2032) ===
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 Airjet, 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 (2032-2033) ===
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 Toshinori. Upon hearing Naomasa's call, Toshinori 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, Toshinori 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. Then he notices Captain Celebrity and Koichi are still falling. He immediately rescues both. All-Might congratulates Captain Celebrity for what he has done and signs Koichi's hoodie.
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 Toshinori Yagi, 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 Toshinori tells him that it's fine and that it was his impassioned plea that got him there in time. Toshinori 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 Toshinori 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 (2034) ===
One year has passed since the Sky Egg Bombing, and since then the mastermind behind it, Number 6, has cooked up a revenge plan against Koichi and a hospitalized 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 his Anonymous ordered 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 himself.
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.
With the threat of Number 6 and the Villain Factory seemingly over, Toshinori returns to his daily routine at the Might Tower. Sometime later, in order to raise a proper successor, All-Might enlisted himself as a teacher at U.A. High. 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.
=== Weight of the Symbol (2035) ===
One night while Toshinori was cleaning up before shutting down Might Tower until the morning, he is stopped in his tracks before exiting his office when he senses someone else in the room with him. He stops in front of the doors and stands in silence, before--in one swift motion--turning around and flying into the shadows, grabbing onto the neck of a man in a black and gray villain costume. The man greets Toshinori and asks if he remembers who he is. Toshinori claims that he has made a lot of enemies, so this man will have to be more specific. The man tells him,
Suddenly, Toshinori remembers. During his early days when he was touring America, he made quick work of The Immortal's arch enemy who went by the name "Nightshade". Apparently, this villain went on to be the single most notorious villain in America's history, for killing over fifty heroes (including ten Pro Heroes) in the span of just under a decade. Toshinori tells Nightshade he now remembers, and calls Nightshade a monster for all the crimes he has committed and good people he has murdered. Not being known as someone to smile Nightshade smiles slightly before quickly placing a small metal device on Toshinori's chest. At first, Toshinori laughs it off, until everything disappears.
He wakes up in a house overlooking Tokyo. The sun is shining brightly, the birds are chirping, and the world is at peace. He yawns and stretches his arms out to the sides, looking over at his wife next to him. He gets out of bed and meanders his way to the kitchen, where he puts a pot of coffee on and turns on the news, where he sees news about the crime rates globally dropping to only 3.2% thanks to the world's top hero: Kagayaku Hikari (輝く光 Radiant Light). It is now 2040 and Toshinori has been retired from the All-Might moniker for years now, having taught at U.A. and found his successor to pass One For All onto; that being Kagayaku Hikari.
Shortly thereafter Toshinori's wife, Ichika, wakes up and makes her way to the kitchen, pouring herself and Toshinori cups of coffee, before sitting down on the couch next to him. As Toshinori watches the news recount the triumphs of his successor, he can't help but grin with pride and happiness. Ichika looks over at him and congratulates him for his achievement both as a hero and as a man for training Kagayaku Hikari right.
About half an hour goes by, and Toshinori gets up to start getting dressed in his All-Might suit to head to U.A. for the commencement ceremony, as principal Nezu had called him to come and speak to the graduates, as well as to officially declare Kagayaku Hikari to be his successor. He arrives just as the ceremony begins, and transforms into his hero form to step out onto the podium and deliver a powerful speech about heroism and perseverance through difficult times. As he introduces Kagayaku Hikari, a group of villains appear and start attacking the staff of the school, as well as the students. A fight ensues, which results in Kagayaku Hikari being fatally injured, and Toshinori having to avenge him and become the top hero again. He closes his eyes in grief of his protégé.
Upon reopening his eyes, he is back in his office in Might Tower, as the world's number two hero, Endeavor and the new hero; Kamui Woods are in his face. Endeavor is finishing ripping the device off of Toshinori's chest that Nightshade had placed on him, and Kamui Woods is fighting Nightshade. Enraged, Toshinori leaps at Nightshade and starts fighting him, demanding to know what was done to him. Nightshade simply responds,
Toshinori, unsure of how to feel about what he saw, refuses to answer the question, and continues to beat down on Nightshade, brutalizing him while using only 0.01% of his full power. After a few minutes of Nightshade desperately trying--and failing--to fight back against Toshinori, Toshinori finally incapacitates him. Rather than subjecting him to the same fate that Nightshade attempted to subject Toshinori to, the Pro Heroes decide to turn him into the authorities, where he is sentenced to life in prison for each hero he has killed (55 life sentences) and he is to serve the first ten years of his prison time in Tartarus, before he will be deported back to America and forced to spend the remainder of his sentence in Supervillain Correctional Facilities.
After having some time to reflect on the events that took place that night, Toshinori calls Nezu, the Principal of U.A. High School and tells him that he is one hundred percent certain that he wants to take that teaching job at the school. Nezu agrees, and now Toshinori has the perfect place to find out if his vision was a premonition or just something his heart desired.
=== Teaching at U.A. High School (2036) ===
==== Entrance Exam Arc ====
Toshinori 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. Toshinori uses his Texas Smash to blast the villain apart and saves Izuku. While the young man recovers, Toshinori encases the villain inside a couple of empty bottles, in order to take him to the authorities. When Izuku awakens, he finds that Toshinori has signed his Hero Analysis for the Future notebook and thanks him profusely.
Toshinori prepares to leave, but the young fanboy holds on to Toshinori after he leaps high into the air. At first, Toshinori 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, Toshinori's time in his muscle form comes to an end and he reverts to his true form, shocking Izuku.

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, Toshinori's time in his muscle form comes to an end and he reverts to his true form, shocking Izuku.
Toshinori 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.
Toshinori 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, Toshinori 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 Toshinori is inspired enough to step in and use Detroit Smash to defeat the villain, saving both Izuku and Katsuki. Toshinori is swarmed by reporters after the battle.
Later on that same day, Toshinori appears before Izuku, thanking him and giving him a proposal. Toshinori 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.
Toshinori 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 Toshinori 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 Toshinori'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 of a Quirkless middle schooler becoming his successor. Toshinori and Nighteye argue over the phone regarding Izuku; Toshinori argues that Izuku was intent on saving others while Nighteye argues that intentions alone were not good enough since there are far more capable candidates with the same good will as Izuku. However, Toshinori states that being Quirkless is what made Izuku a befitting candidate over the others. This argument would result in Toshinori and Sir Nighteye falling out and no longer being on speaking terms as a result.
Toshinori 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 Toshinori by cleaning the whole beach and becomes a genuine vessel. Amazed by his feat, Toshinori rewards Izuku for his hard work by having Izuku consume a piece of his hair, enough DNA to transfer One For All to Izuku.
Toshinori 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, Toshinori 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 ====
Toshinori 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. Toshinori approaches Shota, calling him a liar and says that he saw that he once expelled an entire new class of first-graders last year. Toshinori 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. Toshinori then says that they will never get along. Toshinori 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 ====
Toshinori (showing up to class in his Silver Age costume) 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.
Toshinori then decides that the teammates and pairs will be chosen by lottery. After the lottery, Toshinori 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. Toshinori 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, Toshinori 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. Toshinori 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.
Toshinori 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, Toshinori is about to suspend it, but after hearing Izuku call out to Ochaco, he stops. After Ochaco touches the core, Toshinori announces that the Hero team wins.
Toshinori 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, Toshinori 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, Toshinori 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 Toshinori 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. Toshinori 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 Toshinori decides to leave Katsuki alone, finding that teaching can be difficult.
==== U.S.J. Arc ====
While heading to U.A., Toshinori sees Kamui Woods and Mt. Lady fighting the villain Habit Headgear, who had a family as hostages. Toshinori 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 Toshinori telling him that he revealed to Katsuki about the secret of the One For All Quirk. However, Toshinori 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, Toshinori 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. Toshinori 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. Toshinori quickly dispatches the villains in front of Shota, apologizes to him and picks him up. He then rescues Izuku, Minoru Mineta, and Tsuyu Asui. Toshinori asks the three to head to the entrance and leaves Shota with them. When Izuku tries to dissuade him into fighting, Toshinori tells him it is all right. Toshinori prepares to face the main people in charge of the attack: Tomura Shigaraki, Kurogiri, and Nomu.
Toshinori 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, Toshinori uses a backdrop slam against Nomu, causing an explosion. However, Kurogiri opens a gate with his Quirk, causing Toshinori's attack to fail and allows Nomu to grab Toshinori. However, the combined efforts of Katsuki and Shoto allow him to escape from Nomu.
Toshinori then blocks a punch from the regenerated Nomu, giving Katsuki some time to evade. Toshinori 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, Toshinori decides to go all out. He and Nomu get into a fistfight and Toshinori sees that he can absorb each punch at 100%.
Toshinori 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, Toshinori 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, Toshinori prepares to fight Tomura.
Toshinori asks why he is not going to fight since it is his mission to kill him. Toshinori 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 Toshinori, but Izuku intervenes to protect the powerless Toshinori. However, one of the heroes that Tenya called as backup stops Kurogiri and Tomura from attacking him.
Toshinori 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 Toshinori's weak form. Cementoss tells Toshinori 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, Toshinori 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.

When Izuku says he could not do anything, Toshinori 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.
Toshinori and Izuku are taken to the U.A. Nursery to being treated by Recovery Girl. Soon detective Naomasa arrives to inform him and Izuku freaks out that he sees Toshinori in his true form, but Toshinori calms him down by telling him that Naomasa is one of the few who knows his secret and that he fully trusts him. Then Toshinori asks the detective 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 Toshinori worries. Toshinori tells Naomasa that the students fought bravely and that they will become great heroes, to which the detective agrees.
==== U.A. Sports Festival ====
Toshinori 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, Toshinori 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, Toshinori finds Izuku and asks him to have lunch with him. In the resting room, Toshinori 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 Toshinori.
He then tells Izuku that his time as the Symbol of Peace is heading to an end, much to Izuku's sadness. Toshinori 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 "Toshinori" and the future Symbol of Peace, shocking Izuku. Toshinori states that he wants Izuku to demonstrate his full potential to everyone at the Sports Festival.
After Izuku doubts himself, Toshinori 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. Toshinori 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, Toshinori smiles and claps for him. Toshinori 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, Toshinori 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, Toshinori in his hero form greets Enji, saying it's been a while and asks him to have tea with him. Toshinori 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, Toshinori stops him, saying that his son Shoto was able to show a great performance even without using half of his power. Toshinori then asks Enji for advice on how to raise the next generation. Enji comments on Toshinori's attitude, finding it to be annoying and then says that he will make Shoto a hero that surpasses Toshinori, then angrily walks away.
Toshinori 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, Toshinori 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, Toshinori cheered him up; telling him to do his best and encourages him to smile when he is full of fear and anxiety. Toshinori then concludes that he is always watching Izuku.
Toshinori decides to watch the fight between Izuku and Hitoshi from the arena entrance. He begins to freak out when Izuku falls under the influence of Hitoshi's Brainwashing Quirk and begins to walk out of bounds. Toshinori is uttering for Izuku to stop, but to no avail. Izuku manages to break out of the trance since something strange happened with the One For All. After this, he defeats Hitoshi and moves on to the next round.
Toshinori goes to the infirmary to see Izuku. After Chiyo scolds Toshinori for putting pressure onto Izuku, Izuku tells Toshinori about the mysterious shadows he saw, saying that the shadows helped him break free of Hitoshi Shinso's Brainwashing and asks Toshinori if what he saw were the people who wove the power of One For All.
Toshinori replies that he too saw something similar to what Izuku saw in his younger days. Toshinori 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 willpower from seeing the vision helped him break Hitoshi's brainwashing. Izuku is not completely satisfied with the explanation, but Toshinori 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 Toshinori replies that it is a good thing.
The tournament continues until it is Izuku's turn again. During the match between Izuku and Shoto, Toshinori 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, Toshinori remembers Endeavor's words of making his son surpass him. Soon after remembering, Toshinori 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, Toshinori concludes that Izuku is trying to save Shoto from his cruel fate, despite wanting to win. Toshinori 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, Toshinori goes to Recovery Girl's Nurse's Office to see Izuku. She scolds Toshinori for making Izuku push his limits and tells Toshinori not to try and praise Izuku for going so far. When Izuku apologizes to Toshinori for not living up to his expectations, Toshinori's face is filled with regret. After Izuku tells Toshinori that all he wanted to do was help Shoto and asking for forgiveness, Toshinori 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 Toshinori to try and find a different method for Izuku to use his One For All. Izuku leaves Chiyo's room with Toshinori and they walk down the corridor. Izuku sadly tells Toshinori that he thinks someone else should be his successor. However, Toshinori tells Izuku that he used to be Quirkless just like him, which surprises Izuku. Izuku says to Toshinori that he never knew about that information causing Toshinori to reply that Izuku never asked him.
Toshinori 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 Toshinori. Toshinori tells him to watch the rest of the U.A. Sports Festival, to which he complies.
Toshinori, 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 Toshinori makes his way into the stadium, Midnight unintentionally talks over him, ruining Toshinori's entrance. Toshinori 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.
Toshinori 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 Toshinori that he must come to terms with things to solve his problems, Toshinori 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.
Toshinori then goes to give Katsuki his medal for first place, finding the restraints to be a little too much. Toshinori takes Katsuki's face mask off, causing Katsuki to angrily yell that he does not deserve to be Number One. However, Toshinori tells Katsuki that society will acknowledge him as Number One even if he does not. Toshinori gives Katsuki his medal.
Afterwards, Toshinori 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. Toshinori 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.
==== Hero Killer Arc ====
Toshinori is in U.A.'s Faculty room. Ken Ishiyama informs Toshinori that a new nomination has just arrived for the freshmen, telling Toshinori that the nomination is for Izuku. Excited, Toshinori goes to check who nominated Izuku. As he checks, Toshinori becomes flabbergasted at the person who nominated Izuku.
After school that day, Toshinori appears in front of Izuku as he is about to leave class. Toshinori and Izuku walk along the corridor. Toshinori says that Izuku received a nomination, much to Izuku's surprise. Toshinori tells Izuku that the person who nominated him was Gran Torino. Toshinori explains that Gran Torino was a Pro Hero who taught at U.A. for one year and that Gran Torino was his homeroom teacher. Toshinori says that Gran Torino was a close friend of his predecessor, but now he is in retirement. Toshinori says that Gran Torino knows about the One For All Quirk which is the reason why he must have nominated Izuku.
Shaking nervously, Toshinori 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, Toshinori 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, Toshinori informs Izuku that his hero costume has been repaired.
Naomasa meets with Toshinori at U.A. He tells Toshinori 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 Toshinori 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. Toshinori becomes concerned as he fears that All For One has returned.
After Stain's defeat is published, Gran Torino speaks to Toshinori 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 Toshinori that Izuku has improved drastically in using One For All, saying that Izuku movements are similar to his own; Toshinori 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, Toshinori's predecessor.
Toshinori thanks Gran Torino for everything as he wouldn't be the man he is today without him; Gran Torino brings up that Toshinori never visits him, to which Toshinori 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 Toshinori'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 Toshinori's predecessor and gave Toshinori his scars, All For One has returned. Toshinori is in disbelief that All For One had survived, not wanting to believe it given the serious injuries Toshinori inflicted on him. Gran Torino advises Toshinori 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 Toshinori. Toshinori 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 Toshinori. 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. Toshinori watches the race and is surprised and amazed at Izuku's new control of his Quirk and his movements, although he stumbles and ends up last, with Hanta winning the race.
Toshinori commends the group on improving their Quirks more broadly since entering U.A. He asks them to prepare for the end-of-term test. Toshinori then approaches Izuku, telling him that he is impressed with his improvement and gives him a subtle thumbs up. Toshinori 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.
Toshinori meets with Izuku in the Break Room. Toshinori 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. Toshinori 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, Toshinori 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. Toshinori tells Izuku that One For All is a special Quirk and begins telling Izuku One For All's origin. Toshinori says that One For All is derived from a Quirk that has existed since the beginning.
Toshinori 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. He 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 Toshinori to reply that underground dealings are never recorded in the textbooks.
Izuku asks how this man is related to One For All. Toshinori says that All For One can grant Quirks, but those who were not able to handle the strain became brain-dead like Nomu. Toshinori explains that there were cases for those who did survive the procedure where their Quirks mutated. Toshinori 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.
Toshinori 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. Toshinori theorizes that the man stole a Quirk that stopped his aging or a Quirk that granted him immortality. Toshinori 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; Toshinori says that he was finally the successor that defeated the older brother, or so he thought. Toshinori tells Izuku that the man possessing All For One has returned and is leading the League of Villains. Toshinori 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.
Toshinori apologizes for giving Izuku so much information. Izuku says that whatever task Toshinori gives him he will accomplish no matter what as long as Toshinori is by his side. Toshinori 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 ====
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. Toshinori tells the wonder duo to cooperate together and come at him to win.
Toshinori, Izuku, and Katsuki get onto a bus and drive to an uninhabited city where the test exercise will take place. Toshinori, Izuku, and Katsuki arrive in the city. Toshinori explains the test exercise: Izuku and Katsuki have two options of winning and passing the test exercise; they must either handcuff Toshinori 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. Toshinori 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, Toshinori throws a punch which devastates the area Izuku and Katsuki are in; Toshinori says that he will have to get involved.
Izuku is shocked at the level of Toshinori's (even though he knows that Toshinori is handicapped and severely weakened to begin with). Toshinori declares to the duo that he is a villain and collateral damage means nothing to him. Toshinori 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 Toshinori which distracts him. Katsuki charges at Toshinori, but the Symbol of Peace grabs Katsuki's face, stopping his advance. Katsuki launches a flurry of Explosions against Toshinori. However, Katsuki's Explosions do not even scratch Toshinori. Toshinori slams Katsuki down onto the ground. Toshinori turns his attention to Izuku who planned on running away. Toshinori questions Izuku on his decision to escape. Izuku recalls the Hero Killer and activates 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.
Toshinori appears in the air with a guardrail in his hands; Toshinori slams the guardrail on Izuku which pins him down to the ground. Then, Toshinori punched Katsuki in the stomach, greatly injuring him and sending him flying backward. Toshinori approaches Katsuki and says that he understands his jealousy of Izuku's sudden growth; Toshinori 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 Toshinori that if he must rely on other peoples' strength, then he would rather lose. Disappointed with Katsuki's decision, Toshinori prepares to finish off Katsuki; Katsuki tries to move but to no avail. Suddenly, Izuku activates Full Cowl and breaks free of the guard rail; Izuku charges and punches Katsuki out of harm's way.
Toshinori chases after Izuku and Katsuki. Suddenly, Katsuki appears from behind and attacks Toshinori with an Explosion which distracts Toshinori. However, one of Katsuki's Grenadier Bracers is missing. Suddenly, Izuku appears behind Toshinori with Katsuki's missing Grenade Bracers equipped on him. Katsuki yells at Izuku to commence his attack; Izuku aims the Grenade Bracer at Toshinori and releases the grenade pin.
Izuku releases the grenade pin and blasts an immense Explosion at Toshinori at point blank range. After the Explosion is finished, Izuku and Katsuki dash towards the exit. Toshinori easily takes the Explosion, only coughing up a little blood. Toshinori is impressed with the duo's strategy; Toshinori 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. Toshinori decides to chase after the escaping Izuku and Katsuki, declaring that he will give it his all.
Toshinori catches up to Izuku and Katsuki and defeats them; Toshinori pins Katsuki down on the ground with his foot and dangles Izuku in the air with his arm. Toshinori 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. Toshinori is surprised to learn that his colleague, Shota, has been defeated. Toshinori 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 Full Cowl, but Toshinori stops him and throws him onto the ground. Toshinori decides to finish off Izuku and Katsuki.
Suddenly, Katsuki gets up and launches a big explosion against Toshinori, which distracts the Symbol of Peace. While Toshinori is distracted by the light, Katsuki grabs Izuku and throws Izuku towards the escape gate with an Explosion. To prevent Izuku from escaping, Toshinori uses New Hampshire Smash and blasts himself into Izuku which crushes Izuku due to Toshinori's great weight and sends him tumbling down.
Katsuki chases after Toshinori; Katsuki tells Toshinori 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 Toshinori (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 Toshinori so that Izuku has time to escape; Katsuki uses another huge Explosion against Toshinori. However, although the great Explosions have distracted Toshinori, the Symbol of Peace is still unscathed.
Izuku gets up and prepares to activate Full Cowl so that he can leap towards the escape gate. Not allowing Izuku to make an escape, Toshinori prepares to attack Izuku but Katsuki intercepts Toshinori's attempt. Izuku successfully activates Full Cowl and begins his escape while Toshinori smashes Katsuki into the ground. Izuku sees that Katsuki is in trouble. Despite being greatly injured, Katsuki yells at Izuku to escape and bites Toshinori's hand. Toshinori 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 Toshinori's words; that when times are scary and uncertain, you face it all with a smile. Izuku smiles and punches Toshinori in the face. While Toshinori is suffering from slight recoil, Izuku grabs Katsuki who has fallen unconscious. Izuku rushes towards the escape gate with Katsuki in tow. Toshinori shrugs off Izuku's punch and watches him escape. Toshinori understands by now that Izuku is the type of person to save somebody; Toshinori notes that whenever Izuku tries to save somebody, there's never a wall in his way.
After Izuku and Katsuki pass the practical exam, Toshinori carries them to Recovery Girl's tent to be healed. Recovery Girls scolds Toshinori for not restraining himself during his battle with Izuku and Katsuki. Recovery Girl asks Toshinori to take Izuku and Katsuki back to U.A. to recover. After Izuku requests to stay, Toshinori leaves carrying an unconscious Katsuki in his arms, he notes that Izuku will be extraordinarily strong one day. Toshinori walks out of the tent and prepares to carry Katsuki back to U.A. Toshinori notes that Katsuki himself is also incredible and that whenever there is a wall in front of Katsuki, he laughs at it.
After the exams and the semester are over, Class 1-A heads out on a group trip as friends to the Kiyashi Ward Shopping Mall. Later that day, Toshinori and the other teachers at U.A., as well as many other Pro Heroes, are informed of a situation that occurred at the mall earlier. They are told that Izuku Midoriya had come in contact with Tomura Shigaraki in what seemed to be a chance encounter. Apparently, Shigaraki had threatened Midoriya's life.
Toshinori goes to the Police Station, meeting Izuku and Naomasa outside; and he apologizes to the boy 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 he decides against it. Naomasa concludes their conversation by saying that they will capture All For One this time, to which Toshinori agrees.
==== I Am Here ====
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 about the time he told David that he wanted 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 Toshinori transforms into his muscular form, and double checks everything including if Izuku got permission to bring his hero costume along.
On I-Island, Toshinori is met with a swarm of adoring fans, much to his and Izuku's dismay. The interactions takes longer than expected, making Toshinori 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 Toshinori introduces Melissa to Izuku, and the two quickly get acquainted. Toshinori interrupts them when Melissa gets close to Izuku and notices his scars, reminding her of their agenda.
Toshinori 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 Toshinori's body, so he asks Melissa to show Izuku around the expo and give them some time alone. After they leave, Toshinori 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 Toshinori reassures him, saying that the Symbol of Peace is still alive. Toshinori shifts into his muscular form and leaves the lab, promising to meet David at the reception party.
At the party, Toshinori 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. Toshinori and the Pro Heroes at the party are restrained by powerful bond shots from the ground. David convinces Toshinori to comply with the villains and swears to find a way to save everyone.
Wolfram takes David and his assistant, Samuel Abraham, while Toshinori can't do anything as he watches. Toshinori then notices Izuku flashing light at him from the third floor, and Toshinori discreetly explains the situation. Izuku relays a message saying that Class 1-A and Melissa will disable the security system to save everyone. While Toshinori mostly disapproves, he puts his faith in his pupil and remains constricted on stage.
Toshinori had trouble maintaining his muscular form, but found an opening when Melissa disabled the security system, freeing him of his restraints. Melissa calls Toshinori and updates him on the stakes, and he promises to rescue Izuku and David. As Wolfram was about to escape with David Shield, Toshinori 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 Toshinori, but he is saved by Katsuki and Shoto, who are accompanied by the rest of Class 1-A. Motivated by their heroic spirits, Toshinori goes beyond his limits and breaks through Wolfram's iron defenses.
However, Wolfram uses his surprise Muscle Augmentation Quirk and metal wires to trap Toshinori. Toshinori is shocked, and deduces that Wolfram got his power from All For One. Toshinori'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. Toshinori 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. Toshinori 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. Toshinori says that Izuku isn't ready yet, but adds on that he has the potential to be the greatest hero.
==== Forest Training Camp ====
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, Toshinori 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 Toshinori that will allow him to locate the transmitter. Toshinori applauds Momo's growth and found her to be worthy of being a hero, asking her to leave the rescue of Katsuki to him.
==== Light vs. Dark ====
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. Toshinori and All For One clash, which creates a shockwave that sends Katsuki, Tomura and the Vanguard Action Squad backwards. Both All For One and Toshinori criticize each other for becoming weaker. Toshinori 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. Toshinori charges at All For One. However, All For One sends a huge blast wave at Toshinori, causing the Symbol of Peace to be sent flying away at great force. All For One's blast wave attack not only hits Toshinori but destroys several buildings in the process.
Despite being sent several miles away, Toshinori quickly recuperates and returns to the battlefield by jumping to it, refusing to allow All For One to escape and charges at him. Toshinori and All For One clash once again. Meanwhile, Katsuki is fending off some of the Vanguard Action Squad; Toshinori 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 Toshinori intervenes by punching All For One.
Toshinori 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 Toshinori himself is still surprised that Izuku and some of his fellow students came to rescue Katsuki. However, Toshinori 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, Toshinori 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 Toshinori's attack instead. All For One expresses his hatred for Toshinori as he is the one who brought down his comrades in the past and while he descended into darkness, Toshinori 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 Toshinori at the same time. However, Toshinori 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 Toshinori won't be able to fight at full strength. Furious with All For One's sadism, Toshinori grabs his arm while throwing Gran Torino away for safety. Toshinori admonishes All For One for all the despicable crimes he has committed and for his misanthropy.
Toshinori punches All For One in the face, shattering his mask; however, Toshinori's punch wasn't strong enough to finish off All For One. As Gran Torino calls out to him, Toshinori turns back into his true form. All For One says that Toshinori 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.
Toshinori 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, Toshinori prepares to attack All For One. However, All For One uses his blast wave technique against Toshinori, causing the Symbol of Peace to be blasted into the air. Gran Torino catches Toshinori and lands him to safety on the ground. Gran Torino advises Toshinori 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 to the entire world. All For One decides to sever the trust in Heroes once and for all. All For One once again expresses his hatred for Toshinori 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 Toshinori. Toshinori, 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, Toshinori 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 Toshinori's true form has been exposed for all to see.
Everyone around the country sees Toshinori's true form and begins panicking. All For One mocks Toshinori for the pitiful state he is in. However, Toshinori 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 Toshinori.
Toshinori refuses to believe, but All For One tells the Symbol of Peace that it is the truth. All For One wonders why Toshinori isn't smiling and sarcastically remarks about Toshinori's smile, which is something Nana would always do. Toshinori's spirit is greatly demoralized by All For One's sarcasm while All For One continues relishing in Toshinori's pitiful state. However before he could fall in complete despair, the innocent civilian under the rubble encourages Toshinori to win and help her.
Around the country, the people who are watching refuse to believe that Toshinori 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 Toshinori and encourage him to win. In response to this, Izuku and Katsuki also encourage Toshinori shouting at him to win. Invigorated by the civilian pleas, Toshinori regains hope as he activates One For All throughout the right side of his body, transforming it back into its Hero form. Toshinori smiles and states that Heroes have many things to protect which is why they don't lose.
Toshinori 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 Toshinori's appearance. Kamui Woods rescues Best Jeanist, Mt. Lady, and Gang Orca while Tora rescues the trapped civilian; Tora encourages Toshinori 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 Toshinori with his heavily empowered and mutated arm. While heading towards Toshinori, All For One knows from battling him that Toshinori no longer has One For All and tells Toshinori that the person who was given One For All by him is Izuku. All For One taunts Toshinori 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 Toshinori. However, Toshinori transfers One For All to his other arm, sacrificing his right arm but rendering Impact Recoil ineffective. Toshinori says that he must indeed criticize Izuku for his actions. All For One is shocked that Toshinori would go to such lengths to protect his leftovers of One For All and admits that he miscalculated. Toshinori 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.
Toshinori punched All For One, successfully hitting him. However, the punch Toshinori delivered was meant to lower All For One's guard which worked. Toshinori transfers One For All to his right arm and prepares for his final attack he will ever use. Toshinori 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.
Toshinori raises his arm to signify his victory; the reporter from the news helicopter announces All-Might's victory. Toshinori 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 Toshinori to preserve his strength, but Gran Torino stops him as he wants Toshinori 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 Toshinori and All For One's battle. Meanwhile, Endeavor and Toshinori watch All For One being placed in the iron maiden. Now that All For One is properly imprisoned, Toshinori points to the camera and delivers a message "you're next". The citizens watching take Toshinori'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 Toshinori'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 Toshinori's time has truly come to an end and starts crying.
At a hospital, Toshinori 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.
Toshinori wishes to find Tomura, however, Gran Torino tells Toshinori 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 Toshinori that he must remain at U.A. and carry out what he must still do; helping his successor, Izuku Midoriya.
Toshinori meets Izuku at the Takoba Municipal Beach Park. Toshinori greets Izuku with a Texas Smash to the face as a part of his scolding. Toshinori 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. Toshinori informs Izuku that he is retiring as a Hero since he is in a state where he cannot fight anymore.
Toshinori scolds Izuku for never doing what he is told and for his recklessness in rescuing Katsuki. However, Toshinori is glad that his recklessness did not get him injured this time and is proud of Izuku for that. Toshinori 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 Toshinori scolds him for again while some tears of his own begin to form.
==== U.A. Dorm Plans ====
Toshinori 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 Toshinori visit the homes of Class 1-A. He and Toshinori 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 Toshinori 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 Toshinori leave the Bakugo household, Katsuki appears and asks Toshinori what Izuku is to him. Unable to tell Katsuki the truth, Toshinori informs him that Izuku is a student to him who has great potential just like Katsuki. Satisfied to a degree with Toshinori's answer, Katsuki thanks Toshinori for everything and goes back inside his house. Shota decides to visit the other Class 1-A families by himself while Toshinori goes to visit Izuku.
Toshinori decides to visit Izuku's apartment by himself while Shota visits the rest of Class 1-A. Toshinori 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, Toshinori 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 Toshinori'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 Toshinori became a hero.
Izuku runs out of the room while Toshinori 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.
Toshinori is shocked that Izuku is willing to continue his dream even though it is not as the same place as his idol; Toshinori is impressed with Izuku's growth and is glad that he is going on his own path instead of following him, his idol. Toshinori transforms into his Hero form and kneels before Izuku and Inko, bowing his head, much to their shock.
Toshinori apologizes to Inko for his negligence as Izuku's teacher and understands that she is worried about the bloody path of a Hero; Toshinori 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. Toshinori promises that he will nurture and protect Izuku even at the cost of his own life.
Inko is shocked at Toshinori's resolve, causing her to fall to her knees. Inko states that all she wants is Izuku to be happy and tells Toshinori that he should never trade his life away for someone else's sake. Inko tells Toshinori 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. Toshinori pledges to protect and nurture Izuku while Izuku tells his mother that he will not worry her.
Outside, Toshinori compliments Izuku's mother, telling Izuku that she reminds him of his master. Toshinori leaves and tells Izuku that he will see him at U.A.
