Boku no Hero Academia

Deku and the Top Three Heroes, plus The Lurkers, confront All For One at his hideout in Haibori Woods, only to find it abandoned. A recording left by All For One taunts Deku for his failures, telling him it's "his turn", before setting the mansion to explode. The Heroes escape and reconvene to discuss their options, due to the dwindling amount of Heroes left available. Meanwhile, Deku swiftly deals with the second hitman, while All Might desperately attempts to convince him to rest. Deku believes that since he can use practically use One For All at 100% without backlash, he doesn't have to watch over him anymore, and All Might can only look on devastatingly as Deku flies away, leaving him behind. Over the next several days, Deku proceeds to tirelessly travel through the city, saving whoever he can, ignoring the Heroes and the One For All predecessors' advice to take it easy. Because of this, Deku starts taking on a more monstrous appearance, with civilians scared of him and rumours going around that he is a Nomu, yet he refuses to stop, all so that he and everyone he cares about can smile again. He begins to collapse in Kamino where he confronts another hitman, Dictator, who uses his Quirk to attack Deku using nearby civilians. Due to being too tired, Deku is unable to fight and is swarmed by the mob, until he is saved by Bakugo who knocks Dictator out. After having received Deku's letters, Class 1-A figured out that Deku and All Might were working with Endeavor, and use Nezu to summon him to the school to confirm this. They state their desire to help their classmate in his moment of need and Nezu approves of them going out onto the streets to bring him back. Class 1-A confront Deku, who refuses to give in and demands they get out of his way, preparing to fight.

Deku attempts to escape from his classmates, so they all try to restrain him. During their struggles, each Class 1-A student reminds Deku of something he had done for or said to them in the past, and how much their friendship means to them, but Deku refuses to listen, not wanting them to be caught up in his battle against All For One and get hurt, as his way of "protecting" them. After almost every one of their attempts to talk or pin him down fail, Deku prepares to execute Faux 100 Percent to blast himself away for good, but Class 1-A combine all of their abilities to create a massive ramp which they use to blast Iida into the sky at blistering speeds, catching up to Deku and grabbing his hand. Iida repeats what Deku had said to him in the past when he saved him, that helping without being asked is the essence of a hero, causing Deku to start to give into his exhaustion. On the ground, he once again tries to keep his distance from everyone, but Bakugo confronts him, admitting the reason behind why he bullied him in the past. He sincerely apologizes for everything he said and done, telling him the class doesn't want to reject who he is, but support him to help save everyone. Deku finally gives in and apologizes himself before passing out. He wakes up in front of the now heavily fortified U.A., only to be met by a mob of angry civilians demanding Deku not enter, aware that he is the boy Shigaraki is after. Deku is about to leave, but is stopped by Ochaco.

Prior to rescuing Izuku, Nezu explained to Class 1-A the intricacies designed into the U.A. Barrier to keep it fortified from villains and to protect the civilians inside. In the present, the civilians protest Izuku's entry, believing his presence will put everyone in the school in danger. Best Jeanist tries to explain everything to get them to understand, but his words only make the crowd even more anxious over the Heroes' failures, stressing Izuku out. Ochaco then grabs the megaphone and floats on top of U.A., giving a speech pleading to the civilians to let Izuku rest because Heroes deserved to be saved too. As a result, the civilians start to see how battered and tired Izuku is, and by the end of her speech, Izuku breaks down on his knees in tears. He is comforted by Kota and the mutant woman he saved earlier. One of the civilians speaks out to the rest of the crowd, admitting how much like bystanders they have been in their treatment towards the Heroes and that they should be doing their part to help in some way. After Izuku declares he will bring the world back to the way it was, the civilians accept him as he is escorted inside. Meanwhile, Nezu speaks to a recovering Aizawa in the Central Hospital, revealing that they had transferred Kurogiri to the location after the discovery of him being Shirakumo's Nomu, attempting to re-awaken him. Outside U.A., All Might leaves to find more civilians, thinking about his influence Izuku's current state, all the while Stain continues to follow him.

All Might arrives at the site of his final battle in Kamino, lamenting his failure as a teacher and a hero, when he is confronted by Stain. Even after briefly revealing to him his muscle form to confirm his identity, Stain refuses to believe he is the "real All Might", and to take back his criticisms towards the hero. All Might explains his feelings on unable to make a difference due to the state of the world, only for Stain to show him a young girl who has been going out everyday to clean the All Might statue from its vandalism; the last person All Might saved during said battle. Stain tells him it wasn't power that made All Might great but his ability to inspire others and their wills to keep his flame burning, these words which start to move All Might. Stain promptly leaves, handing All Might a data disk he had retrieved from Tartarus, telling him to kill him when the time is right. At U.A., the boys give Izuku a swift soak in the bath, where Bakugo re-declares even after his apology, he still sees everyone has his rivals. After their clean-up, All Might arrives to apologize to Izuku, telling everyone they received information indicating the final battle is soon, heading back out to prepare. Izuku finally falls asleep and the rest of his classmates declare they will do everything to bring the world back. All Might meets up with Tsukauchi and the Police Force where they decode the information from Tartarus. They discover that All For One's consciousness within Shigaraki was able to communicate with his real self through Radio Waves, with the conversation revealing that Shigaraki's body will be complete in just three days. All Might requests immediate aid from the foreign heroes, with the world governments unsure how to respond due to their own issues. Despite this, America's Number 1 Hero, Star and Stripe, heads to Japan on her own with an army of fighter jets, intending to assist her "master". Shortly afterwards, Izuku wakes up from a nightmare, greeted by his classmates, whose presence helps relieve him of his stress, intending to save the day together.
