Class 1A (with the exception of Kyoka, Tora and Mom) visits Izuku in the hospital where he cries about his failure to save Bakugo. That's when Shoto says "Let's save him, Bakugo I mean." "I overheard them talking about where the tracker leads. What? I may not like the guy but he doesn't deserve this." Eijiro said "No, we can't save him. Let's leave it to the professionals." Tenya said, the two of them (Eijiro and Tenya) argue. That's when Eijiro said "Izuku you agree with me, right?" Only for Yuga, Fumikage, and Tsuyu to say "We should leave this to the professionals." Then an awkward silence follows that is only broken when Izuku's doctor, Recovery Girl coming in "I need you guys to leave us alone for a minute." She says "Meet me behind the hospital after dark" Eijiro says to Izuku, after they (the people who visited Izuku) leave Recovery Girl says "We're lucky that they allowed me to be your doctor, so the secret still under wraps." Then gives Izuku a thank you note from Kota. On the roof Izuku reads the note and then gets a call from his mother who says "Do you really need to return to U.A, we can try another superhero school. If not for you then the babies." "Mom, you don't have to worry about the babies anymore, Recovery Girl said that I have a defense system that has been protecting the babies all this time but they're only five more times I can use it. Think about all the good I can do with it." Izuku said, only for his mother to say "That's what I'm talking about, that kind of thinking came from U.A." Only for Izuku to say "Mom, be real. You know me and I would've done that with or without U.A, with them I don't have to use them because they been protecting me." "Like when your camp got attacked by villains, where were they then?" His mother asked, only for Izuku to respond with "Protecting me with everyone else, look they might've not been able to stop the incident but they made sure we were safe when it happened." "But not all of you are safe, what about Bakugo?" His mother asked, only for Izuku to respond with "Don't worry about Bakugo, we have a plan to save him." "We? What do you mean by we? What are you planning to do? What..." His mother said only to be cut off by Izuku hanging up.
Eijiro asked Momo to make a new receiver for the tracker which she does. Eijiro, Momo, Shoto and Izuku then met up behind the hospital where they are confronted by Tenya who says "How could you guys do this, aren't you at all thinking about the reputation of U.A. Didn't you at all learn from my incident in Hosu?" "But we have to save Bakugo and ah." Izuku said when Tenya almost hit Izuku in the face "Your lucky I don't hit pregnant people." Much to Momo's and Eijiro's confusion, only for Shoto to say "Izuku's pregnant but we must keep it a secret, so shush." "Ah, I knew something was off with him." Momo said referring to Izuku. "Sorry, I really needed to get that off my chest. Now back onto the important issue, I'm just worried about you guys getting hurt. Your injuries Izuku, they remind me off Tensei's and you guys could get hurt even worse trying to save Bakugo." Tenya said "Don't worry, we'll save him covertly rather than fighting the villains head on." Shoto said, only for Momo to say "I'm joining up with you guys." "As long as Bakugo's in reach, I can't help but want to save him." said Izuku, only for Tenya to say "Okay, I'm joining you." "Okay, let's go." Izuku said, only for Eijiro to say "Wait, shouldn't you stay behind Izuku with the whole being pregnant thing." "Oh, no. It's cool you see I have this tracker here that tells me how much I can use my quirk before it hurts the babies besides, I just learned my quirk comes with a defense system that'll will protect the babies but I only have five more uses of it." Izuku said only for Eijiro to respond with "Oh, wait are you saying you have a second quirk that has nothing to do with the first?" "Why is it so shocking? So do I technically but no one questions me." Shoto said, only for Izuku to say "It's a long story which I will tell you after the mission."
Meanwhile with Tomura "So you like to win, how about I tell you a different way you can." Tomura says, only for Bakugo to say "I'm listening." Then Bakugo notices the broadcast "Bakugo wild side is a result of his tenacious pursuit to be the best hero." Aizawa says on the broadcast, getting Bakugo to change his mind "Huh, they understood me better than I thought and as for you guys. You can go to hell because I'm not becoming a villain, I'm becoming the number one hero and nothing can stop that." Bakugo said
They (Izuku, Momo, Shoto, Eijiro and Tenya) bought and put on disguises. Momo leads the group to what they believe to be the villain's hideout. None of them have effective stealth skills, so they ponder their next move. Izuku starts to mutter and Tenya thinks about how he needs to keep the group out of trouble. Izuku and company remain outside the second evil lair. They decide to go around the back and use Eijiro's night vision goggles to see through a window. Eijiro and Izuku scout the building and are frightened when they discover its a factory for breeding Nomu. Izuku and the others are stricken with fear by the appearance of none other than All For One himself who is captured by Best Jeanist. Well he tries to at least but All For One causes an explosion but Best Jeanist saves himself and the others from the explosion. All For One commends Best Jeanist for saving himself while protecting the other heroes from the explosion. Best Jeanist recognizes the masked man as the suspected ringleader of the League of Villains. The Pro-Hero attacks, but All For One easily defeats him with a blast of air. The villain recognizes that his strength comes from practice and experience and decides his Quirk doesn't need to be taken. Izuku, Shoto, Momo, and Tenya are stricken with fear while hiding behind a wall. All For One transports the villains to him and tells Tomura that it's time for his game to be reset. Izuku wants to try and move from behind the wall, but Tenya stops him. Before All For One notices the students, All Might suddenly arrives and confronts All For One. All For One commends Best Jeanist for saving himself while protecting the other heroes from the explosion. Best Jeanist recognizes the masked man as the suspected ringleader of the League of Villains. Best Jeanist attacks, but All For One easily defeats him with a blast of air. The villain recognizes that his strength comes from practice and experience and decides his Quirk doesn't need to be taken. Izuku, Shoto, Momo, and Tenya are stricken with fear while hiding behind a wall. All For One transports the villains to him and tells Tomura that it's time for his game to be reset. Izuku wants to try and move from behind the wall, but Tenya stops him. Before All For One notices the students, All Might suddenly arrives and confronts him. Katsuki notices All For One's raw strength and notes that he must be the strongest villain. All Might tells his ultimate rival he will defeat him and lock him up for the rest of his life. All Might rushes him, but All For One repels him with an enhanced Quirk combo attack. All For One tells Tomura to get Katsuki and flee the battlefield. Then he reaches Kurogiri's body and forcibly activates his Quirk to create a Warp-Gate. All Might returns and clashes with the masked ringleader while the remaining villains surround Katsuki. All Might can't get past All For One to rescue Katsuki. The student uses his explosions to keep the villains at bay while keeping his distance. Izuku worries that Katsuki won't be able to evade them for long. He mulls over the fact that heroes in training can't fight the villains until he realizes there's another way to rescue Katsuki. All Might continues to scuffle with his nemesis while holding back to protect Katsuki from potential shockwaves. Katsuki knows that All Might can't go all out because of his presence. Katsuki gets rescued. Izuku puts his plan in motion while Katsuki has some distance between him and his enemies. Izuku and Tenya grab onto Eijiro and use their Quirks to quickly break through the wall with Eijiro's hardening. Shoto creates an ice ramp for them to charge upward off of and into the air. All For One tries to interfere, but All Might is there to attack him. After clearing the battlefield at a great distance from the ground, Eijiro calls out to his Bakugo. Katsuki listens to his Eijiro and uses a giant explosion to propel himself through the air and grabs onto Eijiro's hand. Using her Quirk, Magne tries to propel Mr. Compress at the group of fleeing kids. Mt. Lady uses her Titan Cliff technique to grow in size and impede his path. Magne tries to do it again, but Gran Torino arrives and knocks them all out. Gran Torino points out Izuku's actions and compares him to Toshinori. All Might tells All For One he's finished holding back. Gran Torino prepares to fight Tomura and Himiko. All For One forcibly activates Magne's Quirk and magnetizes all the male villains to Himiko, pushing them all through the gate at once. Alone to fight, All For One repels All Might's next attack by warping Gran in front of it. All Might recovers and grabs Gran Torino before he unleashes a Detroit Smash to counter All For One's spring-like limbs Quirk. All Might destroys All For One's mask. All For One points out that All Might is still holding back because of the bystanders nearby. All Might angrily declares that he will not let All For One's disrespect of the common man continue and crushes his helmet with a powerful strike. However, All For One survives the attack. All Might begins to partially revert to his weak form and All For One says All Might's declaration is similar to his predecessors: Nana Shimura. Shoto and Momo escape safely from the battle zone and Shoto speaks on the phone with Izuku. Bakugo refutes the idea that he was rescued and points out that he only escaped with his peers so he could get out of All Might's way. Izuku ponders if they were correct to leave the fight to All Might alone. All For One taunts All Might about being too similar to his weak predecessor. He provokes All Might into striking with anger and then uses an opening to blast the hero away with an air cannon blast. All Might nearly crashes into a media helicopter but Gran swoops in to rescue him. Gran reminds All Might that All For One's taunting is what distracted All Might the last time they fought. Ochaco, Yuga, Fumikage, Tsuyu, Minoru, Vlad King, and Aizawa among others watch the horrifying broadcast of All Might's bout. All For One says that he feels conflicted about landing the finishing blow to hero society after his protégé worked so hard to ruin it. He goes on to say that he despises All Might because he ruined everything the villain has built up since the beginning of his reign. All For One charges up another attack. Gran Torino orders All Might to evade, but the villain aims for a nearby civilian trapped underneath debris. All Might defends the civilian by taking the brunt of All For One's air cannon. Despite being weakened, All Might remains steadfast. All Might's body reverts completely back to its weak form, revealing this body to the public for the first time. All For One claims he'll destroy All Might's reputation by exposing his weakness. All Might replies that in spite of his body's weakness, he remains the Symbol of Peace within his heart. In an effort to break All Might's will, All For One reveals that Tomura Shigaraki is actually Nana Shimura's grandson. All Might struggles to believe it and All For One taunts him about smiling all the time. All Might thinks back to when Nana taught him that the strongest people are always smiling, but he begins to break down after thinking about if Nana could see Tomura's evil. "Win, All Might!" All Might begins to despair, but the civilian he saved earlier encourages him to win. Everyone watching the battle begins to worry about All Might's chances of victory. Desperate, citizens cheer for All Might. Even Izuku and Katsuki scream for All Might to win. With his confidence restored, All Might charges One For All into his arm and tells his nemesis that heroes have too much to protect and that's why he won't lose. All Might thinks back again to some of his master's advice. She tells him to remember his origin and by doing so he can go beyond his limits. Gran watches from a distance. He worries that enduring so many of All For One's powerful attacks has taken too much of a toll on his body and his Quirk. All For One levitates above All Might and prepares to blast him. Endeavor and Edgeshot rush in to back up their ally. Endeavor is enraged by the site of All Might's weak form. All For One is impressed that the Flame Hero was able to do away with all the Nomu. Endeavor yells at All Might, demanding that the Number One Hero show why he's the best. All For One tries to attack Endeavor and Edgeshot rushes in to stop him. Kamui Woods arrives and rescues the injured Pro-Heroes. He commends Mt. Lady for her efforts. Tiger recovers and encourages All Might to win because no matter his appearance, All Might is still everyone's Number One Hero. Gran recalls speaking to Nana about Toshinori's desire to become the pillar of justice and peace. He thinks to himself, knowing that All Might has become that pillar. Everyone watching this scene still believes that All Might can win and they continue to pray for his victory. Annoyed with the heroes' resistance, All For One blows Edgeshot and Endeavor away. Then he uses his ultimate combination of Quirks to create a powerful arm he plans to crush All Might with. The villain reveals that he knows All Might has passed One For All to Izuku, and that he is only utilizing the embers of One For All. All For One attacks and All Might matches him with his enhanced arm. The villain says that All Might has no control over his student and will die full of regrets. All For One uses Impact Recoil to push All Might back until the hero replies that he must live to reprimand Izuku and do for his student as Nana did for him. All Might focuses One For All in the opposite arm and allows his enemy to injure his right arm so that he can close the distance between them. The Symbol of Peace punches his nemesis and breaks off more of All For One's mask. All For One states that tricks like that aren't normally in All Might's arsenal and that's why his attack was weak. All Might refutes that and explains his back simply wasn't in it. The Symbol of Peace concentrates the remaining embers of One For All into his fist while remembering the time Nana officially passed the torch to him. All Might finishes All For One with one final epic technique: United States of Smash! All Might triumphantly raises his fist in victory. Onlookers cheer with excitement and repeat the name of their favorite hero. All Might bids farewell to One For All and enters his muscular form one last time. Edgeshot says All Might shouldn't push himself, but Gran explains that his job isn't over. As the Symbol of Peace and Justice, All Might must reaffirm the faith in heroes for the common people. Afterward, heroes arrive and conduct rescue operations. All For One is arrested and All Might points to the camera and delivers one last message. He says "Your turn next". The average person believes this to be a warning to criminals. However, Izuku knows that All Might can't use One For All anymore and his legacy is left to his protégé.
