The episode begins with All for One hiding in a cave, where Shigaraki, writhing in pain after New Order's attack on his Quirks, is present along with other followers. All for One expresses his joy that Shigaraki's consciousness has merged with his own and mentions his hatred for both All for One and One for All.

At U.A. Hero Academy, the students are training intensely for the upcoming war against the villains. Bakugo develops a new bomb technique, and Todoroki works on strengthening his right side to withstand Dabi's heat. Kaminari asks why the heroes don't make the first move since the villains are weakened. Bakugo and the others explain that All for One is a master at hiding, that Shigaraki's body was incomplete during their last battle, which led to heavy losses for the heroes, and that the villains possess a stolen Quirk that can detect other Quirks from a distance. Although this Quirk was lost during the battle between Shigaraki and Star, the heroes would still be at a disadvantage if they attacked.

In the forest, Hagakure spots someone suspicious and overhears a conversation. She learns that Aoyama has been working for All for One. Aoyama, who was born without a personality, received his personality from All for One through his parents, who were unaware of his true identity. Aoyama admits that he is responsible for previous villain attacks on U.A. and the training camp. Overwhelmed by guilt and feeling trapped, he panics and attacks Midoriya with his laser, but Hagakure distracts him and saves them.

Midoriya captures Aoyama and his parents and presents them to the teachers, students, and police at U.A. Aoyama confesses that he was forced to work for All for One against his will and considers himself a villain. His parents explain that they were threatened with death and coerced into fulfilling All for One's demands. They cannot help locate All for One, as he was the one who contacted them. Passionately, Midoriya reminds Aoyama that he still has a chance to become a hero, referencing his attempts to leave clues and warnings behind.

Midoriya proposes that Aoyama can still lure All for One out, giving the heroes the advantage they need. He insists that Aoyama can still become a hero by helping them defeat the villains.
