Chapter 287

Nana Shimura remarks that running into All For One after death was not on her list of expectations. Izuku, recognizing her, works out where he is: inside One For All itself. Before he can think about the fight he left behind, All For One steers Tomura's attention toward the woman, identifying her both as his grandmother and as a corpse.

The explanation that follows reframes the whole Quirk. All For One recalls stories of transplant patients whose personalities shifted, and matches them to his own experience: dreams in which the voices of people he had robbed spoke back to him, leaving behind an unfamiliar residue of guilt. Handing a stolen Quirk off made the voice go quiet. Kyudai Garaki gave him the answer. Cells and organs carry the memory of whoever grew them, and a Quirk carries its user's individuality the same way. He believed himself alone in this until his younger brother, Yoichi Shigaraki, fused a stockpiling power with his own and inherited the same capacity for passengers.

Invited to say hello, Nana places Tomura as Kotaro's boy. He tells her that whatever chain of events dropped them in front of each other, he loathes her for what her son did to him. One For All begins eroding under his rage, which All For One reads as fury overwhelming a wielder's will, and which delights him, chaos being his own signature. The collapse stops. Yoichi has arrived, every bit as unyielding as his brother, and he asks whether Tomura is simply the latest in a long line of people All For One has steered.

All For One confesses he always wanted his brother for himself. Yoichi's answer is that none of them are coming, because they chose Izuku. Pushed back, All For One pulls Tomura's strength alongside his own and argues the case from the boy's own record: he could not shield his friend or his teacher, needed shielding himself, surrendered to anger, and now lies there twitching and watching. Passing the torch to someone like that, he declares, was a mistake.

Yoichi rejects it. A man who only ever manipulates cannot see what actually drives Izuku, whose rage belongs to other people and who keeps going until there is nothing left to give. He calls Izuku a boy consumed by a need to save that ordinary sense cannot account for, and says that is precisely why they follow him. An explosion tears the two apart in midair. All For One tells Tomura the theft failed because the new Quirk has not finished settling into him: reach completion first, retreat for now. Izuku begs him not to move.

Gigantomachia keeps grinding toward his master. Word that Tomura is trading blows with Endeavor reaches Dabi, who tells Skeptic to brace himself, because the counterfeit hero society is coming down. Mr. Compress catches Himiko Toga peering over the giant's edge and guesses she is hunting for the two people she loves. Her question to him is simpler and harder: where exactly do heroes draw their line, and if saving people is the job, was Twice not a person to Hawks? She wants to put it to Izuku and Ochaco directly, whether they would kill her, and says the answer, either way, will settle her.

All For One's vestige explains that stolen Quirks retain the personality and will of the previous holder, the same way a transplanted organ can, and that relinquishing a Quirk silences the voice attached to it. This is the mechanism behind the vestiges One For All's holders encounter.

The meeting with Nana is Tomura's first, and hatred is all he offers her. Yoichi Shigaraki intervenes to declare that Izuku is the rightful bearer of the Quirk, and the theft fails: Tomura's remodeling is only seventy-five percent finished, so All For One orders him to withdraw and heal.

News of Endeavor's fight travels to Dabi, who tells Skeptic to get ready to dismantle hero society. Himiko settles on her own question, whether the heroes who killed Twice would kill her too, and decides to ask Izuku and Ochaco herself.

Mistake runs seventeen pages and carries the number 287 in the series. Shueisha published it on October 12, 2020 in issue 45, and volume 30 collects it as part of the Paranormal Liberation War arc.
