Izuku races toward the memory just as Kotaro starts abusing the shadowy, childlike form of Tenko Shimura—the moment that sets Tenko on the path to becoming Tomura Shigaraki. But Izuku is suddenly thrown back by an invisible wall made from the last bits of mental armor guarding Shigaraki’s origin. He pushes with everything he has, but the memory keeps playing.
Kotaro coldly tells his son that Nana was nothing but a brute who abandoned her family—no different from any Hero who hurts the people closest to them just to save strangers. Hearing this, Nana breaks down. She realizes Kotaro kept her photo not out of love, but because he couldn’t bring himself to toss it away. She blames herself for creating the cycle of hatred that eventually consumed her grandson, and for failing to defeat All For One when it mattered most.
From a distance, Izuku calls out to her as Kotaro raises his hand to hit Tenko again. Nana wipes her tears, apologizes for her weaknesses, and forces herself to stand tall. Then she charges straight into the barrier, shattering the remaining armor and breaking through in time to stop her son from hurting his child again.
Nana’s vestige disappears
With the last piece of One For All finally destroyed, Nana’s vestige begins to crumble. She apologizes to the memory of her son for never coming back, then turns to her grandson as the void around him breaks apart, revealing a young, frightened Tenko.
As Nana’s presence fades, she gives Izuku one last smile, and he nods back. With her gone and the core of their enemy reached, One For All disappears for good. Now everything rests on Izuku and Tenko.
AFO takes over Tomura’s body
The two return to the dark, empty house—until a giant, twisted version of All For One’s scarred face erupts from the ground, dragging Tomura down and throwing Izuku across the room. With Tomura’s mind weakened, the All For One side inside him seizes control. In a distorted voice, he tears into Tomura, mocking him for letting someone he calls a “nobody” get inside his head.
A massive construct of All For One’s suit forms around him as he drops a devastating truth: every single thing Tomura has lived through was orchestrated by him. He even turns on Izuku, demanding to know why he destroyed One For All and Yoichi’s essence with it. Tomura insists he acted of his own free will, but All For One tells him that belief is the only reason he had any will at all.
AFO’s convoluted plan
Once Tenko is born, All For One immediately starts putting his long-term plan into motion. He secretly steals the baby’s still-undeveloped Quirk Factor, then uses his growing relationship with Kotaro to push the man’s frustration with Heroes and Nana into full-on abusive behavior toward his own kids.
Later, he arranges for Mikkun and Tomo to hang out with Tenko. During one of their playdates, Tenko ends up saving them from an incoming truck, planting the idea of heroes in his young mind. That same day, All For One walks Tenko home, and when the boy grabs his hand, the Villain quietly passes on the Quirk that will become Decay—a modified version of Overhaul without its healing abilities.
Tomura fractures
Back in the vestige world, All For One tells Tomura to get out of “his body.” Tomura starts panicking and scratching at his neck before his vestige completely breaks apart. With Tomura erased just like All For One planned, the vestige world collapses. In the real world, Tomura’s body suddenly explodes, wiping out what’s left of the forest and leaving behind a barren wasteland.
Among the ash, the extra mutated fingers crumble away. With his connection to Tomura finally gone, “All For One” adjusts to his new body, now smooth and lifeless gray. He can still hear Tomura screaming in the back of his mind, so he reshapes his lower face into a black-and-red version of the hand mask Tomura used to wear, silencing him for good. With no One For All to chase and no successor left, “All For One” is free to focus on the only goal he has left: creating a world entirely his own.
Class-1A to the rescue
Out in the wastes, Deku is the last one still standing in front of “All For One,” but he can’t get up no matter how hard he tries. He’s completely spent, and the damage he brought back from the vestige realm is brutal—his forearms are gone, just two bloody stumps left over from his fight with Tomura. Even with his body basically broken and the enemy ready to finish him off, Deku refuses to quit. “All For One” walks up, aims an Air Cannon at his head, and prepares to end it.
Right then, Danger Sense activates. Before “All For One” can react, tape whips around his arms and torso. Cellophane appears out of the dust—he somehow made it to the battlefield. And he didn’t come alone. Tailman and Sugarman rush in and knock the villain to the ground with Tornado Tail Dance and Sugar Knuckle. Deku is shocked to see his classmates alive and okay. A Warp Gate opens behind him, and Eraser Head steps out, apologizing for the late backup.
Eri steps up to help
We then learn that before they deployed, Eri stopped Eraser Head and handed him a piece of her horn—snapped off with help from Ectoplasm. She asks him to bring it to Deku so he can rewind his injuries, since she knows she can’t come along. Eraser Head scolds Ectoplasm, but Ectoplasm insists Eri was thinking clearly and making her own choice. Eri knows even a piece of her horn can trigger Rewind, though Eraser Head is worried she damaged her Quirk doing this.
Eri doesn’t care. She says she couldn’t help All Might and Dynamight before, and she won’t miss another chance. She tells him her dream is to sing for everyone once the fighting is over, because Deku and the others brought so much joy back into her life. Even if she can’t fight directly, giving up her horn is how she can help—so she wants Eraser Head to accept it. He finally does.
the Final Fight
In the present, portals start appearing all over the battlefield as Eraser Head rushes to Deku’s side. He checks on him and asks how long it’s been since his arms were destroyed, but Deku can’t give an answer with how warped time was in the vestige realm. Not wasting a second, Eraser Head pulls out Eri’s horn and taps it against Deku’s shoulder. Rewind activates, turning his body back a couple minutes. Deku’s arms return—scarred, but intact—thanks to everyone backing him up.
Surrounded by his friends and allies jumping in to help, Deku holds back his tears and steadies himself. With his resolve restored, he locks onto All For One, ready to end the long fight between Heroes and Villains once and for all.
