During the final war between Heroes and Villains, Deku made a single mistake—one that cost them everything. He focused too much on defeating Shigaraki, pushing himself past his limits, rather than protecting his friends from the wave of villains swarming the battlefield. That one choice shattered the heroes’ final stand. Their allies fell one after another, slaughtered or dragged away in chains, until only a few remained scattered in the chaos. In the end, Deku himself was overwhelmed, his broken body collapsing under Shigaraki’s grasp. All For One stood victorious, seizing his chance to capture Deku alive. Now, he keeps him prisoner—not to kill him, but to torment him, to break his spirit piece by piece.

With their leader triumphant, All For One’s forces swept across Japan. Cities fell quickly, their resistance crushed in days. He declared himself ruler, ruling with an iron fist, while sending armies to invade neighboring countries. Each passing day, his control grows, and hope dwindles. Most heroes are either dead, turned into Nomu, enslaved, or forced to flee into the shadows as broken wanderers. The world they once fought for has been reduced to ashes.

UA, once a beacon of hope and training for young heroes, has been twisted into something unrecognizable. Now it stands as a brutal military camp where teenagers from Musutafu and Tokyo are dragged, brainwashed, and trained into weapons for All For One. The pro heroes who once taught them are gone—slain one by one. Even All Might himself was struck down, his body left as a warning for anyone who dared resist.

And yet… a few survived.

Class 1-A is not completely gone. Against all odds, a small group managed to escape the slaughter, abandoning their old lives and retreating into the wilderness. They hide in ruined shrines, abandoned barns, or the deep forests of Japan, moving constantly to avoid patrols. Mina clings to her optimism but struggles to hide the fear in her eyes. Ochaco tries to lift everyone’s spirits, whispering words of comfort around the campfire, though her voice trembles. Aoyama forces a smile, pretending everything is fine, but his hands shake whenever the silence drags too long. Jiro keeps her ears sharp, straining for the faintest sound of enemy movement. Kirishima pushes himself to be strong, to encourage the others, though his armor has cracks both inside and out. Denki tries to joke and lighten the mood, but the laughter always dies quickly. Ojiro watches the group quietly, protective, ready to leap at any threat. And Sero… Sero keeps tying scraps of rope and tape, restless, as if reminding himself he’s still useful.

Among the pros who escaped are Endeavor, who burns with guilt over his failures but refuses to fall; Mirko, still fierce, though scars cover her body; Ms. Joke, whose once cheerful nature is now laced with bitterness; Eraserhead, tired and hardened, keeping everyone alive with grim determination; and Present Mic, who has lost much of his sanity, his voice cracking between manic shouts and quiet despair. Together, they cling to survival, though every day feels like their last.

And you… You were once part of Class 1-A. But now the world has changed. You must decide: What have you become? Did you flee with your classmates into the wilderness? Did you stay behind and risk capture? Or perhaps you walk a darker path, serving the enemy to stay alive? In this ruined world, your choices will determine not only your fate—but the fate of the last spark of resistance against All For One.
