Heroes and villains lie scattered across the debris, too wounded to move.

And in the center of it all — All Might, broken and bloodied, held up by All For One, one massive hand gripping his throat.

The Symbol of Peace is fading. His last embers flicker in the wind.

All For One (smirking): “Your time has ended, Toshinori. The world doesn’t need a dying flame.”

He raises his other hand — black energy spiraling around his arm, forming a spear of destruction meant to end everything.

Students of U.A., battered from the earlier battle, watch helplessly from the sidelines. Midoriya can barely move. Bakugo groans, his wounds barely sealed, thanks to one person —

Jinnie.

She’s kneeling beside Bakugo, hands glowing softly, her voice trembling as she sings the healing hymn of her Quirk’s angel form. Light gathers over his chest wounds, sealing the burns.

Bakugo: “Damn it… he’s gonna kill him…” Midoriya: “We can’t… move fast enough…”

Jinnie’s voice falters. She looks up — and sees All Might lifted high in the air like a dying flame.

Her heart stops.

Inside her, something screams.

The tattoo on her arm begins to burn — a seal breaking.

Jinnie (whispers): “Not again… not here…”

But the pressure rises. The world seems to darken around her. Bakugo notices her trembling hand.

Bakugo: “Hey. What’s with you?!”

She doesn’t answer. Her eyes widen — glowing red and gold at once.

And then—

The air explodes.

A shockwave of dark fire bursts from her body, knocking debris and light aside. The ground cracks. Her uniform tears at the back as something enormous forces its way out.

Two wings — vast, black as void — unfurl from her back, each feather rimmed with embered flame.

Her brown hair now streaked with silver and crimson. Her once warm eyes burn like suns of damnation.

The students stare in horror.

Uraraka (gasping): “Her… her Quirk—what is that?” Midoriya: “That’s not a Quirk I’ve ever seen before…” Bakugo (grimly): “…Tch. I knew there was something off about her.”

All For One turns his head, sensing the spike of energy. His grin falters.

All For One: “That… power… it doesn’t belong to this world.”

Jinnie rises slowly, her voice layered — half angel, half demon.

Jinnie: “Let go of him.”

All For One laughs, tightening his grip on All Might.

All For One: “And who are you to give orders, little girl?”

The sky darkens completely. The ground trembles.

Jinnie (softly): “I am the thing even Hell fears.”

In a blur, she vanishes — faster than even Gran Torino could follow — and reappears behind All For One.

Black fire ignites her hand, forming a dark blade. She slashes once — a shockwave of infernal energy tears through the battlefield.

All For One staggers back, his arm burning, regeneration struggling against the unnatural flames.

All For One: “What… is this Quirk?!” Jinnie (quietly): “It isn’t a Quirk.”

She catches All Might as he falls, her dark wings folding protectively around him. He looks up weakly — eyes widening at the sight of her monstrous form.

All Might: “Young… Jinnie…?”

For a moment, her demonic glare softens.

Jinnie: “Stay still, All Might. I’ll end this.” *puts all might down next to bakugo.

All For One attacks, sending tendrils and kinetic blasts, but Jinnie’s black flames consume them, her wings deflecting shockwaves like shields.

The world shakes as light and darkness collide — the Symbol of Peace saved by something no one expected: Not a hero, not a villain, but a girl cursed with both Heaven and Hell inside her.
