Mumen Rider in MHA

Kamino Ward burned.

Smoke rose in oily black spirals, curling through shattered windows and crumbling concrete. Emergency sirens wailed in every direction, and the light above was a dull red cast from fires reflecting against low-hanging clouds. Somewhere behind the chaos, a drone buzzed low, relaying a nationwide broadcast.

And in the heart of the wreckage, two titans faced each other.

All Might stood panting, bloodied and bruised, the embers of his dwindling power flickering around him like dying stars. Across from him, All For One loomed—unbothered, unbroken, monstrous.

A dozen tendrils writhed from the villain's back, slick and black like oil-soaked vines. They slithered across the ruined ground, rooting through debris, dragging twisted rebar and chunks of asphalt from the earth like skeletal fingers clawing from a grave. One snapped through the air and coiled around a nearby drone, crushing the camera lens into sparks before flinging it aside like garbage.

Then—faster than the eye could follow—several more lashed forward.

All Might barely turned when they struck.

Three wrapped around his torso. Two more tangled his arms, forcing them back with sickening force. The last coiled around his leg, yanking him down and slamming him hard into the shattered concrete.

Dust billowed upward.

All For One's grin widened behind his mask as he stepped closer, the tendrils pulling tighter, binding All Might like a monument to failure in the heart of the crater.

"This symbol," All For One said, his voice echoing across speakers nationwide, "has cracked."

He turned slowly—deliberately—toward the edge of the plaza where rubble had once been a shopfront. And there, pinned beneath fallen beams and twisted signage, lay a woman and a girl.

Kana coughed weakly, smeared with dust and blood. Her mother's head lolled, unconscious.

The drone's lens zoomed in. The world watched.

All For One extended a hand toward them.

All Might screamed. He tries to move—

And across the city, in every bar, shop, living room, hospital, and alley, people held their breath.

The villain's palm lit with gathering energy.

"Let this mark the end," he said. "Not just of All Might. But of what he failed to protect."

Kana stared up at him, her eyes wide—

A tendril coiled tighter.

Then—

VROOOM—CRASH!

A streak of green and silver roared through the smoke—a bike, its rider hunched low, moving like a bullet.

The bike slammed into All For One's side with a shriek of metal, throwing him several feet and interrupting the blast. Rubble exploded outward. The drone feed went static for a second.

When it cleared, a figure stood in front of Kana and her mother.

Goggles cracked. Armor dented.

But unshaking.

Mumen Rider.

He raised one arm slightly, barring the path.
