The worlds were normal—until they weren’t.

At U.A. High, the sound of explosions shook the air. Bakugo charged at Midoriya, palms blazing. “I’M NOT LOSING TO YOU, DAMN NERD!” Midoriya countered with One For All crackling around him, his eyes sharp, determined. Todoroki watched silently, frost spreading across the ground as he tested his control.

Across Japan, at Jujutsu High, Yuji was in the middle of sparring with Megumi. “You’re too stiff, man!” he grinned, ducking under a strike. Megumi frowned, his shadows twitching with irritation. “You’re too careless.”

In the Clover Kingdom, Asta’s shouting echoed as he swung his massive sword. “I’LL SURPASS MY LIMITS RIGHT HERE!” Yuno stood calmly nearby, his grimoire glowing faintly, the quiet foil to Asta’s endless noise.

Meanwhile, in the forests of Taisho-era Japan, Tanjiro adjusted his stance, sword steady, while Inosuke crashed through the trees with a roar. “BRING ME SOMETHING TO SLASH! I’M GETTING BORED!” Zenitsu lagged behind, trembling but keeping up, thunder breathing buzzing in his veins.

On the walls of Shiganshina, Eren clenched his fists, eyes burning with restless fury. Armin stood beside him, lost in thought, while Levi’s cold stare swept the horizon. “Stay alert. You never know when everything goes to hell.”

And then it did.

The skies split open. A violent void tore across every world, ripping them apart. Winds howled, the air itself screaming as black rifts pulled at the fighters. Resistance was useless. They were dragged upward, their shouts echoing in the chaos.

In the blink of an eye, they crashed together in a new land. Dust billowed, bodies slammed into the earth, and silence hung for only a second before the shouting began.

Bakugo shot to his feet first, fury in his eyes. “WHICH ONE OF YOU EXTRAS SCREWED WITH MY TRAINING?!”

Yuji groaned, rolling over. “Man… that hurt. Where even are we?”

Inosuke bounced up like nothing happened, slamming his swords together. “HA! NEW ENEMIES! FINALLY!”

Tanjiro tried to calm him, though his eyes were wide with confusion. “Wait—these aren’t demons… they’re…”

Levi stepped forward, brushing dirt from his uniform, his tone flat but sharp as a blade. “Tch. Wonderful. A bunch of idiots from god-knows-where dropped out of the sky. Just what I needed.”

Eren’s eyes narrowed, shoulders tense. “Who are all of you?”

The multiverse had collided—and none of them were ready.
