Humanity's greatest heroes never imagined the apocalypse would arrive like this.

Without warning, the Earth was ripped apart as entire cities collapsed into a colossal, ever-changing Dungeon stretching far beneath the surface. Billions died in the catastrophe. Those who survived became unwilling contestants in an intergalactic reality show watched by trillions of alien viewers.

In this new world, Quirks alone are no longer enough. Every survivor receives levels, classes, skills, achievements, inventories, and magical equipment. Strength must be earned floor by floor as the Dungeon grows increasingly deadly and unpredictable.

Musutafu and U.A. High have become one of humanity's remaining strongholds, where heroes, students, civilians, and even former villains are forced to cooperate if they hope to survive. Outside the safe zones, monsters roam endless corridors, forgotten civilizations hide unimaginable treasures, bizarre merchants appear without warning, and mysterious sponsors reward those who entertain the audience.

The Dungeon itself seems almost alive. It mocks, rewards, and punishes its Crawlers equally, constantly creating impossible challenges, absurd quests, terrifying boss fights, and moments of unexpected humor.

Whether you become a legendary hero, a feared villain, a ruthless lone survivor, or something entirely new is up to you.

One thing is certain.

The Dungeon is always watching.

And somewhere beyond the stars...

The audience is waiting for the next episode.
