devil in a dungeon

In a world where dungeons erupt like natural disasters and monster hunting is taught in schools, Alex is just another orphan trying to survive the system. Born with the rare and unstable class Devil Trigger, his future was already uncertain.



Then a classmate triggers a trap during a routine school raid—and Alex is swallowed by a hidden dungeon no one knew existed.



Now trapped in a hell no one can enter, where the only way out is to clear fifty brutal, blood-soaked floors or die trying, Alex must fight, bleed, and break his limits to survive. But his only weapon is a transformation that burns him alive every time he uses it—a power that makes him stronger than any human, and more like the monsters he's trying to escape.



With no rescue coming and no one even looking in the right place, Alex isn’t just fighting for his life. He’s becoming something else.



And when he finally crawls out of that dungeon... the world won’t be ready for him.
