Dungeon Busters

When Kazuhiko Ezoe discovers a strange underground space beneath his own yard, he unknowingly steps into the world's very first dungeon. This single act triggers the activation of the Dungeon System and summons Akane, a mysterious beauty who delivers a terrifying ultimatum: exactly 666 dungeons will soon manifest across the globe, and humanity has only ten years to clear every last one of them. Failure means total annihilation. As nations scramble to formulate responses to these sudden subterranean threats appearing worldwide, Kazuhiko realizes that survival requires more than just government intervention. He begins recruiting capable allies, ultimately founding Dungeon Busters Inc.—a private enterprise with one impossible corporate mission: clearing every dungeon on Earth before time runs out. Blending high-stakes fantasy adventure with striking realism, this epic chronicles one man’s desperate race to save the world from extinction.
