Dungeon Busters

When Kazuhiko Ezoe discovers a strange underground space hidden beneath his own yard, he unknowingly steps into the world’s very first dungeon. This discovery triggers the activation of the Dungeon System, summoning a mysterious woman named Akane who delivers a terrifying ultimatum: six hundred and sixty-six dungeons will soon manifest across the globe, and humanity has exactly ten years to clear every single one. If they fail, the only outcome is total annihilation. As governments worldwide scramble to respond to the sudden emergence of these deadly labyrinths, Ezoe refuses to leave the fate of the planet to chance. He begins recruiting capable allies, ultimately founding Dungeon Busters Inc., a specialized organization with one unprecedented corporate mission—conquering every dungeon on Earth before time runs out. Blending high-stakes survival fantasy with striking realism, this epic chronicles one man's desperate race to save the world from impending doom.
