It has been five years since dungeons appeared in the world. These mysterious spaces are inaccessible to the police and military, granting entry only to individuals aged 15 or older who willingly choose to enter. Within them, one can level up, obtain fantasy items, and some individuals even become astonishingly beautiful.

Rokujo Yuta has been bullied since kindergarten. Consequently, instead of attending the Dungeon High School that everyone else goes to, on his 15th birthday, he decided to challenge a dungeon alone. This is the story of Yuta, who grows stronger than anyone else and becomes one of the 'Twelve Heroes' who move the world.
