Roughly thirty years have passed since "Dungeons" suddenly appeared in the modern world, and "Seekers"—individuals suited to Dungeons—simultaneously began to emerge among people.

Musou Daichi, a high school graduate, single part-time worker, wakes up one morning to find he has become a "Seeker." "Seekers" are individuals with unique abilities, possessing levels, stats, skills, and more.

Daichi heads to a nearby Dungeon on his bicycle and explores his first Dungeon through trial and error. This is the story of a young man who gradually gains power, raising his level, acquiring skills, and exchanging magic stones obtained from defeated monsters for cash.

※From a certain point, the story effectively becomes an isekai fantasy.
