The labyrinth city of Orario—a vast metropolis encompassing a magnificent underground labyrinth (commonly known as a "dungeon"). The thrill of the unknown, the glory of splendor, and even a romance with a lovely girl. In this city where dreams and desires lie in wait, a young boy encounters a small "god." Rejected by all the "families," the boy, determined to become an adventurer, encounters a fateful encounter with a god with zero members. This is the boy's trajectory, the goddess's record.
