Bell Cranel wants to become the greatest adventurer in the land, but pursuing that ambition means entering the Dungeon: the monster-filled catacombs beneath Orario. Naive yet persistently optimistic, Bell gains support from the lonely goddess Hestia after a chance meeting brings them together.
Her help allows him to venture deep into the labyrinth, where deadly dangers surround him and a mysterious power stirs in the shadows. Returning to the surface offers no certainty, either. In Orario, gods and humans share daily life and work, but getting along is another matter, and survival takes effort even outside the Dungeon. Bell's pursuit of his dream brings mistakes and successes, along with new friendships.
