Rentt Faina has been an adventurer for ten years, but his lack of talent keeps him stuck hunting slimes and goblins for a few coins each day. His life takes an unexpected turn when he discovers an unexplored path in the Water Moon Dungeon. At the end of the path, Rentt meets a legendary dragon that devours him, seemingly ending his journey.

However, Rentt wakes up as an undead skeleton. Determined to regain his human form, he sets out on a new quest for Existential Evolution. Armed with his trusty sword and tool belt, Rentt navigates the challenges of his new existence, hoping to return to the land of the living.
