The anime is adapting the Nozomanu Fushi no Boukensha light novel written by Yu Okano and illustrated by Jaian, currently serialized in the Overlap Novels imprint. J-Novel Club licensed the novel in English and describes the plot as:
Rentt Faina, a twenty-five-year-old adventurer, has been hacking away at monsters for a decade. However, without much talent for the job, Rentt finds himself stuck hunting Slimes and Goblins for meager amounts of coin every day. Little does he know, all this is about to change when he comes across a seemingly undiscovered path in the Labyrinth of the Moon’s Reflection. What awaits him at the end of the path, however, is neither treasure nor riches, but a legendary dragon that wastes no time swallowing him whole! Waking up a short time later, Rentt finds himself not quite dead, but not very alive either— He is nothing more than a pile of bones! Armed with nothing but his trusty sword, tool belt, and ghoulish new looks, Rentt sets off on his quest as a newly reborn Skeleton to achieve Existential Evolution, hoping to one day return to civilization with a more human form. Will Rentt succeed, or will the labyrinth consume him for the rest of his un-death…?
