Rentt Faina has spent a decade tracking monsters, yet his skill often lags behind his ambition. He ekes out a meager living, hunting slimes and goblins for a handful of coins each day. His fortune shifts when he discovers an uncharted passage. At its end, he meets his demise in the maw of a legendary dragon. Yet he awakens as an undead bag of bones, determined to pursue Existential Evolution and rejoin the land of the living.
