The Unwanted Undead Adventurer

Rentt Faina has spent the past decade hunting monsters, though he’s never been very good at it. He barely scrapes by, taking down weak slimes and goblins for meager pay. Then, by chance, he stumbles upon an unknown path. At its end, he meets a grim fate-devoured by a legendary dragon. Yet instead of dying, he awakens as a skeletal undead. Now, Rentt must pursue "Existential Evolution" in hopes of regaining his humanity and returning to the world of the living.
