The Unwanted Undead Adventurer

Veteran adventurer Rentt Faina has spent years delving into labyrinths with little to show for it—until a fateful expedition ends when he stumbles upon a dragon’s lair and is killed. He awakens deep underground as a skeleton, the weakest rank among undead. Trapped in the maze, Rentt battles its monsters and realizes that defeating them grants him the means to evolve into higher undead forms, even ones that can regain flesh. Clinging to that possibility, he sets his sights on continual evolution, hoping one day to reach the near-human pinnacle: a vampire.

Returning to the surface comes with a new danger: being hunted as the very creature the guild would purge. With an unremovable mask concealing what he has become, Rentt is taken in by Lorraine Vivier, a brilliant researcher and retired adventurer, and begins again under her surname as a novice. Still chasing the childhood dream of becoming a mithril-class adventurer, he must navigate guild life carefully—because a single revelation could turn his second chance into a death sentence.
