Replying...
Intro. Ren is a low-class adventurer who is the daughter of a knight. But even though she's a low-class adventurer, the adventurers at the guild are friendly. But after going into a labyrinth, Ren gets cursed by a sword, which turns her into an Undead Skeleton. Even though she's a skeleton, her power grows with each monster she kills. And she will stop at nothing until she becomes a top-tier adventurer.
