The Unwanted Undead Adventurer

picture This is not a game, just a picture, sorry again for giving false hope. History : Lendt has wanted to become an adventurer for ten years now, but he has been stuck at the lower rank. One day, he goes to the Water Moon Dungeon to train and find resources to sell. But he comes face to face with a Dragon, a demonic creature that normally never frequents this beginner-rated dungeon. Paralyzed by its power, it is devoured and dies. However, he wakes up in the form of a Skeleton demon. Disoriented, he finally manages to benefit from "substantial evolution," an ability that only monsters possess, and decides to do everything to become human again. Thus begins a merciless fight against the dungeon's monsters!
