The Unwanted Undead Adventurer - Tome 01

Lendt has wanted to become an adventurer for ten years now, but he has stagnated at the lower end of the scale. 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 dungeon classified as "beginner". Paralyzed by his power, he gets devoured and dies. However, he wakes up as a Skeleton Demon.
Disoriented, he finally succeeds in benefiting from substantial evolution, a capacity that only monsters possess, and decides to do everything to become human again. Then begins a merciless struggle against the monsters in the dungeon!
