Skeleton

Skeletons are undead-type monstergirls that are created using necromatic spells, presumably by liches. Oddly enough, their closest relative is probably the golem, as skeletons technically constitute 'bone golems'. Along with the alp, they are one of the only monstergirls that arise from former males.

Human bones reanimated through the infusion of the Demon Lord’s power. They look like a kind of undead, but since their body was made through an infusion of magical energy, and they are very short-lived, they are a kind of golem, made using bone as the material. Or it could be a type of ghost dwelling in the bones. That’s another possible explanation. The opinions of researchers are split. In the same way as other undead, they retain memories and thoughts from when they were still among the living, but most of them have weak thoughts and a fuzzy sense of self.



When they get hungry instinct pushes them to wander in search of the spirit energy needed to maintain their body. If they see a man, they attack and take in spirit energy through intercourse. Perhaps due to being ephemeral bone constructs, they don’t have much strength. A strong force can shatter their body, but they always come back together. Once they give chase, they tend to follow you everywhere, so it’s very troublesome. But, once their hunger for spirit has been sated, they become docile, perhaps because their thinking ability is weak. They entrust themselves to men they like, and even begin following their orders.

Zombies and other undead type monsters can fundamentally never rise from a man’s corpse; however, in the skeleton’s case, magical energy doesn’t dwell within the body, the body itself is made up of magical energy. They are an exception, and men’s bones can become monsters too. Even then the body is still female. Thoughts and memories from their lives as men remain, but they mostly become twisted. “When I was alive I was a woman.” “When I was alive, my best friend was my lover.”

A class of spells used for manipulating the dead exists known as “necromancy” but if used near a powerful demon, in a dungeon filled with magical energy, or in the demon realm, it is very dangerous. Upon raising a skeleton, it would be infused with magical energy and become a monster. Being newly born, she will be very hungry and likely attack at once.
