Skeleton

Human bones reanimated through the infusion of the Mamono Lord’s power. They look like a kind of undead, but since their short-lived body was made through the infusion of mamano mana, 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. Just 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.
