[[Curses]] used on corpses/Undead.
In a way, [[Cotton]] is considered Zonbi
At the Current era, where Otòn is a corpse roaming the oceans, the shadows are able to take over remains of people/animals to gain a bit more power and stability; but can only be in the general shape of those remains. These are called Zonbi. They gain the vague behavior of whatever corpse they picked up, but weaker; a zonbi cat will just act like a weird creepy cat, and a humanoid zonbi will act like a weird creepy kid. The bigger the corpse, the more unstable however..! So zonbi of adult humans will likely just act like zombies. They do not have a beating heart, so what they pick up is only natural body instinct.
Zonbi are still very often, but not always linked to Otòn like shadows are, and they are much more stable, individualistic, and strong than typical undead. They frequent both land and sea.
Zonbi may attack humans, but will attack undead first.
