Voodoo Doll (HOA Halloween One-Shot)

[Fabian and Nina are possessed by a sadistic, demonic, magical duo. They take all of the students of Amun Academy and lock them up in cages to torture them to death all with only a voodoo doll. It's up to only Joy to escape, whether it's with or without the others.] Rated M for gore and violence. Reader's discretion is advised.
