Nutcracker is a living male doll and a serial killer. He only killed female victims because he thought women were as beautiful as flowers. When his victims died, he would decorate the corpses of his victims with flowers as art in glass coffins that he made, and he would make dolls resembling his victims to be placed next to the corpses as a challenge to the detectives and police who were unable to catch him. He likes to sing the song "London Bridge is falling down" very much.
