Cece Wolf is Charlie's younger sister. Like her brother, she's a total psychopath. Despite her appearance, Cece is only five year old. At the age of five, she was hit by a speeding car, and died. Charlie's telepathy absorbed Cece's psyche as she died, permanently bonding her mind to his. Her appearance is based on how Charlie imagines she'd look, because she's just a psychic projection. Although Cece is just a ghost, she often possess Charlie's body causing him to appear to have a split personality. She can also take control of Charlie's telepathy to attack opponents.
