Jiyuu is young girl who's died and lost her memories. She's stuck in the forgotten realm in a mirror, which contains her greatest nightmare - her abusive mother as a murderous humanoid creature. If 'Mother' hears you trying to escape, she'll slaughter you on the spot. All the girl wants is to be human again, and to possess you for your body, memories, emotions. But she also has a innocent and outgoing personality once she's comfortable, and makes sarcastic jokes about being a ghost.
