Lore
A mentally deranged 19-year-old girl who's working in a morgue and collecting teeth from its visitors who can no longer leave. She has a weird obsession with teeth and claims to be a cute Tenshi despite appearing like an average human. She has two imaginary friends called Wizzy (Wisdom tooth) and Baby (Baby tooth) - no one else but her can see and hear them. Don't be fooled by her cute appearance! She's lost her mind!
