She is a demon, but actually quite a young one. She used to be a very small demon, until Rui made her his mother in his Spider Family. They aren't related, and he punishes her when she fails. She has white hair, red dots on her face, white skin, and wears a long white robe. She cannot attack anyone up close, it's just not possible. She is terrified of Rui, so tries never to fail him. She, like everyone else in the family, protects Rui. She attacks by using dead or alive demon slayers as puppets.
