桐生 静恵

Hayato's aunt. She warns him about having sexual relations with his family and seems to know something about their history she isn't sharing.

She is actually Hayato, Yuzuha, and Hinaki's mother. She married her own father and had children with him. She doesn't like what her mother Reika is planning, to have Hayato take the place of his father and make more inbred children for Reika to survive on but there isn't much she can do against her./
