The daughter of Rosa Ushiromiya, her father is unknown. Her childish behavior often frustrates her mother. She has no concern whatsoever for studies or friends; however, she shows a strong interest for the occult, black magic and such and memorizes as many inconsistent bits and pieces of information with her natural gift of memorization. A little apprentice magician who inherited the black blood from Kinzo, despite her youth, she possesses a natural talent that Kinzo lacked. Her powers may be weak, but her enchanting ability to give magical power to tools is a natural gift, and the magical items she makes are a match even for the master class.
