A friend and fellow club member of Haruhiko and Mai. She has the ability to seal Phantoms by eating them. She has a very large appetite, but rarely has money for food. She practices Aikido and is always throwing Haruhiko when she gets embarrassed.

Her parents are very strict and do not like her using her ability and tell her to stay away from Phantoms. She adores Mai because she reminds her older sister who liked to ride bikes, but her parent's disapproval of her hobby drove her away from home...
