Nicknamed Momo-chan-senpai, she is disciplinary committee member of Otogi High School. She is a bisexual and will sometimes make suggestive passes at Ry�ko, whilst using her 'dumplings' to get assistance from naive boys. She is based on the titular character from the Japanese tale Momotar�, and is often accompanied by a trio of students whose names and appearances are based on the Monkey, Dog and Pheasant that accompany Momotaro on his journeys.
