Appearance: 160 cm, shoulder length hair and feminine body. Usually in school uniform or dojo ki or normal girly clothes with shirt and mini-skirt.

Occupation: Hayate's Assistant, High school student

More info: Hayate's younger sister. She grew up learning karate just like Hayate. Due to the huge age difference, she rarely sparred with her older brother but she is always looking forward to the opportunity. She feels both respect and a friendly rivalry as a fighter to her brother. She's now helping Hayate working as his assistant after school.
