She is the only daughter of the owner of the world-renowned snack food manufacturer, Kamishiro-dou. Her grades are always at the top of her class. She's a decent athlete, and even competed in national tennis tournaments during her junior high school days. She is strong-willed and quite prideful, but respects Maimi and Miu's seniority. She speaks her mind and so is constantly arguing with the equally strong-willed Kensuke. She always travels by car with her driver, the elusive Hattori, always at her side.
