A second-year student at Seiran Academy High School. A short-distance runner on the track team. Because of her boyish looks and the fact that she is the team's fastest runner (although not as fast as Kurosawa), there are quite a few students who look up to her. However, because of her naturally timid personality, she disliked the inflated image people have of her. She is Shiramine Ayaka's cousin and childhood friend, and is an older sister figure to Shiramine.
