The petite female assistant of Gunpei and the Oujou White Knights has gained recognition for her dedication to recording football games and collecting thrown garbage with a trash bin. She has formed close bonds with fellow members Takami, Deimons Mamori, and Suzuna. Despite initially taking on this role as a means of avoiding work from her parents who own a grocery store, she persevered and became an excellent manager for the Oujou White Knights.
