一文字 さやか

A girl in the same class as Yamato. Kanban musume for the cafe "Ichimonji", she helps with the store after school. Fed up with Yamato always overstaying on 1 cup of coffee and complaining that the coffee is bitter. Capable of strong-willed quick wit.
Actually she's another character from the manga Dengeki Stryker and his real father is Ichimonji Souichirou(Stryker Ten)
