Tokitou Kasumi♀

Kasumi is Kazuki’s older cousin and acts like his big sister. She is usually the school’s model student, but reveals a playful and spoiled side when around Kazuki. As Algester said before, she is very attractive to girls even to the point of giving love letters. She holds a close relationship to Gin but seems oblivious as to what possible implications could entail. Kasumi is currently the strongest dancer and regarded as the favorite to be the next Beltina.
