Chizuru Komai

Age: 16

A classmate of Momoko, she is a very bold and stubborn girl who has trouble expressing herself. She does not compromise well with others and tends to be rather single-minded which makes her difficult to deal with. She is deeply in love with her older sister Shigure and tries desperately to make her see it. She goes to Momoko for advice and succeeds in achieving her older sister's affections, which leaves Momoko distraught in learning that she assisted an "unnatural love." She is a member of the school's drama research club to which she is very dedicated.
