Aiko's older sister and the current student council president. Unlike what her sister thinks, Midori hates doing everything perfectly, and has quite a refreshing personality, which has made her popular with younger girls. Since Midori has no idea of her sister's resentment towards her, she has a hard time showing her sisterly love towards her. In fact, she admires Akane for being extremely open about her love towards Kou, and wishes to be able to do the same.
