Kiryuu Mizuha

Japanese name:

桐生 瑞葉

Keiki's younger sister. She's very close to her brother and frequently "flirts" with him as Keiki puts it, ranging from pampering him and seeking to have him pamper her to sneaking into bed with him claiming suspicion he'd finally awaken as a siscon. It is later revealed that she is the "Cinderella" who left her panties, and that she was adopted after the death of her parents and thus non-blood related, and has exhibitionist tendency, frequently strip naked in Keiki's room.
