Akiko Himenokouji

Saint Liliana High School Second year student. Akiko is Akito's sister, and has a pretty appearance and polite manners. However, she has very serious brother-complex, and is taking a very active way to seduce Akito. She is also very proud of her brother complex and makes no effort of concealing it. She is the secretary of Saint Liliana High School Student Council, but is very reluctant when Akito interacts with other Student Council members.
