- Like Chisato and Yukari, Hisae Aoki (青木 久恵 Aoki Hisae) is one of Miyu's classmates in the TV series. A shy girl, Hisae is one of the top students at the school, as well as being a bit bookish. So it was a bit of a shock to the entire school that she had been murdered horribly near the end of the series, the killer being Chisato, who was secretly a shinma hunting for Miyu.
