Weak spot: Armpits
Fetish: Harsh criticism

The principal of the high school the main characters attend. She is the wife of the previous principal who passed away, and Hakua's older sister as well. Very friendly but also relentless and quite hysterical at times as well. Ajisai feels sad over the fact that her relationship with Hakua became completely estranged after she left the house to get married with the ex-principal. Because Ajisai hasn't had sex for a long time, she is quite frustrated, but feels satisfied trying to seduce Kou over.
