Kotone Kirishima is the twin sister of Akari and the older of the two. She, along with her sister, are the daughters of the Buddhist monk in the temple. Despite her gentle and sweet outward demeanor, she is interested in Junpei mainly because of his misfortunes, and can be considered sadistic, delusional, and an obsessive stalker. In the anime, she is shown to have this sort of behaviour even at a young age towards a teacher. She also shows jealousy if another girl gets too close to Junpei. She is aware of Kaede's feelings for Junpei.
