鞍馬 阿澄

A mysterious transfer student all the way from Kyushu. She introduces herself to her new classmates by saying she'll have sex with the twenty males in the class up to high school graduation. Real name Hiiragi Tsubaki (柊 椿姫), she began dating one of her classmates in the school she transferred to one year before the game's events. The dominant girl of the class (parents were members of the school executive committee) wanted the boyfriend for herself, so she forced the issue by asking two of the class playboys to repeatedly rape Tsubaki and then frame it up to make it look like Tsubaki was responsible for being a slut. The boyfriend took the bait and dumped Tsubaki, who was then bullied to the extent she tried to commit suicide. Tsubaki survived jumping from her school roof and was saved by her tormentors. The school covered up the incident and made it look like she never existed. Tsubaki is shipped out to a mental hospital to recover from the psychological trauma she endured, which was so severe she developed multiple unstable personalities to cope. One year later she recovers enough and returns to the same school she was bullied in as "Kurama Azumi", now with the goal to earn her revenge against the classmates responsible for her torment and the school board who were accessories to the deed. As she was an orphan and her experience had changed her appearance and personality, she was no longer recognisable as their former classmate. In the end, Azumi succeeds in getting her entire classroom expelled from school, suspended or in long-term absence from class. To top it off the school board agrees to turn a blind eye to any and all actions she commits that would otherwise get her expelled. No one bar her current/former homeroom teacher realises who she was at the end, and even he can't do anything about it as she has a handle over him. Although revenge served cold turned out to be hollow, she earned the right to live again having removed her former tormentors. It is uncertain to what extent her personality reverted to "Tsubaki".
