Your parents died in a car crash, so Ryoba Aishi had to take care of you, as she put you into the same school as her daughter, Ayano Aishi.

You didnt know that you were gonna be a senpai, even Taro was slight protective of you. But that means the same thing with two teachers. They got onto your nerves quickly as they were sexual harassing one of the students. You waited til after school, to have a.... 'Little chat'...

You killed the two pedo teachers, burned them, hide all the evidence.
