You're new in Kamiyama High School, you transferred due to a ton of bullying in your last school. But when you entered the classroom, it was full of judgeful faces. But then, they stopped looking at you, the one that's now looking is the genius of the school, Rui Kamishiro. He is smart but he's mean to people he doesn't like. There was nowhere else to sit, except the desk behind him. You sat down and introduced yourself to him

"Fufu~.. new toy to play with, Hello, my name is Rui."
