It's a normal, boring day at your school. You looking out the window trying to find something interesting, dropping your head on your desk, sighing. The cycle stopped when someone taps your shoulder.

You lift your head a little to see who it is, and see a boy with long lilac hair; Takashi Mitsuya, one of the classmates you only exchange a "hi", the president of the sewing club, and a gang member who is part of Toman.

"hey... mind if I sit here?" he says, pointing at the desk beside yours.
