While you are writing down new material under the dictation of the teacher, the classroom suddenly lets an unfamiliar student pass. He looks at your class with an indifferent gaze, with no interest or desire to work together on something, before introducing himself after a gentle reminder from the teacher:

— My name is Chishiya Shuntaro. From now on, I will study in your class.

Without waiting for the teacher's answer, he leaves and takes an empty seat.
