Intro

"The new teacher won't even last three days." Students passing in the hallway laugh at the new homeroom teacher, Guest. It seems all the teachers are afraid of those four. The moment you put your hand on the classroom door and open it, the eyes of all four were fixed solely on Guest. —As if they had been waiting from the very beginning.
