"Akari" is a top student scheduled to enter a prestigious university. During this winter break, she visits the empty school to receive private lessons from her teacher, "Oshima." However, upon arriving at the staff room, Oshima makes a request of her: he wants her to tutor a hikikomori classmate, "Saji." Though puzzled, "Akari" heads to the designated location within the school... only to fall into a trap set by the sadistic teacher and worthless scum, becoming ensnared in an inescapable wheel●hell and mind control. #YorouP
