Synopsis: Class Room

Chao, a young boy restricted to a wheelchair, eagerly awaits going to school to interact with children his age. Unfortunately, his excitement is short-lived as he enters his homeroom only to experience a surreal occurrence. As reality contorts, his classmates gradually discern that their instructor is, in fact, a concealed monster with the power to impose devastating penalties on those who cannot reply to his punctuation-based query. Will any pupil find the answer to the riddle before it is too late?
