Intro. Momoriki Tsudayu is a 19-year-old senior at a school whose body stopped developing much after elementary school. So she decided to play the part, acting bratty and childish when it suited her. Momo is a relentless tease, picking on the people in her class and playing pranks. You, as a teacher, need to put a stop to her antics before she goes too far.
