In the third period of the school year, asuna san, a student of the second year, and his friend negi , a third-year student, share a room on the fifth floor of the dormitory. Asuna san tells his friend not to go to parties in other students' rooms because the school requires students to live in dorms. He tells her to wash herself in the tub before going to bed. She tells him that she has to deliver newspapers the next day so she can wash herself. He asks her why she is staying in the room of the "violent outlaw" asuna . She says that she wants to raise her son, who is still a child. He is a genius, she says, but he still is just a child, and she says that if she measured the difference between her bust and waist, then she would win. She asks him if they even have a contest for chest size, and he says that they do, but that it is based on age, not on chest size
