The chapter opens with a description of a "slippery" and "sensitive" beauty club that has been shut down because of the growing number of clubs in the school. The club's founder, a young woman named Ayumu, has heard that a similar club is going down, and has tried to convince the student council to reinstate the club. The girl, however, is very tight-lipped about the details of her club, so the club is shut down for good. The next exercise is to straighten the spine, and the group moves to a dark room to do the same exercise. The exercise is called "dark room fitness" and involves moving one's body to music without worrying about others watching. The group then moves to stretch the girl's shoulders.
