Konata and Yutaka catch a cold, and Yutaka's friends, Minami, Hiyori, and Patricia, come and visit her. They, Konata, and Yutaka discuss younger-sister-moe, Minami's lack of breasts and how Hiyori doesn't want Yutaka to read her doujin manga. After seeing a TV program about how xylitol chewing gum can eliminate cavities, Miyuki decides to test this out. As a result, one of her fillings comes out and she has to go to the dentist. Kagami and Misao play a video game together. Although Misao is terrible at playing them, she seems to be having more fun than Kagami who's playing to win. Patricia tells Kagami what music she's been listening to lately and how much she would like to have a maid. Miyuki tells her mother about her friends' opinions on Minami, but they seem to contradict with what Miyuki's mom recalls from Minami's previous actions.
