As the summer break is under way, Nyamo attempts to make Yukari set herself a schedule, splitting her time among rest, leisure, and swimming. Meanwhile, Tomo, Yomi, and Osaka are invited to go to Chiyo's house. They are overwhelmed by the spaciousness and the splendour of the mansion. They are even more surprised when Chiyo invites them to her summer house, bringing Sakaki, Yukari, and Nyamo along as well. While Chiyo, Tomo, and Yomi play in the ocean, Osaka and Sakaki sit together with the former spouting trivial facts. Tomo and Osaka try to make the night more exciting with scary stories and dirty talks, though both fail to do a good job. Afterwards, everyone goes outside to play with fireworks. Upon returning to school, the girls share their pictures taken at the summer house, though strange reactions occur when viewing them. (Source: Wikipedia)
