After an initial failed attempt by Komari and Kudryavka to get Riki to follow them because of something seemingly terrible, Rin later texts Riki to come alone to her dorm room. Riki sneaks into the girls' dormitory at night, only to find Rin, Komari, Yuiko, Haruka, Kudryavka and Mio together for a sleepover. Surmising that Riki has been abducted after briefly calling him, Kyousuke plays games with Masato and Kengo to determine who will go rescue Riki. After eating pastries, the girls take turns bathing until Riki is last. However, he is reluctant to learn that his pajamas were replaced by a girl's school uniform to wear. A-Chan drops by to tell all of them to keep the noise down if they do not want a visit from the disciplinary committee. Unfortunately, the disciplinary committee ultimately arrives to warn them for being loud when they roll up some newspapers and start a sword fight. Kanata luckily does not recognize Riki while he is cross-dressing. The next morning, Riki leaves after thanking Yuiko for helping Rin socialize with the other girls. Riki runs into Kyousuke, who had just won the right to go rescue him after playing games the whole night.
