Ep. 15: Riki joins the girls' dorm sleepover and cross-dresses to avoid disciplinary committee detection.

15

Komari and Kudryavka fail to convince Riki to follow them, prompting Rin to text him to her room. Riki evades Kanata and the disciplinary committee to join the Little Busters girls for a sleepover. Kyousuke, Masato, and Kengo play games to decide who will rescue him. The girls bathe in turn, leaving Riki last, but he discovers his clothes replaced by a girl's uniform, which he reluctantly wears. The resident assistant warns them to keep noise down to avoid disciplinary committee visits. The group then hits each other with rolled newspapers, drawing a warning from Kanata, who fails to recognize Riki in his disguise. The next morning, Riki thanks Yuiko for helping Rin socialize and departs, encountering Kyousuke, who had won the right to rescue him after playing games all night.
