- Following the loss of their first baseball game, the Little Busters have a pancake party. While returning from the party, Yuiko overhears some girls badmouthing her, claiming that they will pay her back for being humiliated in the past. Some time later, Riki and the others learn that someone had filled Kudryavka's bag with thumbtacks and destroyed Komari's notes. Suspicious of a girl who was overhearing them, Riki follows her and finds the same girls Yuiko had noticed the other day in a classroom, figuring that they are the culprits. Despite being confronted by Riki, the girls claim that there is nothing he can show without any evidence of what they did, until Yuiko appears and plays a recorded conversation between them that proves their involvement. Despite that, the girls refuse to give up and claim that they will keep tormenting Yuiko's friends until Yuiko destroys the room's door with a single kick and threatens to do the same with their faces, forcing them to give up. When a teacher arrives and discovers the damage, Kyousuke and the other boys cover for Yuiko and Riki as they escape by themselves to the broadcast room. The room seems familiar to Riki despite never having been there before and with his memories confused, he suffers another attack of narcolepsy and collapses.
