Pool Cleaning! Pool Racing! Pool Warring!.When it looks as if Yakumo will be forced to clean the school swimming pool, Hanai steps in and declares that his class will do it instead. A brief soap fight between Hanai and Harima (because of a misunderstanding from the latter when he hears the former speaking of "Tsukamoto-kun", not noticing he is talking about Yakumo, and not Tenma) quickly turns into a pool hockey match, with the winning team deciding what the class will do for the next school festival; a food stand or play. Hanai is firmly on the side of the play, hoping he'll have a chance to play a prince opposite Yakumo's Sleeping Beauty. Meanwhile, the non-participants become bookmakers, cheerleaders and commentators, while Fuyuki snaps revealing shots of all the female players (much to Harima's anger and Hanai's annoyance) and one lone student, Karen Ichijou, diligently tries to clean the pool. Trying to turn the water back on, Karen is startled and accidentally breaks the tap, soaking everyone.
