Skip!.The students of Kaimei High are going on a class trip, but first, they have to participate in a rope skipping competition to see which class gets the best rooms. Saaya doesn't have an athletic bone in her body, so is worried she's going to doom her class to the worst rooms of all, until the Sket-dan tries teaching her how to skip! After, Tsubaki's class has to sit with Bossun's bus for there were only 7 buses and 8 classes. On a 20 minutes break, Switch suggests to Saaya to ask Bossun directly how he feels towards Himeko. However, there's a problem. Due to Chuuma's drug, Bossun and Himeko's souls are switched! Not only that, Tsubaki is also hypnotized!
