Every July the all of the first grade classes are sent on an outdoor learning trip. Mr. Ryukasaki has decided on a location, since nobody in the class seemed to have a preference. They don't want to admit that they have any interest in this learning trip. You see, this learning trip has nothing to do with school work. It's purpose is to break the students out of their shells, students who only care about their grades and nothing else. All of the students think this way, it's just the nature of attending an elite school. When they arrive at their destination they're surprised to find out that it's a nudist campsite!
