A school student, Kotegawa Yui has had enough of the "ecchi" in the school, and tries to set the school right. Not only does she try to clean it up, but enforce some new school rules, and has a squad (so to speak), to check on the students. Shortly later, Yui has started to realize that Rito is behind all the "ecchi" in school. So she gives him punishment so he won't be able to talk to any girls for 2 weeks. However, she soon notices that there is still ecchi in the school, even with Rito out of the way. She then begins to wonder if she had interpreted Rito incorrectly. As Yui sees Rito leaving their school, she follows him, and realizes that he is a kindhearted person. She then removes his punishment. Meanwhile, Lala is throwing a party for Rito to cheer him up. She uses her machine to get him there, but as he is being pulled by the machine, he also accidentally brings Yui along with him. The next day, Rito accidentally knocks Peke off of LaLa causing her to lose her clothes. When Yui sees this, she gives Rito another punishment.
