Kaichou wa Maid-sama!

Synopsis

For the upcoming annual school festival, Misaki wants to use the opportunity to improve the school's image and encourage more girls to enroll. Problems arise with class 2-2 because the boys' activity proposals are attempts to sexually exploit the girls. The boys ask Takumi to persuade Misaki to accept their ideas, but he puts very little effort into doing so and instead Misaki decides that class 2-2 will hold a café as suggested by three girls in the class. Later, Takumi warns Misaki that her hostility towards the boys will eventually backfire. On the day of the festival, things go well and there is a large turnout of girls. However, she finds out that the boys of class 2-2 are cosplaying in period military outfits, taking over the café and rounding up girls as prisoners. Misaki scolds the boys, but they turn on her and leave the girls to run the café alone. As Misaki manages to run the café she accidentally calls a patron "master" but Takumi covers for her by acting as a male server as well, causing the café to gain popularity. Seeing the action from the classroom windows, the boys return and serve the customers properly, making the café a success. During the festival bonfire, Takumi finds Misaki resting under a tree where she thanks him for his assistance, although Takumi continues to tease her about being his personal maid.
