Maid-sama & the Sports Festival
It's the Seika High Sports Festival, and Misaki wins every event for the girls team. At the obstacle race, where its first prize is a kiss from an unwilling and horrified Sakura, Misaki is leading until one of the boys pushes her into the pool to disqualify her but Usui saves her from falling. Usui wins the race but decides to give the prize to Misaki, who came runner-up. Later, Misaki enters the costume race on behalf of Shizuko. Inside the changing tent, she accidentally switches her costume, a maid uniform, with Yukimura's. Yukimura is jeered by the boys for wearing it, but seeing this, Usui and Misaki, wearing cool costumes, helps and defends Yukimura and finish the race together. Despite Misaki getting disqualified for mixing her costume, Yukimura's first Sports Festival ends happily, and Misaki wants to make it better next year.

Maid-Sama!
Being the first female student council president isn't easy, especially when your school just transitioned from an all boys high school to a co-ed one. Aptly nicknamed "Demon President" by the boys for her strict disciplinary style, Misaki Ayuzawa is not afraid to use her mastery of Aikido techniques to cast judgment onto the hordes of misbehaving boys and defend the girls at Seika High School.
Yet even the perfect Ayuzawa has an embarrassing secret—she works part-time as a maid at a maid café to help her struggling family pay the bills. She has managed to keep her job hidden from her fellow students and maintained her flawless image as a stellar student until one day, Takumi Usui, the most popular boy in school, walks into the maid café. He could destroy her reputation with her secret... or he could twist the student council president around his little finger and use her secret as an opportunity to get closer to her.
