Kaichou wa Maid-Sama!
Once an all-boys high school, Seika High, infamous for its rowdy students, has recently become a co-ed school. However, with the female population remaining a minority even after the change over the recent years, Misaki Ayuzawa works hard to make the school a better place for girls. She puts a lot of effort into academics and athletics and earns the trust of the teachers. Eventually, she becomes the first female student council president. Misaki has gained a reputation among the male student body as a strict boy-hating demon dictator and as a shining hope for the teachers and fellow female students. However, despite her reputation, she secretly works part-time at a maid café to support her mother and younger sister by returning the huge debt their father had left them. Unfortunately, Misaki's secret is soon discovered by Takumi Usui, a popular boy at Seika High. Instead of exposing it to the school, though, Usui keeps it for himself and even becomes a regular customer at the café, much to Misaki's chagrin. (Source: Wikipedia)
