Once an all boys school, Seika High, a renowned school full of reckless and filthy students, has recently become a co-ed school. However, with the female population still remaining a minority even after the change over the recent years, Ayuzawa Misaki takes it into her own hands to reform the school and allow a chance for the girls to feel safer in the rough environment.Training, studying and even becoming the first female student council president of the school, Misaki has gained a reputation, among the male students body as an uptight boy-hating demon dictator and as a shining hope for the teachers and fellow female students. However, despite her tough-as-nails appearance, she secretly works part-time at a maid cafe in order to support her family. Unfortunately, her secret is soon revealed when the somewhat impassive Usui Takumi, a popular boy at school, nonchalantly discovers her in a maid uniform after school.
