Sayaka Kitaouji is the President of the Debutante Club, heiress of Makuhari Heavy Industries and the main antagonist of the series. Sayaka wants a Japan ruled by women as powerful as her to dominate the world. Most of the income for St. Ignacio's is funded by Makuhari Industries and because of this, Sayaka and the Debutante Club feel like they can get away with everything at school. However, Sayaka's plans to eliminate the Etiquette Club backfire on her as her mother funded the Etiqutte Club in order to teach Sayaka respect and courtesy towards others.
