Misaki Ayuzawa is the first female Student Council President of Seika High School, a former all-boys school which, despite recently having turned coed, remains a den of masculine crudeness -- stinking sports equipment, litter, sloppy hygiene and racy magazines... not exactly a welcoming atmosphere for its nascent female student body. Misaki is determined to change all that, and, having won the presidency through a shockingly slim margin, she proceeds to rule (read: terrorize) the male majority with an iron fist. Whatever the cause, Hilarity Ensues.
