Kaichou wa Maid-Sama! (literally, The Class President is a Maid!) is exactly what it says on the tin: By day, the heroine Misaki is the tough-as-nails president of her school's student council, to whom all the male students must bow down. But after school, she's a mild-mannered cosplaying waitress in a maid cafe, who must who cater to her male customers' every whim.
Obviously, a strict framework of gender identity is very potent in this series... while at the same time there are ventures by many different characters to cross those lines, the acceptable limits of which are constantly tested. One of Misaki's classmates, Aoi Hyodo, embodies this test perfectly.
