Maid Latte & a Whole Bunch of Sweets
Erika asks Misaki for help when she accidentally promised a customer a date—which is against Maid Latte policy—should he win the all you can eat sweets eating contest at Maid Latte. Misaki decides to join the contest in disguise to try and win it. However, Hinata joins the contest and wins, and gets to choose a maid of his choice to serve and take a picture with him. Unfortunately, Satsuki forgets to remove the name “Misa” from the list, which Hinata naturally chooses. Satsuki and Erika then devise a plan to keep Misaki's secret with a disguise, but she, not wanting to lie in front of Hinata, decides to reveal to him that she works at Maid Latte. Hinata becomes a bit rowdy about this, to a point of risking her secret, but Usui, dressed as a butler, arrives and takes Misaki to the back and questions her change of plans. When Hinata later arrives, Usui warns his newly-recognized rival not to come near Misaki again. Misaki has no idea what's going on between them, though.

Maid-Sama!
Being the first female student council president isn't easy, especially when your school just transitioned from an all boys high school to a co-ed one. Aptly nicknamed "Demon President" by the boys for her strict disciplinary style, Misaki Ayuzawa is not afraid to use her mastery of Aikido techniques to cast judgment onto the hordes of misbehaving boys and defend the girls at Seika High School.
Yet even the perfect Ayuzawa has an embarrassing secret—she works part-time as a maid at a maid café to help her struggling family pay the bills. She has managed to keep her job hidden from her fellow students and maintained her flawless image as a stellar student until one day, Takumi Usui, the most popular boy in school, walks into the maid café. He could destroy her reputation with her secret... or he could twist the student council president around his little finger and use her secret as an opportunity to get closer to her.
