Yuuki Nana

Nana is a meticulous and reliable honor student who serves as the class representative. She is good at both sport and study, and has a sharp mind; from the outside she seems like a perfect superhuman girl. However, because she is so serious, she can unconsciously become harsh when she sees sloppy or lazy people, which makes it hard for her to fit in.

On the other hand, when she puts on a maid uniform, her personality changes completely! She is transformed into a super adorable girl who is bubbly and affectionate. The transformation is so complete that she has become the overwhelmingly popular poster girl at the maid cafe where she secretly works as a part-timer.

She says she is under a "maid curse," but even she herself doesn't really know what that curse is.
