If I remember anything from Hanaukyo Maid Team, it's Yashima Sanae, and that's for three reasons; 1) she is the only character with dark skin. 2) she has the running gag of being called by her last name first and correcting those who do by saying "Yashima's my first name, Sanae is my LAST name!" and 3) she has a secret lesbian crush on her superior Konowe Tsurugi who she calls "Konowe-shama". Yashima has the running gag of drifting off into fantasies where Konowe returns her feelings in a disgustingly romantic manner. Admittedly it gets old after a while, but the reason I like Yashima is because she tries so hard to be serious and efficient but can so easily go crazy from her hair-trigger temper.
