Karen ni Musashi

Ichimonji Musashi is a very effeminate boy who is determined to live up the the manly name his father gave him, but on the day of this proclamation, he walks in on Ichinoki Chizuru, the manager of a maid café, while she's naked and falls in love. The only problem is Chizuru hates men! After Musashi is forced to work as a maid for her, she becomes "convinced" that if he can become a "girl among girls" she will accept his love. Just when Musashi vowed to be manlier!
