Ah, his name is Ayame and he's a supporting character rather than a main character. His brother Yuki is one of the main characters but they're not very close because they're about 10 years apart. In the series, Ayame is trying to get closer to his little brother but Yuki thinks he's an idiot and dislikes his flamboyant ways. XD;

Ayame runs a costume shop which makes some rather unusual things (like wedding dresses for men!). And has a female assistant named Mine who dresses like a maid and loves to dress up cute girls in the outfits the shop makes.

hee I sort of wish I had a good place to put pockets in my D costumes without making spots lumpy or saggy. Seems like I'm always carrying around too much stuff when I cosplay. ^_^;
