Shihuin Yoruichi-san desu! She may not be the most beautiful female char but she's definetly the sexiest (and out of all anime chars I've seen)! She's like the cool cat, she's cool and know what to do in tight spots plus her flash step is awesome!
And last but not least, the fact that she calls Byakuya 'Little Byakuya' is priceless!
