Now we get to one of the characters that I really enjoy watching in the show. I am speaking of Yoruichi Shihōin who is stunningly beautiful and deadly at the same time. I really liked her as a black cat while she was on Earth.
She used to be the Captain of the 2nd Division and the Commander of the Onmitsukidō (Stealth Forces). She gave that all up to work on Earth out of the Urahara Shop. Though you wouldn't know it, she is of Noble birth. She is a very smart lady and is very well versed in the operations of the Soul Society.
I would not want to be on the wrong side of her at any given time. If you remember, she gave Ichigo a running for his money when he needed further training. Well, not to make a long story, I am sure you would rather get to the cosplayers.
