Yoruichi Shihoin, the cat that can speak and the ninja that can defeat other shadows. Yoruichi is awesome, whenever she first got introduced, she was known to as nothing but a cat, she helped both Urahara and Ichigo throughout his process to master his Inner Hollow. Her ninja abilities are also to speak off as it greatly reflects within his awesome fan art.
This magnificent fan art of Yoruichi was done by hollyoakhill who has a number of some fantastic looking anime art, if you like what you saw here, be sure to check her out. This artwork was actually done in around 2 to 3 hours, which to me shows how greatly talented she is. Also be sure to share this work with some other fans.
