He;s the big bro (oh nii saaan) of Miyuki Shiratori from Shutendoji He makes more appearences in the manga. In the anime he bites it in da fight against Jawanbokikai and his homies. I haven't read more of the manga. In the anime he's pretty bada55 though. If Miyuki and Jiro Shutendo breed I hope their kid gets Yusuke's coolness for Shuten Doji GX.
