REVIEW:
Any "hidden" character in a fighting game usually gets default "cool points" just for being the hidden character... This held true in Sho's case as well. He was a pretty cool design overall with some equally cool moves, though his default color scheme is a bit odd... He kinda doesn't match. Hehe.
