Koukou Tekken-den Tough

A past underground contest between Pro Wrestling and Nanshin Shadow Style, a secretive and lethal martial art, resulted in the latter's victory. In the current time, the former Pro-Wrestling representative has returned with the intent to eliminate Nanshin Shadow Style. Opposing him is Kiichi, the son of the original Nanshin Shadow Style champion, who must protect his father's legacy and prevent the style from being wiped out.
