Buntaro Kuno made his first appearance in Power Instinct: Matrimelee. Buntaro is a conflictual schoolboy who has his own gang, who cheers him on in his fights. He also is the older brother of Shintaro and in contrast to his style, fights mainly with kicks and various dive attacks. Although Buntaro likes to pretend to be a tough guy, he is really a very emotional and tends to cry every time he feels moved, especially when he is watching a sad scene in any anime. His looks are inspired by the yankee boom that was popular in Japan between the 1970s and 1980s which style consist in wearing sunglasses and dyed blonde hair.
