Jimmy (A.K.A. Katsuya Onishi) is a first year at Bara Cross High School's technical track. When he was young, he was saved by a legendary tattoo artist known as "Katsushin." Ever since then, he's become captivated by the art of tattooing, even going as far as to tattoo his body all by himself! His dream is to move to America and pursue his savior in order to study from under him and become the world's number one tattoo artist. Pinko has had enough of Jimmy and decides to mount an operation that will crush his gang once and for all. He sends four of his best men to take out one of Jimmy's key members each, in an attempt to wipe them off the map. Pinko informs Jimmy that only the winners of each duel will be allowed to reconvene with them in a final battle between the two gangs. Nevertheless, Jimmy is confident that each and every one of his friends will make it through, and readily awaits their arrival with Pinko. However, Justice's elite members aren't to be trifled with. Will Jimmy and his friends be able to emerge victorious against the number one gang in town?
