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, having set his sights on Jimmy and his friends, assigns Husky, a first-year student at Manji Botan High School, to destroy them. His backup? Two of Jimmy's friends from Bara High's technical track, the Dreadlock Brothers, Tohru and Hiroshi. Although it is to protect their cherished team, Tohru and Hiroshi are still finding it difficult to betray Jimmy. In their impasse, a certain man appears before them and tells them something that would give them a push in the right direction.
