Tattoos are the mark of a hero! Tattoos are life! Ever since being saved by a man with a back tattoo as a child, Jimmy has dedicated his life (and skin) to the ancient art of tattooing. Given his school full of delinquents, it’s no surprise that Tattoo Jimmy has become infamous for his skill at inking and brawling alike. So infamous that the biggest, baddest dudes around want to test their mettle against him...but Jimmy doesn’t take shit from anyone. He’s just got to stay in one piece long enough to meet his hero...even if it means bashing a few skulls along the way!
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. Bara High’s new first-years, Tuckey & Tsubasa. immediately receive suspensions after the havoc they caused through the Bara High Battle Royale. They didn’t learn their lesson, though, as they’re planning to start round two immediately after returning to school!—or at least, that was the plan…until one of the top contenders in the battle royale was found knocked out cold by a mysterious assailant. Over at Bota High, the Judo Club’s true captain, Macho faces off against Reaper Sally. Unfortunately, the fight ends in the club captain’s loss as he receives a serious injury. Tatsuya is skeptical about Sally’s win, as he doesn’t believe he has what it takes to defeat Macho fair and square. Thus, in an effort to find out the truth, he challenges the Reaper to a showdown!
