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. After having his friends trashed by Justice and himself beaten to a pulp by Pinko, Jimmy was surprised to find himself not wanting revenge. Seeing the apologetic state his leader was in, Zombie became fed up with him and decided to split from the group and fly solo. As he wandered away from the group, Zombie was reunited with a respected senpai who fought back against Justice to the bitter end. Reminded of his past, he makes up his mind…and revives the Germs to help him overthrow Pinko! But before he could accomplish his payback, Bara High’s strongest third year already had his own plans for Pinko. He decides to settle the score with him, lighting the fuse to one final brawl before their graduations!
