Unchain plot
Once upon a time there was a boxer named Unchain Kaji. As a boxer he was not much, because he never won. After retiring from professional boxing, he started his own business in the village of Kamagasaki. In addition, he also made himself available as a private detective and occasionally tracked down a missing pet. But his business did not go well. Due to his drinking problem and after-effects of boxing injuries, his behavior begins to take on extremes. When one day one of his employees threatens him about his salary, Kaji freaks out. He pours a tub of yellow paint over himself and armed with a hammer and wrench sets out to raid Kamagasaki's job center...
