The story starts with Danpei Tange, a frustrater fighter that quited the rings when he loses both things, his eyesight and his double-crossed disciple. Since them he lives a poorly life, begging and wasting most of the time. One day he arrives in a town which lives a violent, deceiving, Conny and lier young boy called Joe Yabuki, he picks fights most of the time as result of robbing, cheating and being dishonest but his incredible agility and power while brawling/fighting, captured Danpei attention with this natural talent that in a good use would make Joe a notorious and famous boxier, maybe a true champion one day.
