Boxer "Irish" Micky Ward's unlikely road to the world light welterweight title. His Rocky-like rise was shepherded by half-brother Dicky, a boxer-turned-trainer who rebounded in life after nearly being KO'd by drugs and crime.

The story begins with Takeru Yamato (Yatsurugi) lying on the ground, unconscious, struck down by a force that possesses a little girl. This witch and her four generals go to war against our heroes. A fight that seems unequal at first but the strength of their friendship will prove that nothing can beat them.
