Gan's father, a hotdog supercop with the moniker of "Dan Goda," is fed up with this situation to the point where he decides to send Gan to his old educational institution: a fighting school called Roujuu Private High School. There, Gan learns to harness his raw abilities into "Gunfighting," the family martial arts style resembling firearms. Think .44 Magnum punches, Shotgun Fists, Sniper Stances, and you've got the essence of Gun-Fu down. At his new school Gan also falls madly in love hot chick, Yuki and runs afoul of 17-year old transfer student and sure-to-be-rival Garrick Rider, prodigal master of the Hanged Cross technique. Fights over Yuki's affections take place in the school stadium, but it turns that she has little need for defenders of her honor. Yuki is, like an overwhelming majority of students at Roujuu, a fantastic fighter. And from here on out, everbody is not only "kung-fu fighting," but also busy filling pages with over-the-top battle scenes. (Source: MU)
