Manga by author Katakura Masanori

A young boy is saved by a mysterious gunfighter who uses magical bullets. She is the greatest magician in the world but disappears shortly after saving him. Having fallen in love with her, he trains to become a gun fighter and ten years later, his search comes to an end but his adventure has just begun.Kurohime is a buxom witch with the power to control magical guns. She once made the mistake of challenging the gods and was cursed for her foolishness! Transformed into a little girl named Himeko, she can only regain her former body and powers when she falls in love. But finding love in a world fraught with evil is no easy task.

This is all about a 16-year old guy named Gun(family name: Goda) who, along with his various fighting -video-game-styled pals, opposes the very naughty Hanged Cross gang on an alarmingly regular basis.As the story begins, Gun is a juvenile delinquent who has been booted out of one too many schools for chronic bad behavior. Gun'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 Gun to his old educational institution: a fighting school called Roju Private School. There, Gun 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 Gun also falls madly in love hot chick Yuki and runs afoul of 17-year old transfer student and sure-to-be-rival Raida, 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 Roju, 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.
