The main character, Banbangi, is strong in Kenpo but weak in Famicom. His good friend Hikaru-chan is a big fan of Huamicom. The two were competing in the Famicom game, but Ban, who could not beat Hikaru-chan, got disillusioned and used Kenpo towards the controller during the game. By synchronizing the electron wavelength, Ban entered the world of the game. Ban desperately fights against enemy characters one after another with martial arts. At that moment, the Famicom Champion Denpei Tsurugi appears, and although he somehow manages to save the savages with his special moves, even Denpei can't help himself, but a more terrifying enemy character appears!
