Mugen's highly unorthodox swordplay and a fighting style based on breaking – dubbed "champuru kendo" (Champloo Kendo in English) and ostensibly developed by himself – taking bits and pieces from all forms of martial arts and making up the rest on-the-go as he fights his opponents, make him a force to be reckoned with. But despite the unpredictable nature of the fighting, it was pointed out in Episode 25, that his improvisational style, exposes his limits easily, giving experienced fighters the knowledge to beat him. He carries two blades, his principal weapon a unique sword with a curved blade and a hilt with two prongs sheathed across his back and the other a small tantō concealed at the end of his scabbard (only resorted to as a trump card). His main weapon appears to be an amalgamation of the Okinawan sai and Japanese katana. Mugen also has a tendency to parry attacks with the steel base of his geta.
