Tekketsu (鉄血, Tekketsu) is a fanon character of the Naruto series. He is a former resident of Kirigakure, as well as a current member of Akatsuki. He is most famously known for the large weapon he carries around - a sickle-like sword. A unique trait among the Akatsuki members is that he recieved little to no official shinobi training, relying on the art of swordsmanship more than anything else.
