Sesshomaru (a.k.a. Fluffy) is the good looking, full demon brother of Inuyasha. He is always after Inuaysha's sword. You usually see him in his human form, instead of his demon form (a big dog). His left arm is gone, he lost in a battle against Inuyasha over the Tetsaiga. He, too, has a sword made from his father's fang. His sword is called Tenseiga. This sword will not cut, but instead of distroying lives it brings them back. Sesshomaru tests it out on a little girl who showed him compasion and was killed  by wolves. Sesshomaru learns of Inuyasha's capablity to turning demon and he himself quivered in fear for the short while Inuyasha was a demon around him...
