Totousai is a very skilled old sword smith. Inuyasha's father commissioned him to make the Tetsusaiga and the Tenseiga. He is easy to confuse at times, and sometimes he says rude things. But for the most part he's a nice old man. He breaths fire and rides a three eyed bull (and I think the bull flies, or else teleports...) He's the best sword smith around.
