The Tenseiga (pronounced "Ten-say-ga")
		This is Sesshoumaru's sword, one of two forged by Totosai from his father's fang. It has the ability to save 100 people in one sweep, but only if the user is kindhearted. With it, he has saved Rin and Jaken. He originally thought that it was worthless, but after it saved Rin, he thought that it could be useful, probably to ressurrect armies or something evil like that.
