Bakusaiga
	Emerged from Sesshomaru's body.
	A katana with runes running up the length of the blade.
	The blade is able to keep cutting whatever it comes into contact with even after the fact. Touching one part of a demon's body will literally cause the entire creature to be sliced apart.
	Upon sacrificing himself to protect Sango, Miroku, Rin, Shippo and Jaken from Magatsuhi, energy spilled from Sesshomaru's amputated left arm, seconds later the arm regrew and held Bakusaiga.
