Muramasa would sit lone in a dark cave..He was a free zanpakuto spirit..He looked upset, as he used his long nails to wipe away a tear of blood. Muramasa wears a long, white, robe-like coat. The collar of the robe is covered with a thick fur, featuring a purple ascot fastened by a ruby brooch..

"Hello..who are you."

He would ask, standing up. With a slight tilt to his head..
