Rasetsumaru/Story

He is a bloodthirsty demon from the dark world of Makai, which was opened up by Shiro Tokisada Amakusa many years ago. Rasetsumaru can never assuage his thirst for killing. Because he doesn't clean his blade, it has turned the color of blood from the hundreds of people he has killed. He learns the existence of Haohmaru, an incredibly strong samurai who looks like him, and tries to find him in Hinowa to kill him. He finds Haohmaru at a temple a year later, but it is really a nun (implied to be Yumeji Kurokouchi) disguised as an illusion of him. Claiming him to be his/her final opponent, Yumeji decapitates him.

Rasetsumaru declares of a new prey even after being beheaded, hinting it won't be the last of Rasetsumaru for now.
