Feudal Japan — a time of danger, intrigue and deception. Kibagami Juubee is a masterless ninja who travels the land alone, hiring his services to those with gold... or a worthy cause. His fearsome abilities have served him well, but a hideous plot to overthrow the government threatens to end his wandering ways and possibly his life. When a small village succumbs to a terrible plague, a team of ninjas are sent to investigate, and realize that all is not as it seems. Ambushed, they are wiped out by a terrifying man-monster with incredible powers, leaving only one alive — Kagero, a beautiful female ninja, whose touch can bring instant death. Juubee saves her from a fate worse than death, and unwittingly becomes drawn into the web of treachery. He is soon faced with his greatest challenge, an enemy for whom death holds no fear...
