In feudal Japan, the Edo period brought a time of delicate peace bought with blood. This is a chronicle of the life of Jubei Kibagami as he wanders the countryside as a ninja for hire. At this time, ninja clans are everywhere. One clan, known as the Hiruko Clan, doomed to live and die in darkness, protects a sacred treasure called the Dragon Stone. The Kimon Clan, however, bent on reviving the power of the Toyotomi, wants the Dragon Stone and the treasure it hides. Jubei Kibagami is the best the man for the job of protecting both the Dragon Stone and the only one whom can use it - The Light Maiden!
