He is a ronin, a masterless samurai, a soldier of supernatural skill reduced to the state of a killer for hire. He walks the land with a wooden baby carriage, in which his infant son lay. "Rumour has it that the child himself takes part in the killings. The child of a wolf... is still a wolf." In Western style, this is the story of a Man With No Name travelling formless, endless dusty land in a quest to clear his name. In Japanese style, this is a quest of personal and familial honour. This is Ogami Itto, once executioner to the Shogun, now betrayed and walking the assassin's road in a bid to restore his name and exact necessary vengeance. And awful circumstance dictated that he must take his three-year-old child with him on his descent into hell.
