During the Sengoku War, the shogunate assembled an elite unit of brutal and skilled samurai consisting of only five men: The Blades of Hakai. Each member is capable of slaying a hundred men. Even in war times, The Blades of Hakai committed unspeakable acts. The story begins at the start of the Edo Period in 1608 Japan. We meet a ronin samurai on a quest for justice and revenge against the members of The Hakai. The warrior's encounters with his foes lead him to question if the ends justified the means and the nature of men.
