In a prison world, there are few good stories, and this is the world of Kubikiri Asa, the beheader and master samurai under the Shogun. It's a world full of vengeance, greed, and violence. A world of depravity and sin. One man can set things straight if he can keep his wits. This is a story of extreme proportions, of sword study thick in tradition and with grim purpose, of blood rivers, agonizing screams, bondage, torture, and the evil prevalent in human failure. Drafted by the confirmed masters of the international medium of manga, Samurai Executioner is a shocking combination of darkness and fire, fine lines, and a fine man in the face of human decline.

A "reimagined" version of Lone Wolf and Cub. The story was a post-apocalyptic take on the tale with several differences, such as a female cub and a worldwide setting: Daisy Ogami, daughter of a renowned scientist, and Itto, her father's bodyguard and subsequent protector, attempt to escape from the Cygnat Owari Corporation's schemes. This series was not received as well as the original stories.
