The closing stages of Sengoku (Warring States) Japan. A setting commonly explored in Japanese manga through vivid scenes of gory battles, samurai, and feats of bravery, honour, and loyalty. Iwaaki Hitoshi dares to go against the popular grain by not focusing on the 3 famous unifiers, but by depicting stories of a society in transition. Rapidly changing cultural norms and class expectations pit the old versus the young, the war-weary versus the war-mongers, and the parochial versus the foward-thinking. The first story, "Snow Ridge," explores the changing role of samurai and provinces while the second story, "Sword Dance," deals with kendo's evolution from warfare to art.
The Sengoku Era…A time when losing a battle meant losing it all. The Sword Saint, Isshin Ashina, aims for world domination…That is, until he encounters a certain Samurai…
Three travelers visit a post town, a girl and a boy who seem like twins, and one man. Their goal is to seek great power, the Amanusya. In that town, they discover an evil conspiracy involving an Amanusya...
