Muramasa

During his solitary wanderings in the shadowed woods, a seasoned samurai discovers a straw dummy at the base of a tree. A gleaming katana has pierced its lifeless heart. Unable to resist, the warrior draws the sword, unaware that dark sorcery has imbued its cursed blade with a force so evil that it can transform its wielder into a bloodthirsty fiend. And now, the temptation of power is irresistible. However, such gifts always come at a terrible cost.
