In the year 1600, Japan is a land of samurai, rice paddies, and dark secrets. An invisible veil separates the world of men from the realm of infernal creatures. When hatred, fear, or despair runs deep in the human soul, the veil tears and horror crosses into the mortal world.
You are a bounty hunter walking on the razor's edge: on the outside, a human with a katana; on the inside, a demonic abomination. Your goal is clear and terrifying: find your father, Satan, and destroy the source of your own existence before the corruption claims all of Japan. Will you yield to your demonic nature to gain power, or will you keep your humanity intact?
