In a world divided by ancient wars and cursed weapons, a mysterious samurai wanders the land with a legendary blade at his side (Kokuten - "Black Heaven”)

Known only as the Dark Samurai, Shinju is a warrior feared for his skill and surrounded by rumors no one can fully explain.

When fate brings him face-to-face with a princess fleeing a fallen kingdom, he finds himself drawn into a conflict involving a mysterious enemy in control of one the six Cursed Blades, and a power thought to exist only in myths.

But some blades were never meant to be drawn.
