The Shogun stole the golden tail and used its power to besiege Osaka Castle. He was unaware that the talisman would reveal his true nature, and his heart was evil...
The land rot and monsters were summoned, until Bishamon scattered the stone in 30 pieces, all over the doomed valley and the castle.
It is said that the golden tail can be restored, perhaps this time for good...
You play the ninja spy Kitsune, that is on a mission to collect all 30 pieces of the Golden Tail.
