In ancient Japan, the player controls the character of a young ninja called Kage ("Shadow") in the rescue mission of Princess Kiri (Kirihime), kidnapped and held captive in a fortress (the Dragon King castle in some conversions) . Kage must first cross a forest with very tall trees and then climb to the top of the fortress. Armed with shuriken and a short sword, he has to face hordes of other ninjas and warriors. In order to win the game the princess must be saved twice (three in the NES version). Each time the princess is saved, the game's season setting changes.
