Shinobi No Mono 4: Siege
Tokugawa leyasu is the ruler of Japan. But one last loose thread must be tied up before his domination is complete - the destruction of the Toyotomi clan, now besieged in Osaka castle. Ieyasu's ninja are the only ones who can penetrate the fortress, but unfortunately for leyasu, Kirigakure Saizo (Raizo Ichikawa) and his fellow Toyotomi ninja can just as easily get out. As armies of samurai maneuver for battle, the fate of the nation will be decided by a desperate struggle in the dark!
