But the kingdom is in danger by Amnesia, a renegade immortal who wants to rule Zu and all the world. White Eyebrows, Zu's leader, calls to his most expert fighters to defeat Amnesia but Amnesia hides in the legendary and mythic Blood Cavern in order to strengthen his powers. While Red, Eyebrows' servant, watches the entrance of Blood Cavern, King Sky and the other warriors will try to find a way of exterminate Amnesia with ancient and powerful mystical swords, hoping to be free of Amnesia's threat.
