Karin, a small, peaceful island in the Pacific Ocean, is threatened by a storm which destroys the thatch houses on the island. Three monstrous shadows suddenly show up behind the storm, leaving the people on the island to believe it is the sign that the devils are awakening. An elder tries to persuade Prince Cab to evacuate with the other people, however, Cab refuses to evacuate and wants to fight the "devils". Lightning then surges from the bat monster's eye and hits the elder. Cab fights back by throwing a spear toward the shadows, but the spear is soon broken against them.
