Watch The Great Yokai War
All folklores tend to carry a similar pattern in dreaming up a young boy who is chosen or destined to save the world. Hold your dramatic pauses, this story has a somewhat terrifying twist to it. Yokai are not simply spiritual creatures of lore and religion, they are man-eating beasts of another realm. In another sense, Yokai tend to just do what they want. While they do have their weaknesses, who's to say a young boy could find the weakness of an 80 foot skeleton?
