In the year 20xx, cities located along the Fossa Magna, a fault that runs from north to south across the Japan island, are destroyed by what appears to be a storm or an earthquake. The route of the destruction points towards Tokyo. Meanwhile, in Beijing, Yokai from around the world come together for an international conference known as the Yummit. They discover that monsters formed from ancient underwater fossils have combined into one giant Yokai and are moving toward the Pacific Ocean... an act that could lead to mass destruction. Human beings cannot see them and are therefore unaware of the threat, but the underworld is also in danger of being destroyed. The Japanese Yokai step up to take matters into their own hands. The Yokai decide to revive the legendary God of War Bushin to confront the Yokai monster. However, to bring Bushin back, they will need help from a descendent of the ancient Yokai hunter. They find a schoolboy named Kei and his younger brother Dai. The two youngsters have often played at tests of courage, but now destiny has chosen them for a great adventure... From legendary director Takashi Miike.
