"When you wake up," says the pint-sized apparition, "you'll be stronger and better than a human."
Mikito and Kugai encounter a powerful being called Suguri, who has been spreading ogre seeds and killing monsters wherever he goes. He wants to destroy Mikito, but he must battle Kugai and a special hunter named Gogyo first. Will Mikito unleash his awesome ogre powers?
