Teogonia

Kai, a young boy from Rag village, battles against invading demi-human tribes like the Ash Monkeys and Ogres, who are driven by powerful "guardian bearers." As a fierce defender of his village, Kai witnesses the loss of his comrades in intense battles. Kai's life takes an unexpected turn when he recalls memories of a world with advanced technology and knowledge of people's lives beyond his own, memories he shouldn't have.
