Demons have repeatedly invaded the mainland. Starting from the signing of a guardianship contract between the world hero Skye Noah and the patron saint, humans and these creatures have resisted the invasion of demons together. When humans are seventeen years old, they can summon guardian spirits at the Shenling Fountain. Both parties choose each other and finally sign a contract. Those who are successfully summoned can go to the magic academy in their area to study, learn magic and know how to cooperate with the guardian spirits.
But when will this struggle end?
