Thanks to an oath, Mana had been forced to become a living cage of the god Miazanoapte. But his sudden awakening after fifty years has ruined the plans of the gods who are now forced to think of a new alternative. Because Mana was pure voratomores, his body was ideal for the god Miazanoapte to steal. That's why many of the gods decide to kill him immediately, certain that Miazanoapte will never find a living voratomores to steal his body. The first to doubt the decision is the god who found him and delayed his death for a month until the new sorcerers' competition where Mana had to show what he was capable of. But because a problem will never come on its own, his lack of memories and weaknesses from birth would prevent him from having an easy path. Placed with other human children, some of them natural-born talents, Mana must learn to overcome his disadvantages to earn the right to live.
