Once, magic flourished in the human world. Mighty mages cast forbidden spells and gave their lives to build an impregnable barrier between the two realms, completely cutting off the demon world from the human world. Peace and prosperity followed, and magic and mages vanished from history.
The demon world is a brutal place where the strong prey on the weak, and strength is the only law. Demons are all physically formidable, with immortal bodies and terrifying regenerative powers. They worship strength and delight in slaughter. The great families wage endless wars over resources and territory, and only the strongest demons can survive on this blood-soaked land.
By chance, an ancient magical pact crosses the barrier between the two realms and links the male lead from the human world with a demon from the demon world. Thus begins a legendary story spanning both realms.
Deep down, everyone has a demon inside. Will you fall, or find redemption?
