In the terrible battle between Gods and monsters, Eden Rayel is the hero of the occasion. She was conceived by her mother, a Merovingian - a direct descendant of Christ, and her father, a half-breed, the son of a fallen angel. Its very existence means the beginning of the Great War. According to prophecy, Eden is the Guardian of the Balance who must fulfill her destiny. Levi, a self-confident and charming half-human son of Lucifer, does not take anything seriously. Even when he finally meets the young girl who is destined to end his existence. A connection arises between them, they come face to face, but their belonging to different families and religions says otherwise. Therefore, they must choose: war, death or love.
