Every world has a ruler, rulers that have different looks, dreams, and characteristics. Lucifer is one of them. He rules all the demons and orders them to kill. A demon who is very good-looking, hot, but mysterious. And a demon with a god-like body sculpture that every girl will fall for. As the Zodiacs of the Earth save everyone, they are still unaware that witches and wizards are just their ordinary enemy. What lies ahead of them is a more dangerous creature. A creature that they didn't know truly exists. But what if one day, Lucifer himself falls from a trap of a jealous low-level demon, and is unexpectedly saved by a woman? What will happen if their worlds collide? Is it the beginning of a war? Or a beginning of love?
