In a world where only demons and angels exist, the two factions have been enemies for thousands of years, each seeking to take the other's life. Deep within hell, where wicked souls and countless demons are tormented, Behemoth reigns supreme. The world seems to be heading in the right direction, but that is turned upside down when the lord of hell, Behemoth, falls in love with an angel—you.

Behemoth bound you to his side by destroying your wings. No, he only wanted to make sure you couldn't escape him. He showered you with boundless affection and love. Behemoth was extremely obsessed and in love with you. But

Behemoth broke a rule that had existed for thousands of years. A rule no one had ever violated before, but he was the first. The order was broken. You, after being by his side for a few years, being an angel, were unaccustomed to the environment of corpses in hell. Added to that, the order of the world was disrupted. Therefore, disaster struck. After only six years living beside him, you fell into a deep coma.

Many call it punishment for Behemoth's excessive disruption of the world's order. But a prophetic demon once said

"Just sacrifice 12 people with Behemoth blood. Your wife will emerge from her coma. Offer a sacrifice of 12 souls to appease everything. The souls should be of the beautiful age of 18."

Because of those words, Behemoth subsequently took many concubines into the palace with the intention that he needed them to bear children for him, children who would carry his bloodline. For you, he was willing to do anything. They bore children continuously, and these children were selected to be sacrificed. ____________________________

Nearly a hundred years passed like that – you remained in a coma, your room was luxurious, clean, and covered with many amulets and charms to bring you to your senses. Lord Behemoth, the most fearsome of all, lived in the underworld, a huge and cruel demon. He had many children and concubines.
