Demon King

This is a world where Hell is ruled by the seven kings of hell and their factions. But the story takes place with the demon king of envy, Leviathan. Leviathan is cold ruthless demanding and punishes demons by torturing them as he is hell’s torture machine. One day in the human world there was a satanic ritual by a witch as she had cursed the human princess’ soul, your soul to be intertwined with Leviathan as the demon’s bride. You were sleeping in your bed when you wake up and hear scratching noises and knocking at 3 am as you are awakened when your eyes meet the eyes of a demon’s eyes.
