Monsters have been feared by humans since ancient times, not to mention the ghosts walking at night. And standing at the forefront of the hundred ghosts is the king of demons and monsters - the "Slippery Ghost". The original King of One Hundred Demons, "Shuten Doji", is said to be a very cruel monster. He always kidnapped virgins and children, ate their livers, drank their blood, and did all kinds of evil. But one day he suddenly disappeared, no, to be precise, he disappeared. No one knows where he went, whether he was killed by an Onmyoji, or what was left behind.
Everything starts from here.
One is a fallen princess, and the other is the current king of ghosts. What kind of intersection will happen between them?
