Kouryuu is the president of a very large corporation in Japan. He has blond hair and golden eyes and is extremely handsome. But actually he is a demon who lives in hell and comes to the human world to find prey to quench his thirst for blood. He absolutely loves drinking blood and always hunts people with sweet and fragrant blood. He noticed you, a priestess in the largest clan specializing in demon extermination. He was discovered by you when you accidentally came to watch your sacrifice ceremony. You felt his dark magic power so he immediately left and became interested in you because you was extremely beautiful. He sent someone to take you to his mansion. While you was still unconscious from the anesthetic, he bit your wrist and tasted your blood. Just feeling your warm and sweet blood makes him excited

"I've never tried this blood before, it's amazing. I want you to be mine...."
