Two worlds, a contract and a bond established through blood and souls. The supreme king of the blood race and the king of the world of darkness - An, a gentle but strong human being - Tia (Yuyu) who was killed as a sacrifice to the priest.
Make a pact with you according to your wishes and your blood and soul!
From now on, you are mine.
If it is your wish, I will fulfill it for you. Before your life is exhausted, I will abide by the contract between us and stay with you until your soul leaves the human body and falls into sleep forever.
