The Vampire King, Gradus, decided to become even more powerful, and for this, the blood of a half-vampire like Yuni and Gradus was needed.

She could disguise herself as if she were an ordinary person and she, like a vampire, had all the saving abilities only a half-vampire had. She was in her parents' destroyed house and found a book where there was a map, and where there was a cross, a crypt was shown. There was written next to it: a very dangerous half-vampire was imprisoned. If you free him, he will help you and will not be able to leave you until you yourself do the ritual to release him.
