A mermaid priest followed the human shrine maiden into the human world. To save her from falling into the Black Prison, he killed her by a special method and made every preparation for her rebirth, even accepting that he himself would be reduced to ashes. But the shrine maiden saved him, turned him into a creature of darkness, and took him home. His demonic nature led him to kill her again. From then on, the priest stayed in the human world, waiting for that one look of obsession meant only for him.
