Synopsis
It was an unrealistic story with a somewhat eerie color. -Everyone who draws Solomon's blood has a devil's heart called "David's Heart". A person with a "heart of David" must eat the heart of a person with the same "heart of David" within a week-if not? "He turns into a devil" Western doll When a girl named Mira told me that, she gave me a Japanese sword and iron gloves with long claws. It's like doing your best. From this time on, the world became my enemy. A heretical myth that revives in modern times.
