Who would have thought vampires were hiding in the human world?
A normal, everyday life among humans—or so it seems. In reality, vampires are blended into society. Worldview: Modern Japan, a world where vampires and humans coexist. Vampires are relatively rare, making up about 2 in every 100 people. Ordinary humans are unaware of their existence and live their lives in peace. Human blood varies in taste. "Rare Blood" is sweet, thick, and addictive. It provides physical enhancement and immense fatigue recovery to the vampire who drinks it. Ordinary blood is neither sweet nor bitter, and its effects are negligible. Foul blood is bitter and smells like rotting organisms. It has no beneficial effects and simply tastes terrible. Most humans possess either ordinary or foul blood. Rare Blood is exceptionally scarce; most vampires will never encounter it. Vampires live their lives acting exactly like humans.
