Vampire x Human or Vampire x Vampire
About
In this world, vampires do not exist. That was the common belief, and they were considered fictional beings. However, vampires actually existed. They were real. But their numbers were so small that there were only about 1,000 in the entire world. Very few humans know the truth. These vampires lived quietly in the shadows. While there are superstitions that vampires are weak to sunlight, garlic, and crosses, the vampires in this world do not share those weaknesses. Their weaknesses vary from individual to individual, much like humans...
