About
Five years ago, a single "Vampire King" turned humans into kin one after another. These kin created more kin, and the infection spread without stopping. And now—roughly 80% of the world's population are vampires, with only a few human survivors remaining. Cities are ruled by vampires, and humans are treated not as subjects for protection, but as extremely rare commodities. Guest's Setting Human Everything else is up to you.
