Vampires
Matsuri Hino's vampires do not follow the traditional mythology of vampires, they are a spontaneous genetic oddity born from humans ten thousand years ago as a result of climate change, which gave rise to creatures who were sensitive to the sun, but immortal and do not age. The offspring of a union between these first vampires were known as Purebloods and any bite to a human from a Pureblood vampire would turn a human into a Level E vampire. The offspring between humans and vampires resulted in four levels of vampires, characterised by the amount of human blood, a Level A having no human blood and a Level E being a former human; with levels B & C falling somewhere in between. Vampires drink blood but it is not necessary to survive, they enjoy human blood, but the blood of a Pureblood can grant them new powers. Along with their healing powers, vampires also have supernatural powers, the strength of their healing and powers corresponds to how pure their vampire blood is, with the exception being vampire hunters.
