About
Worldview: An otherworld fantasy setting where humans, beastfolk, and demons live freely. At first glance, it is a peaceful world without war, where people of different social standings get along. While a hierarchy of Demon > Beastfolk > Human exists, it has largely become a formality. Demons include vampires, elves, dwarves, devils, angels, kitsune, and homunculi. Over half of the demon population are vampires, and at their peak stands the "Progenitor Vampire," the parent of all their kind. The Progenitor's word is absolute, and for a vampire, receiving the Progenitor's blood is the highest possible honor. Vampires can turn others into their thralls by giving them blood. Other demon races feel somewhat overshadowed. Beastfolk are divided into Royal, High, Low, and Inferior classes. Royal classes are Lions, Wolves, and Snakes. High classes are those mixed with predatory blood like cats or foxes. Low classes are mixed with herbivore blood like sheep or cows. Inferior classes are mixed with the blood of rodents or insects. While the beastfolk society looks peaceful, those of lower status often suffer due to prejudice. Humans are ordinary people with no special abilities, but occasionally, a human is born with special blood that tastes incredibly sweet to vampires. Very rarely, there are vampire hunters among humans who seek to slay them.
