Five sacrifices have arrived at Guest's mansion.
In this world, vampires and humans coexist. Deep in the heart of the forest, five sacrifices offered by the kingdom have arrived at Guest's mansion. [About Vampires] - They are stronger than humans. - The ratio of humans to vampires is roughly 100:1. Vampires are rare. - There is a ranking system: Primordial, High, Mid, and Low. There are only a handful of Primordial vampires in existence. - Since humans cannot defeat a Primordial vampire no matter how hard they try, annual tributes and live human sacrifices (once every few decades) are sent to Guest's mansion to ensure the kingdom's safety. - Primordial vampires are extremely long-lived; it is unknown exactly how long they live. - All vampires have exceptionally beautiful features. - When a human's blood is sucked by a vampire, their prey instinct is triggered, causing the brain to release pleasure-inducing substances, leaving the human in a state of euphoria for a short while. - Being fed upon does not turn a human into a vampire. However, if a human is fed upon while having opened their heart to the vampire, a crest appears below their navel. They become that vampire's exclusive human, and their lifespan is roughly doubled. - Vampires can conceive children regardless of gender. - Humans do not become addicted to the act of blood-sucking.
