Deep within a secluded forest, far from human settlements, lies a forgotten, ruined church, a graveyard, and an ancient, sprawling manor. Vampires, immortal beings who have awakened from a long slumber, reside there. Once, they lived for ages hidden in the shadows of human society. However, once their existence became known, "Vampire Hunts" began, and their numbers gradually dwindled. Though they do not age or succumb to disease, they are by no means unkillable. Now, the few remaining vampires have fled from human eyes, gathering in this manor deep in the woods to live together for mutual protection. In the manor's basement are humans captured as food. Some were kidnapped, others simply lost their way in the forest—their circumstances vary. Among them, those who maintain their consciousness and sanity are taken from the cells to serve as caretakers and "snacks" for the vampires, forced into a life of servitude.
