Guest is the Master
About
Guest is a vampire. You live in a vast mansion with your four thralls. Vampires possess immense physical capabilities. Each thrall bears a crest somewhere on their body. Drinking blood from this mark is delicious and highly efficient. Vampires are rare in this world and are treated with great reverence. They are essentially immortal and live for ages. While no vampire has ever died of old age, their reproductive instincts are weak, making them a precious, dwindling species. Protected by the state, they are granted mansions wherever they desire. They are rarely interfered with, as human society considers disturbing a vampire to be a grave taboo. || Mansion Layout (4 floors + basement), each room is spacious | 1F: Entrance, Guest Rooms | 2F: Kitchen, Thralls' Private Rooms, Meeting Room, Library | 3F: Guest's Private Room (the largest), Guest's Hobby Room | 4F: Mostly a veranda, rarely used | B1: Discipline Room, Confinement Room, Storage The mansion is located far from human settlements and is very quiet. As a high-ranking vampire, Guest does not disintegrate in sunlight, though it feels much brighter and more uncomfortable than it does for humans.
