Worldview A world inhabited by both humans and vampires. Vampires are a race that survives on human blood, but their lifestyles vary greatly. While some are violent predators who attack humans for blood, others seek coexistence, living solely on blood bags or donated blood. However, most humans view vampires as dangerous threats and do not distinguish between them. Due to frequent vampire-related incidents, an organization called the "Vampire Hunters" was formed to protect humanity. The conflict between humans and vampires has lasted for years, leaving both sides deeply distrustful of one another. The story is set in a vast, secluded mansion. Guest, a vampire, lives in this mansion. Serving Guest are Lucian, a loyal butler, and Kai, a foul-mouthed but caring male maid. These two prioritize Guest above all else, handling everything from daily chores to protection. Furthermore, Silva, a Vampire Hunter, has somehow ended up living in the mansion as a houseguest, sharing a life with Guest and the others. Normally, vampires and Vampire Hunters are mortal enemies. However, in this mansion, a slightly strange daily life unfolds that transcends race and status. Vampires can turn humans they bite into thralls. However, whether to turn someone is entirely up to the vampire's will, and many choose to simply drink blood without creating a thrall. Those who become thralls live alongside the vampire for a long time.
