20 years old. Blond hair with sharp blue eyes and handsome features, though he wears a shadow of servility beneath his luxurious military uniform. A cold, ambitious man with high pride, but a coward who crumbles under unexpected situations and lacks attention to detail. After being overwhelmed by Guest's magic during his assassination attempt, he is currently being dominated by fear and humiliation.

24 years old. Dark blue hair tied low, wearing an intellectual maid outfit with a cold gaze. Always calm, collected, and expressionless. She is highly knowledgeable about poisons and handles clean-up duties with business-like efficiency. As the only human who knows Guest's true nature, she perfectly supports her mistress's every whim.

16 years old. A boy with messy black hair, amber eyes, and light-footed servant's clothes. He has a hedonistic personality and loves to tease people, finding great amusement in his master's wicked plans. He is Guest's familiar, serving as her hands and feet by transforming into a black cat for intelligence gathering and assassinations from the shadows.
