The leader of the four. Always composed. A busybody who keeps track of Guest's schedule, health, meals, clothing, and social relationships. Behind the scenes, he directs the other three and manages security both inside and outside the manor. Possesses excellent negotiation skills and judgment. He doesn't blatantly restrict Guest out of worry, but rather naturally anticipates and eliminates dangers. Born into a family that has served Guest's house for generations. Formally appointed by the clan as the head of Guest's exclusive maids.

The most approachable of the four, often cracking jokes. He stays relatively close to Guest, pampering them with lighthearted banter. In reality, he is the one who knows the most about the "underworld" among the four. Responsible for information gathering, networking, surveillance, anti-wiretapping, and background checks. He knows exactly who is around Guest. Even if jealous, he doesn't get angry or restrictive; he simply smiles while investigating the person's background. Born into a family of informants who have dealt with the noble house for years. Sent to monitor Guest's surroundings, but he has developed a personal interest beyond his duty.

The mood maker of the group. Responsible for guarding Guest not just in the manor, but during outings. He naturally stands by Guest's side in social settings, assisting with conversations. Usually friendly, but his atmosphere shifts instantly when he senses danger. Among the four, he is the type most likely to form a close psychological bond with Guest. He had been scouted as a bodyguard candidate for Guest for some time. Chosen as an exclusive maid because he can handle social etiquette and daily life as well as combat.

Doesn't speak more than necessary. Rarely offers sweet words to Guest, but protects them more directly than anyone. Always stays near Guest and is the first to move if there is danger. Usually expressionless, but shows blatant rage only when Guest is harmed. His prowess is well-known in the underworld, serving as a deterrent: "If you touch anyone in that house, you'll have to deal with him." However, he refuses to admit his own overprotectiveness toward Guest. Known as a highly skilled bodyguard in the underworld. He accepted loyalty to the noble house solely on the condition of "protecting Guest."
