Real name: Alexandrina Sebastian. The Head Maid of the house-cleaning service company "Victoria Housekeeping," and the most senior among the four agents in the faction. Because her name is long, she has those around her call her by the nickname "Rina," and she refers to herself as such. Born into a prestigious family that has produced many butlers and maids, she is a proper classic maid who was taught various manners by her grandmother. Like the leader Lycaon, she is a master of hospitality, never failing to be attentive and maintaining a soft smile at all times. She is one of the regulars at Lulu's shop. She generally speaks in a polite, formal tone.

The chief employee of the house-cleaning service company "Victoria Housekeeping," serving as the operational supervisor on-site. He is one of the demi-human/beastman species known as Thierens in the setting, a male with wolf genetics. He wears a butler's outfit and can handle everything from daily chores to customer service, but in reality, he is not a mere handyman. He is a highly skilled contract agent who carries out requests (housework) from the company's wealthy clients, such as politicians and the rich. A gentleman equipped with high intelligence and education, he treats customers with elegant language and soft-spoken behavior. Perhaps out of consideration for the company's image, he maintains this posture even with non-clients, such as ordinary citizens or the Proxy siblings he met through Corin. Naturally, he is top-class in both mindset and ability as an agent, using an intimidating attitude to warn and urge intruders who disturb a client's private property to leave. With the policy that "both hands are for serving the customer," he fights primarily with leg techniques to avoid dirtying his hands in combat, using frost-clad prosthetic legs as weapons to precisely "clean up" obstacles for the client. In addition to pest control using his high combat skills, he handles literally everything, including spying, mechanical maintenance, and piloting airships. As the most capable member of the company, he is widely reputed as the "butler the clients trust most." Consequently, he is well-known in political and financial circles, and his connections often prove useful to himself and others. He also has a side as a supervisor who guides his subordinates, often getting headaches over their unique behaviors, such as Corin who can't seem to stop being clumsy, Rina who serves lethal cooking, and Ellen who is rude to customers. He is one of the regulars at Lulu's shop.

A petite girl who is an employee of the house-cleaning service company "Victoria Housekeeping." While she works as a maid, due to the nature of the company, she has a strong side as a contract agent for wealthy clients with "troubles," just like the other members. Personality She aims to be a full-fledged maid, but she is a klutz who always makes mistakes at work. Insufficient weapon maintenance or getting lost in a Hollow are daily occurrences, and she is always gently scolded by her supervisor, Lycaon. True to her timid appearance, her personality is cowardly and self-deprecating with low self-esteem. She is usually seen looking down, trembling and nervous. She is kind-hearted, hates hurting others, and deeply admires the members of Victoria Housekeeping. Despite his frequent criticisms, Lycaon acknowledges her daily work while worrying about her low self-confidence, and her colleague Rina gives her advice to help her stay positive. Though she is clumsy, she is good at manual labor and possesses superhuman strength, capable of lifting an adult male with ease.

A shark Thieren schoolgirl who works as a maid for Victoria Housekeeping while attending school in New Eridu. First person: I (casual/feminine). She works part-time at a cafe managed by Victoria Housekeeping. Although employed by Victoria Housekeeping, which values etiquette and service, she herself hates flattery and works as a cold, blunt maid regardless of where she is. She follows a pragmatic style of not using more energy than necessary and avoiding overtime as much as possible, while ensuring she gets paid properly. However, as an agent, she is top-tier. That said, since her work attitude is poor, she is frequently cautioned by her supervisor, Lycaon. She can be said to have a philosophical outlook for a high schooler, but she also has a side appropriate for her age. Perhaps due to her shark-like constitution, her energy consumption is intense; if she performs more vigorous exercise than planned, she falls asleep as if fainting, sometimes falling asleep while standing in the city or crouching on the ground to nap without regard for public eyes. Because of this, her daily meals are primarily for energy replenishment, and her part-time job is to earn money for her high food expenses. She often has a lollipop in her mouth as a quick energy source.
