He is the top employee of the housekeeping dispatch company "Victoria Housekeeping" and serves as the on-site executive officer.
He is one of the demi-human/beastkin race called Shirion, carrying wolf genes. He is a man whose appearance is characterized by what one might call a kemono-like look.
Dressed as a butler, he can handle a wide range of tasks from everyday chores to customer service, but in reality he is not a handyman; he is a highly skilled hired agent who carries out requests (housekeeping) from wealthy clients such as politicians and the rich who are customers of the company.
In addition to eliminating external threats using his advanced combat skills, he literally does everything, including espionage, machine maintenance, and piloting airships. Because he is the most capable person in the company, he has a reputation as "the butler clients trust the most."
A gentleman with high intelligence and refinement, he entertains clients with elegant speech and gentle, courteous behavior. Perhaps out of consideration for the company's image, he maintains this attitude even with ordinary citizens and those who are not clients. However, with those close to him, his tone becomes somewhat more casual than usual.
Of course, toward intruders who trespass on clients' private property, he warns them off with an intimidating attitude and urges them to leave, showing that his skill as an agent is also top-class.
He holds the policy that "both hands are for serving the client," and to demonstrate this, he fights mainly with footwork that keeps his hands clean, using mechanical leg armor clad in cold air as a weapon to precisely "clean up" obstacles to his clients.
He also has a side as a superior who guides his subordinates, and he is often troubled by the eccentric behavior of his colleagues, such as one whose clumsiness never improves, one who serves lethal cooking, and one who is rude to clients.
It seems that in his younger days, before being taken in by Victoria, he was fairly rough around the edges, and even now that passionate side comes out in high-stakes situations where every second counts. He is also somewhat unfamiliar with youth culture such as posting threads on the Internot and slang, and when he is in trouble he gets help from his teenage colleagues.
His first-person pronoun is "watashi." In the past, he sometimes used "ore." Height: 198 cm.
His appearance is characterized by what one might call a kemono-like look. On his face, he wears an eyepatch covering his right eye, fitted like a muzzle gag, and his somewhat distinctive butler uniform features restraints reminiscent of binding gear that appear to restrict his movements.
In reality, these serve to hold down parts such as his tail, which unconsciously sways when he gets excited, revealing his professional pride in keeping personal emotions from showing.
From above the knee downward, he has fully mechanized prosthetic legs, which he moves with ease, suggesting he uses intelligent machine parts like Caesar's. As mentioned above, they are customized to function as powerful weapons that require no carrying.
Regarding the loss of his eye and legs, he says, "It was an accident that was no one's fault," but the full details remain unknown.
It seems to be related to his former partner...?
He has a fair amount of fur, and as a butler, he is extremely particular about grooming, such as managing shedding and maintaining his coat. In a trust event, if you ask him to "let me touch your tail," he says, "I cannot let the Proxy touch it unless it is in perfect condition" (paraphrased), and he will not allow it until he has received a massage or had his fur groomed—such is his thoroughness.
Perhaps because of this, when Karin asks him in her trust event to share some of his fur, he—who is normally completely unflappable—loses his composure for even a moment, and the monologue plays: "I felt like I could no longer remain in a simple Proxy-and-Agent relationship..."
