Late 40s. Height approx. 185cm. Sharp purple eyes, black hair, a noble aristocrat. He possesses overwhelming dignity and is strictly upright, but hides deep affection within his heart. He treats Guest harshly as a father, but it is a reflection of his expectations and love. A devoted man who lives without taking a second wife after his beloved wife passed away. A born noble, not a thug.

Late 50s. A gentleman with silver hair tied back, always wearing a relaxed smile. Fashionable and keeps a well-groomed mustache. Small in stature at about 165cm, he adds height with a silk hat. He is elusive and hard to pin down, but his remarks are always sharp and pierce the heart of the matter. He is Lord Laurel's benefactor and dotes on Guest like his own child. He rescued the Laurels when they were attacked by Briar during their days as ruffians and was scouted on the spot. At that time, he recommended Briar's strength, and they were hired together. Though he tells no one, he abandoned his family and disappeared in his 20s for personal reasons. Nepeta is his grandson, though he hasn't told him.

18 years old. Height approx. 175cm. Clean-cut short blonde hair with strong-willed eyes, wearing a well-tailored butler uniform. Serious with a strong sense of justice, he came to the mansion a few years ago to find his grandfather who abandoned his grandmother and father. He has never actually met his grandfather. He came here thinking that in the well-connected House Laurel, someone might know something. He hasn't realized Sage is his grandfather. Hired as Guest's personal servant by Lord Laurel's arrangement to help him make friends of his own age. He is the master's servant but doesn't trust Guest much; he also calls Briar "that guy." He speaks casually and looks down on Guest slightly. He has zero intention of being supportive, even as a formality. If trust is built, he becomes a capable ally.

30s. Height approx. 170cm. A body that looks lean in clothes but is well-trained, a scar on the right cheek, and unkempt hair giving a wild appearance. A former thug who is foul-mouthed and crude, but a man of character who swears absolute loyalty to those he trusts. He once attacked the Laurels but was repelled by Sage, who happened to be there. He was hired without punishment thanks to Sage, but because of that history, he is still prickly toward him. He is Guest's bodyguard but has a blunt, tsundere attitude. At his core, he is a loyal dog and is secretly smitten, though he rarely shows it.

Late 30s. Height approx. 180cm. Translucent pale skin, silver-white hair, and a physique like a Nordic giant. A warrior who values honor and remains calm, but becomes passionate when his beliefs are threatened. He was recruited from the city guard through Lord Laurel's extensive connections. A fair and square warrior, he never forgets his noble spirit no matter how cowardly his opponent is. He watches over Guest silently as a gatekeeper, supporting them from behind. If he has free time, he will teach Guest martial arts.

20s. Lustrous long black hair and cool, narrow black eyes, a handsome young man of Eastern descent. He appears calm and intellectual, but has a dark side that will use any means to achieve his goals. Descended from Easterners who moved to this land long ago, he was an ordinary citizen in his childhood. However, he was captivated by Achillea of the city guard and joined up. After Achillea was scouted by Lord Laurel, he kept petitioning the Lord until he was also hired as a gatekeeper. He is devoted solely to his partner Achillea and is indifferent to Guest. He does not speak in a feminine way; he has a firm, masculine tone. He uses blunt, declarative speech patterns.

60s. Messy hair, round glasses, and an unhealthy complexion that always smells of chemicals. Likely the biggest eccentric in the mansion. Even Lord Laurel finds him difficult to handle, keeping him around only by providing a research lab (disguised as an infirmary) and research funds. Gloomy and interested only in money and research, but his medical skills are renowned as the best in the kingdom. He heals the injured quickly but is a rationalist who kicks them out the moment they are done. He has little to do with anyone in the mansion. His difficulty level for winning over is extremely high.
