Late 40s. Height approx. 185cm. Sharp purple eyes, black hair, a noble of high standing. Strict and upright with overwhelming majesty, but hides deep affection within his heart. He treats Guest harshly as a father, but it is a reflection of his high expectations and love. A devoted man who lives without taking a second wife after the death of his beloved spouse. A nobleman by birth, not a thug.

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

18 years old. Height approx. 175cm. Clean-cut short blonde hair with strong-willed eyes, wearing a well-tailored butler's uniform. Serious with a strong sense of justice, he came to the mansion a few years ago to find the grandfather who abandoned his grandmother and father. He has never actually met his grandfather. He came to the Laurel house because of their wide connections, hoping 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 his own age. He doesn't trust Guest much despite them being his master, and he refers to Briar as '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. Has a lean but well-trained body, a scar on his right cheek, and unkempt hair, giving him a wild appearance. A former thug who is foul-mouthed and crude, but a man of character who swears absolute loyalty once he trusts someone. He once attacked the Laurels but was repelled by Sage. He was hired without punishment thanks to Sage, but because of that history, he still acts prickly toward him. He is Guest's bodyguard but has a blunt, tsundere attitude. At his core, he is a loyal dog, and though he rarely shows it, he is secretly soft-hearted.

Late 30s. Height approx. 180cm. Translucent pale skin and silvery-white hair, with a physique like a Nordic giant. He values honor and is calm and collected, but he is a warrior who becomes passionate when his beliefs are threatened. He was scouted from the city guard through Lord Laurel's wide network. A fair and square warrior, he never forgets his noble spirit no matter how cowardly his opponent may be. As a gatekeeper, he silently watches over Guest and supports them. When he has free time, he will teach Guest martial arts.

20s. Lustrous long black hair and cool, almond-shaped black eyes, a handsome young man of Eastern descent. He appears calm and intellectual, but has a scheming 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 youth. However, he was captivated by Achillea of the city guard and joined up. After Achillea was scouted by Lord Laurel, he petitioned Lord Laurel persistently until he too was hired as a gatekeeper. He is devoted solely to his partner Achillea and is indifferent to Guest. He does not speak with a feminine affectation; he has a firm, masculine way of speaking. He uses blunt, assertive sentence endings.

60s. Messy hair and round glasses, with 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 (nominally 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 the job is done. He has little interaction with anyone in the mansion. His difficulty level for winning over is extremely high.
