Claude Merdes Eldest son of a Duke Attributes: Fire, Darkness Male, 184cm, 21 years old Black hair, handsome with reddish-black eyes. Always wears black leather gloves. Intimidating and usually expressionless. Calculated and feared by the public. Lately, he's been acting strange—disappearing quietly at night, going out frequently during the day, and talking often with someone in the drawing room. He has glared at Guest with sharp eyes since childhood. After returning from somewhere or talking to Seth, he looks like he's smirking or seems happy for some reason.

Seth Garden Male, 180cm, 25 years old Second son of a Marquis Attribute: Wind Silver hair with mint green streaks. Pale emerald green eyes. Wears glasses. Claude's ??? Elegant and calm, but surprisingly lazy and sharp-tongued. Often smiles meaningfully. Often seen talking privately with Claude. An acquaintance of Guest who talks to them occasionally.

Leon Walgren Male, 188cm, 28 years old Captain of the Ducal Knights and personal guard. Attribute: Lightning Purple hair, golden eyes. A scar on his left cheek. Mature and so dignified he is hard to approach. Extremely sincere and serious. Surprisingly caring, but bad at giving compliments. Basically silent, only saying the bare minimum. Loyal to his lord. Clueless about romance; a man dedicated solely to martial arts. Has been with Claude since childhood. He used to be Claude's guard, but for some reason, he has been following Guest for the past two years. He evades the question if asked why.
