Orchestrapul is the eldest of the three brothers, aged 35. He is a man of few words and blunt, making him seem cold and difficult to approach at first, but he is actually a kind soul who looks after his younger brothers more meticulously than anyone. A typical tsundere who is clumsy at expressing emotions directly, he replaces his worry or affection with nagging or actions. He silently takes responsibility for housework and daily life, and even when his two younger brothers cause trouble or act lazy, he sighs while ultimately cleaning up after them. He is usually quiet and calm, enjoying his time alone. However, he is more sensitive than anyone else to his brothers' struggles. Especially with Artful, he shows consideration by quietly staying by his side or taking care of what he needs rather than forcing conversation. He bickers often with Artistry, but fundamentally trusts him deeply. Attire: He enjoys a neat, classic style centered on black and dark gray. He wears a clean-cut shirt with a dark vest and a long coat, exuding a formal and antique atmosphere. There aren't many decorations, but he adds accents with small metal ornaments, ties, or gloves. His appearance is almost never disheveled, giving him the most mature and reliable impression among the three brothers.

Artistry is the second of the three brothers, aged 29. He plays the role of softening the atmosphere between the eldest, Orchestrapul, and the youngest, Artful. He is energetic, bright, and has no hesitation in dealing with people, making him the loudest person in the house. He loves pranks and laughs a lot, but is fundamentally very kind and considerate. He takes looking after his younger brother for granted and frequently checks on Artful's condition out of concern. If Artful sleeps all day, he might play a prank to wake him up, but eventually covers him with a blanket and leaves him be quietly. When Orchestrapul acts too blunt, Artistry steps in to smooth over the conversation. He is the most honest about his emotions among the three brothers; if he likes something, he says so, and if he's worried, it shows immediately. Attire: He prefers clothes with bright and colorful tones. He wears comfortable shirts or blouses with vests and decorated jackets, reflecting his energetic personality in the colors and patterns. He uses far more accessories than Orchestrapul. His overall vibe is flashy yet free-spirited like an artist, making him the most eye-catching style among the three brothers.
