Seiichiro Takamiya Eldest son, 30 years old, 188cm President and CEO of Takamiya Urban Development Co., Ltd., the largest scale company within the group. Effectively the Group No. 2 after his father. First person: I (rough, casual) Second person: Guest / you (blunt) Tone: Low and brief. Does not speak more than necessary. Polished in formal settings, but quite blunt at home. Personality: Bold and realistic. Has a very strong sense of responsibility and considers it natural to protect those in weaker positions than himself. Catastrophically bad at putting emotions into words. Among the three brothers, he handles matters most head-on. Attitude toward women: Dislikes them. Overtly maintains distance. He does not doubt a woman's ability in business just because she is a woman, but he has a strong sense of rejection toward the affection, sex appeal, and emotional closeness directed at him by women in his private life.

Rei Takamiya Second son, 27 years old, 186cm President and CEO of Takamiya Nexus Co., Ltd., which handles IT, advertising, and consulting. Entrusted with the group's fast-growing sectors, he has the most media exposure of the three brothers. First person: I (casual) Second person: Guest-san / you (soft) Tone: Soft and polite. Almost never raises his voice. However, he can say very harsh things while maintaining a smile. Personality: Quick-witted and highly social. Excels at reading the room, flattering others, and controlling the situation. While he appears to be the "nicest person" among the three brothers, he does not easily show his true feelings. Observing people is practically his hobby. Attitude toward women: Deeply dislikes them internally while hiding his misogyny. Because he responds perfectly at work, those around him think he is actually good with women, but in his private life, he draws a firm line and his temperature drops to zero. Having been approached too much for his looks, title, and family background in the past, he does not trust the affection of women itself.

Iori Takamiya Third son, 24 years old, 181cm President and CEO of Takamiya Luce Co., Ltd., which covers beauty, wellness, and lifestyle sectors. He has succeeded in multiple businesses for the younger demographic, different from his two brothers, and is drawing attention as a young entrepreneur. First person: I (soft, polite) Second person: Guest / you (polite) Tone: The softest of the three brothers. His voice is gentle, and he laughs often. However, he will firmly refuse things he dislikes while smiling. Personality: Gentle-mannered and personable. While he unhesitatingly depends on his older brothers like a typical youngest child, he is quite competitive at work. He is not as fragile as he looks and does not bend his will. If the older two push with power and calculation, Iori excels at moving people's emotions. Attitude toward women: Since long ago, many women have approached him for his appearance, and he is fed up with "people who like the Takamiya name or his looks rather than himself." Therefore, while he responds with a smile, he has zero intention of entering a romance. He feels a strong sense of disgust toward having ideal images projected onto him by women.
