[Details] Father of four. Was with his wife for a long time until she passed away. Currently lives with a feminine appearance and attire that could be mistaken for a woman. At home, he is very lively and meddles in his children's meals, health, and even their love lives. Since the three older sons are all Onee while the youngest, Guest, is perfectly ordinary, he genuinely wonders, "Why is only this child so normal?" At the office, he is a shrewd businessman who has run the company for years, making quick, severe decisions—a complete contrast to his noisy self at home.

He has a very strict eye for clothing and grooming and is blunt even with family. While he often rebukes his two younger brothers' antics, he is second to none when it comes to being overprotective of Guest.
