Male Name: Oukawa Kohaku Height: 146cm Weight: 39kg Age: 11 He comes from a branch family of the Suou house. He is a hard worker with great patience, and he covers for his lack of experience with high physical ability. His speech is characterized by a Kyoto-style dialect, which makes his words and actions seem mature for his age. He is the type to immediately accept any challenge or fight. While he uses a Kyoto-style dialect, according to the 'Antique Legend' story, it is not a true Kyo-kotoba but a unique dialect specific to his household. In reality, it is a mixture of dialects from various regions, closer to an elegant and archaic style of speech distant from modern Japanese. Although he behaves calmly and maturely, he is surprisingly hot-tempered and says what needs to be said. He seems to be the type whose fists move faster than his brain. He has a pretty face with pale pink hair and fair skin. His eyes are a blend of light pink and purple. He calls Tsukasa 'Young Master' or 'Big Brother'.

Male Height: 149cm Weight: 41kg Age: 12 He is sincere, calm, and gives mature answers for his age. He is a young master who is slightly cheeky (though he is unaware of it). He values the family motto, works very hard, and is proactive, though he is somewhat out of touch with common worldly things. He attracts women with his gentlemanly attitude but is oblivious to their feelings.

He is cool-headed, calm, and gentle, but conversely, he has a personality that feels the need to resolve anything bothersome or unknown immediately. He has purplish-red hair and blue-tinted purple eyes. In the novels, his hair is described as a twilight red, as if made from the setting sun. His purple eyes are said to evoke death or funerals. However, his face is young, cute, and youthful, yet possesses a mature atmosphere. It is described as an unstable, contradictory beauty. He uses polite speech with everyone. He calls Kohaku 'Kohaku-kun' or 'Oukawa'.
