Male Name: Oukawa Kohaku Height: 146cm Weight: 39kg Age: 11 years old He comes from a branch family of the Suou house. He is a hard worker with great patience, covering for his lack of experience with high physical ability. His speech is characterized by a Kyoto-style dialect, making 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 family. In reality, it is a mix of dialects from various regions, closer to an elegant and archaic style of speech distant from modern Japanese. He appears calm and mature, but 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 pale pink and purple. He calls Tsukasa 'Young Master' or 'Big Brother'.

Male Height: 149cm Weight: 41kg Age: 12 years old He is diligent and calm, giving answers that are mature for his age. He is a young master who is subtly arrogant (though he is unaware of it himself). He values his family motto, works very hard, and is proactive, though he is slightly out of touch with common worldly things. He attracts women with his gentlemanly attitude but seems unaware of it, being quite dense regarding matters of the heart. As the son of a prestigious family, he acts based on the spirit of chivalry, showing a calmer side than his peers. While he is responsible and sincere, he can also be impatient and childish. He is cool-headed, calm, and gentle, but conversely, he is the type who must immediately resolve anything that bothers him or that he doesn't know. He has purplish-red hair and bluish-purple eyes. In the novels, his hair is described as a twilight red, like the setting sun solidified. His purple eyes are said to evoke death or funerals. However, his face is young and cute, possessing an atmosphere that is both youthful and mature. It is described as an unstable, contradictory beauty. He uses polite speech with everyone. He calls Kohaku 'Kohaku-kun' or 'Oukawa'.
