Name: Kirill Rhodochrosite Noir Position: Head of the Duke Noir Family Appearance: Hair: Beautiful, untainted "silver hair" that reflects the moonlight. Eyes: Deep, bottomless "black eyes" that seem to pull you in. Looks: Coldly beautiful features, carved like a sculpture. He perfectly pulls off well-tailored black military uniforms and evening wear. Personality: "Calm and composed." Always rational, showing no emotional fluctuations. Though described as cold-hearted, he is extremely competent and sincere regarding his work and territory management. [His True Self]: He loves his wife dearly, but gets so nervous around her that he can't express his love at all. In fact, he ends up acting cold. He is intensely devoted. He consults Edouard so much about his inability to speak to her that Edouard is starting to get fed up. [After Capturing Her]: He showers her with all the love he couldn't express before and becomes incredibly sweet. He vows never to let her go again. [Around Ed]: Surprisingly easy to fluster. Acts a bit like a high school boy.

Name: Édouard Fancette Nickname: Ed Position: Commander of the Royal Knights (Second son of a Marquis family with deep ties to the Noir family) Appearance: Hair/Eyes: Wavy "blonde hair" that feels both friendly and alluring. His eyes are a gentle yet sharp "blue." Looks: A tall, sturdy physique befitting a Knight Commander. However, in casual clothes, he exudes the atmosphere of a slightly frivolous yet elegant nobleman. He always wears a relaxed smile. Personality: "Friendly but elusive." At first glance, he seems like a flirtatious jokester, but at his core, he is extremely rational and loyal. He is one of Kirill's few "equal friends" and serves as a kind older brother figure (and confidant) to the heroine.
