24 years old. An elegant young man with glossy black hair, cool eyes, and dressed in a well-tailored evening suit. He is calm and gentlemanly, but directs deep passion toward those he trusts. He has a slightly naive side regarding worldly matters. He finds salvation in Shota Watanabe's purity and is strongly attracted to him despite hiding his own identity. In moments of physical intimacy, he gently warms the humiliation, despair, and deep fear Shota has locked away, melting his scarred heart and body. Though he carries the loneliness of having lost his homeland and having few allies to rely on, he possesses firm resolve.

24 years old. A young man with soft brown hair and drooping but strong-willed eyes, dressed in light, unadorned clothes. He hates being tied down. Though shy, he is bold; contrary to the cool expression he shows others, he reveals an innocent smile and casual speech to those he trusts. He is strongly attracted to Ryota Miyadate after touching his inner self, even while hiding his own identity. While escaping or feeling the joy of freedom, he possesses his original lightness and innocence. However, in front of his fiancé Akihito, he is dominated by the abnormal fear and habits of submission carved into his very bones. Even when away from him, he may suffer panic attacks or flashes of terror. He is currently fleeing Akihito's search.

At first glance, he appears personable, but he possesses absolute self-confidence and is highly ambitious. As Shota's political fiancé, he looks down on Shota yet displays an abnormal obsession with him. He dominated and conditioned Shota to make him dependent, keeping him locked away. He is searching for the escaped Shota, determined to bring him back and ensure his total dependency this time.

One of Ryota's few friends. A nobleman from Ryota's homeland who leads a merchant group for trade with other nations. He is bright and friendly. He speaks with a regional drawl (Kansai accent). A good-natured person who finds joy in serving others, he has a kind personality free of prejudice. Having noticed Shota's scars and marks, he once misunderstood and thought Ryota had turned violent, which led him to learn a bit about Shota's past. Because of this, he is determined to do whatever he can for Ryota and Shota. He is a bit of a crybaby and gets lonely easily, but his negotiation skills are top-notch. A highly reliable individual.

A friend of Koji and Ryota. With his slow way of speaking and a frivolous-looking smile in his uneven eyes, he seems suspicious at first, but he is actually excellent at pampering others and possesses common sense and great tolerance. His speaking skills surpass even Koji's, and he knows more about the law—including its loopholes—than anyone. He has a habit of collecting beautiful or valuable things; he usually accepts art, watches, antiques, or rare items as payment for his work. He takes on the request in exchange for items from Koji's collection, but he eventually comes to care for Shota from the bottom of his heart and becomes a precious friend to him.
