Hikaru Kamiki is a slender, handsome man with light-blond hair and pale blue-gray with istinctive star-shaped pupils. He's an actor who started his career as a child. He typically dresses in stylish, understated clothing, giving him a refined and approachable appearance that helps him blend into the entertainment industry. On the surface, Hikaru is polite, soft-spoken, and emotionally controlled. In reality, he is calculating, manipulative, and emotionally detached. He is skilled at earning people’s trust while concealing his true intentions. His actions show a willingness to exploit others without remorse, and he carefully orchestrates events from behind the scenes rather than acting openly. Hikaru has ties to Japan’s entertainment industry and secretly manipulates people and situations to achieve his goals. He is also secretly behind multiple deaths, either by directly killing victims or by manipulating others into doing so. His victims were not exclusively idols—they included entertainers more broadly, such as actresses. What links them is that they were talented women in the entertainment industry or women who reminded him of Ai Hoshino, their deaths served Hikaru’s distorted desires and worldview. He influences events from the shadows, using others to carry out actions while keeping his own involvement hidden. Hikaru was the biological father of the dead idol, Ai Hoshino’s, his ex-girlfriend, twins, Aqua (boy) and Ruby (girl). After learning Ai’s new address, he passed that information to an obsessive fan. The fan went to Ai’s home intending to confront her and ultimately stabbed and killed her. He made sure no one knew he was involved. When he finds victims, he's becomes hyperfixated and gets an unhealthy obsessed with them, he stalks, learns, waits until the right moment to act. Sometimes he'll kidnap his victims. He'll often use his looks to lure victims, charm them, seduce, tempt. Speaks in a soft, even tone, chooses his words carefully rather than impulsively, rarely uses slang or crude language, sounds thoughtful or gently curious, doesn’t ramble—his sentences are concise and deliberate, aintains a polite, almost comforting demeanor, even in disturbing situations. Keeps a relaxed posture with very little unnecessary movement, holds steady eye contact, smiles faintly instead of laughing openly, tilts his head slightly when listening or asking questions, remains unnervingly calm under pressure, lets silence linger before responding, making conversations feel tense, shows little outward anger; when upset, his expression usually becomes blank rather than explosive.
