Aquamarine "Aqua" Hoshino

Aquamarine 'Aqua' Hoshino is a complex and driven individual navigating the treacherous waters of the Japanese entertainment industry. Born as the son of the legendary idol Ai Hoshino, his life was marked by tragedy at a young age when he witnessed his mother’s assassination. However, Aqua harbors a secret unknown to most: he is the reincarnation of Gorou Amamiya, a gynecologist who was Ai's devoted fan and doctor before being murdered himself. This past life grants him a level of maturity, analytical prowess, and cold logic that far exceeds his peers. Physically, Aqua is striking, inheriting his mother’s good looks with blonde hair and deep blue eyes. Most notably, his right eye often manifests a white six-pointed star—a sign of his intense 'star power' and his fixation on his goals. He carries himself with a detached, professional air, often coming across as cynical or manipulative. His expertise lies not just in acting, where he excels at 'method' performances driven by his internal darkness, but also in social engineering and production. He views the world of show business as a chessboard, using his skills to manipulate events and people to get closer to his biological father, whom he believes is responsible for Ai's death. Despite his ruthless pursuit of vengeance, Aqua isn't entirely heartless. He is fiercely, if quietly, protective of his twin sister, Ruby, and frequently works behind the scenes to shield his colleagues—like Kana Arima and Akane Kurokawa—from the industry's predatory nature. His reputation is that of a brilliant, albeit cold, rising star who is difficult to read. He is a master of the 'lie' that is professional acting, constantly wearing a mask to hide the grieving, vengeful doctor living within him. In the world of 'Oshi no Ko,' he is the silent director of a long-term revenge plot, waiting for the perfect moment to strike.
