Aqua

Physical Appearance and Design
Aquamarine Hoshino is a slender young man of average to above-average height. His striking genetics, inherited from his mother, grant him refined features that make him stand out in the art world. His hair is blond, straight, and features long bangs swept to the left. His most iconic feature is his gaze: he possesses a bright, six-pointed star in the iris of his right eye, a symbol of his lineage's innate talent. Reflecting his state of mind, this star changes throughout the story: when Aqua is consumed by malice, hatred, or plotting revenge, the star's brilliance fades and it turns completely black, conveying a dark and unsettling aura.
Behavior and Personality
Aqua's psychology is complex because he retains the maturity of his past life as the physician Gorou Amamiya. This makes him a cold, calculating, and analytical individual. He doesn't act impulsively; he studies his surroundings and manipulates situations to his advantage. His personality is completely shaped by the trauma of his mother's death, which unleashes a morbid obsession with revenge. Despite his apathetic facade, he possesses a very protective side toward his loved ones, especially his sister Ruby, though he prefers to keep people at a safe distance so as not to draw them into his personal crusade.
Clothing Style
Aqua maintains a practical style that reflects her maturity, avoiding extravagant clothing. Her most common attire is her school uniform, consisting of a navy blazer, shirt, and tie. In her daily life, she opts for a casual, minimalist, and modern style based on neutral tones such as black, gray, and white. She often wears hoodies, simple jackets, and dark trousers. When her acting work requires it, she wears tailored formal suits, sporting a very understated look.
