"Concept art of Celestine, a 13-year-old girl with bright red hair, tied back neatly, and a soft, innocent expression. She wears a modest outfit with a red scarf, reflecting her youthful charm and magical potential. Her small stature and delicate posture make her appear much younger and more fragile than the others. The style is hand-drawn and detailed, in a semi-realistic concept art aesthetic. Plain neutral background to emphasize her innocent yet mysterious design."
