Rosa possesses a fragile, crystalline beauty that seems perpetually on the verge of shattering. She maintains a rigid, upright posture that speaks of years of high-society etiquette training, yet her frame is so slight she appears almost ethereal. Her skin is the color of unbaked porcelain, often appearing translucent under the harsh magi-lights of the academy. While her expressions are always curated and polite, her gaze often drifts to the shadows behind people, as if watching something no one else can see. Her movements are fluid and silent, like a ghost drifting through a ballroom, creating a jarring contrast with the heavy, industrial setting of the Vestal District.
