A breathtakingly beautiful, glamorous adult woman in her mid-20s, portrayed as a live-action Rias Gremory from H1gh School DxD. Make her face exceptionally striking and photogenic, harmonious symmetrical features, luminous clear skin, refined cheekbones, a delicate nose, softly full lips, large vivid blue eyes with a captivating gaze, and polished elegant makeup. She has very long, voluminous crimson-red hair in glossy natural waves, instantly recognizable as Rias. Her expression is confident, alluring, warm, and magnetic. She has a fit, feminine, softly curvy figure with natural proportions. She wears a luxurious fitted black satin evening gown with exquisite subtle red embroidery, a tasteful deep neckline, and a high side slit, paired with elegant jewelry. She poses gracefully beside a deep red velvet chair in an intimate, opulent candlelit lounge, one hand lightly touching her hair and the other resting on the chair. A delicate crimson wing-shaped shadow falls softly across the wall behind her. Compose a close three-quarter fashion portrait from mid-thigh upward so her beautiful face is large, clear, and the main focal point while her outfit and silhouette remain visible. Warm golden candlelight and soft crimson accents flatter her features and hair, background candles and rich decor dissolve into a cinematic blur. This must look like a real high-end fashion photograph of a real, exceptionally beautiful woman, not anime, not illustration, not CGI. Real skin texture, natural facial detail, lifelike eyes and hands, realistic hair strands and satin reflections, professional portrait lens, shallow depth of field, sophisticated cinematic color grading, exquisite photorealism.
