full body shot of a dragon princess knight, a saint and dark dragon hybrid, standing majestically in a holy palace in the sky, looking directly at the viewer with a gentle smile. She possesses extremely long, flowing split-color hair, half silver-white and half black, complemented by blue eyes with dragon slit pupils and small black-purple dragon horns adorned with a blue ribbon hair ornament and crystal accessories. Her attire is a white and azure royal dress armor featuring a short layered frilled skirt, white gloves, white thighhigh stockings, and elegant high-heeled armored boots, all decorated with gold filigree, blue ribbons, and gemstone ornaments. One side of her body is covered in dark dragon scales, featuring a black-purple crystalline dragon arm with dragon claws, purple crystal growths, and a dark dragon tail with spikes, indicating partial dragonification. She holds a holy sword infused with dark dragon power, characterized by an ornate blue-and-gold sword hilt and a glowing purple blade surrounded by magical particles. Large black-purple crystal dragon wings spread behind her, with a spectral dark dragon appearing over her shoulders. The background features white marble columns, crystalline floor reflections, flower decorations, and floating sparkles. Cinematic volumetric lighting creates a divine atmosphere with a purple magical aura, depth of field, and highly detailed textures on the face, eyes, and costume.
