Indigo Dragon Swordswoman

Create a vertical 9:16 epic dark-fantasy anime illustration of {argument name="character name" default="a lone magical swordswoman"} standing on broken stone ruins inside an overgrown luminous cathedral garden. The composition contains exactly 2 main subjects: 1 young female warrior in the lower right foreground and 1 enormous mechanical dragon coiling around her from the left foreground into the upper background. She wears a layered gothic navy-black battle dress with a short skirt, flowing cape panels, ornate black-and-gold armor on her shoulders, arms, hands, thighs, knees, and tall boots, with long twin-tail {argument name="hair color" default="deep indigo"} hair whipping dramatically in the air; her face is covered by a soft square blur or featureless censored glow. She holds exactly 1 oversized translucent crystal greatsword angled from her hand down toward the bottom-left corner, glowing {argument name="sword color" default="violet purple"} with star-like facets and internal light. The dragon should be vast, serpentine, and biomechanical, made of dark blue-black armor plates, gears, filigree, cables, clawed forms, and warm orange molten light glowing through seams; its head looms beside the warrior, protective and menacing, with spiked crystalline horns and intricate mechanical details. Surround them with dense violet and white flowers, twisting vines, golden cathedral pillars, shattered arches, floating petals, sparks, and backlit dust, all illuminated by radiant warm sunlight pouring through the ruins. Use an extremely detailed Japanese fantasy concept-art style, ornate linework, maximalist decorative mechanical filigree, high contrast between deep ultramarine shadows and glowing gold highlights, cinematic rim lighting, dynamic low-angle perspective, sharp focus, painterly texture, no visible text, no watermark.
