哥特风动漫少女与机械巨剑

Create a tall vertical dark fantasy anime illustration of {argument name="character name" default="a white-haired battle maiden"} inside a ruined gothic cathedral-mechanical fortress. The single central character is a pale young woman with very long flowing {argument name="hair color" default="silver-white"} hair, sharp tired eyes, delicate anime features, and small dark horn-like accessories partly hidden in her hair. She wears an elaborate torn black-and-white gothic combat dress with layered ruffles, shredded fabric, exposed midriff, leather straps, metal thigh armor, mechanical gauntlets, and asymmetrical armored pieces. Her pose is dramatic and low-angle: she twists her body while raising one arm straight upward, gripping the hilt of an enormous vertical weapon suspended above her. The weapon is exactly one gigantic cathedral-like mechanical greatsword or lance, many times taller than her, with black gunmetal framework, brass joints, gears, pistons, pipes, ribs, and a glowing molten orange energy core running up the center; steam vents from both sides near the lower mechanism. The environment is a towering ruined interior with high arched ceilings, broken pillars, hanging chains, dark metal scaffolding, smoke, dust, and faint backlight through damaged windows. Use a narrow 9:16 composition, centered on the heroine and the weapon, with the weapon extending to the top edge and the character filling the lower half. Visual style: highly detailed Japanese dark fantasy concept art, painterly anime rendering, intricate linework, cinematic chiaroscuro, monochrome charcoal and steel palette with small orange highlights from the weapon core, dramatic perspective, windblown ribbons and hair, no text, no watermark.
