Guerrière Gothique à l'Épée Mécanique

Tall vertical dark-fantasy anime concept art of [an unnamed silver-haired warrior girl] inside a ruined gothic cathedral fused with industrial machinery. Composition: extreme low-angle heroic portrait, with the young woman filling the lower two-thirds of the frame, twisting upward while holding a colossal mechanical greatsword vertically above her head, its blade pointing toward the top edge like a spire. Weapon details: single oversized steampunk greatsword with an illuminated orange energy core running down the center, exposed pistons, layered metal ribs, circular gears, pipes, bolts, and vents expelling white steam on both sides. Character appearance: [long silver-white hair] streaming wildly in dynamic windblown strands, pale skin, sharp sleepy eyes, and a calm, melancholic expression. Attire: tattered black-and-white gothic battle dress with torn ruffles, dark lace, leather straps, asymmetrical armored sleeves, thigh armor plates, belts, and metal gauntlets, accented by long white fabric ribbons flowing around her figure. Setting & Atmosphere: towering shadowy cathedral interior with fractured arches, dangling chains, scaffolding-like industrial ribs, haze, dust particles, and faint light breaking through damaged stained glass. Lighting & Palette: dramatic chiaroscuro with muted charcoal black, ash gray, bone white, tarnished steel, and vibrant copper-orange glow from the weapon core. Highly detailed painterly Japanese anime art style, intricate linework, vertical 9:16 composition, single subject focus, no text.
