Create a 16:9 cinematic anime key visual featuring a clearly adult young female mecha pilot. Her pale skin is marked with soot and salt spray, her sharp amber eyes reflect glowing HUD targeting reticles, and her waist-length ash-white hair is tied in a high ponytail whipping through the sea wind. Matte gunmetal exoskeleton armor covers her shoulders, forearms, and shins, with exposed hydraulic pistons at the joints and glowing cyan coolant lines across the chest rig. An oversized oil-stained hangar jacket hangs ruggedly from one shoulder without sexualized framing, a massive rail cannon rests on her right shoulder, and dog tags plus a frayed red ribbon hang at her collar. She stands slightly off-center to the left on the rusted edge of a tilted steel platform extending over dark ocean water. Her weight rests on one leg, her left hand grips the cannon strap, and her head turns slightly toward the camera with a quiet, defiant stare. Steam vents from her back thrusters while her ponytail and jacket stream sideways in the salt wind. The background is a vast derelict sea city at dusk: colossal unknown megastructures rise from the ocean in staggered silhouettes, bone-white monolithic towers merge with barnacled steel, cyclopean ring structures tilt at broken angles, rusted skeletal gantries are threaded with dead cables, dark waves surge between pylons, and half-sunken shipwrecks lie at their bases. Thick sea fog clings to the lower structures while the upper towers pierce a bruised sky, with scattered faint lights blinking high above like distant eyes. Use moody low-key lighting: cold teal ambient light from the overcast sky, warm amber sodium glow leaking from a distant structure on camera-right, hard backlight from a low sun behind the towers carving her silhouette, volumetric rays through sea mist, and wet specular highlights on the armor. Use a 35mm anamorphic widescreen lens, slight low-angle view looking past her shoulder toward the structures, medium-wide composition, shallow depth of field with foreground rust softly blurred, horizontal lens flares, fine atmospheric haze, painterly digital illustration with crisp line art, desaturated teal, bone-white, and rust palette with small warm accent lights, film grain, and high-contrast editorial poster texture. Avoid underage appearance, nudity, explicit sexual posing, copied franchise designs, real logos, malformed armor, unreadable HUD clutter, broken weapon geometry, extra watermarks, and low-resolution artifacts.
