Knielende blauwgepantserde ridder

A dramatic vertical fantasy anime illustration of a kneeling female knight in side profile, centered slightly right, holding a massive upright greatsword with both armored hands as if in prayer or solemn resolve. She has very long flowing hair in {argument name="hair color" default="silver-white"}, smooth and luminous, cascading down her back almost to the ground. Her face is mostly hidden by the side angle and lowered head, giving a quiet, introspective mood. She wears sleek reflective metallic armor in {argument name="armor color" default="deep cobalt blue"}, highly polished with glossy highlights, including sculpted shoulder plates, long armored gauntlets, a fitted breastplate with exposed side torso cutouts, a segmented waist guard, and thigh-high armored boots. The lower outfit is a short pleated armored skirt in matching blue metal. Her physique is slim and elegant, with a stylized anime beauty aesthetic. The sword is tall, dark steel with a broad blade and ornate crossguard, extending vertically from the ground near the left side of the image to above the frame. The pose is one-knee kneeling, torso upright, head slightly bowed toward the sword, conveying reverence, mourning, or determination. Set in a ruined stone corridor or ancient city passage with towering blurred walls on both sides, soft fog, floating dust motes, and a cold blue-white backlight pouring from above and behind, creating rim light around her hair and armor. Add subtle debris near the ground, cinematic depth of field, high contrast reflections, ethereal atmosphere, ultra-detailed surfaces, polished metal shading, and a premium heroic dark-fantasy mood in the style of {argument name="illustration style" default="high-detail cinematic anime key art"}.
