A stunning upper-body illustration of an ethereal Korean girl against a blazing night-time cityscape. She is captured in a dynamic 3/4 angle, striking a powerful stance as she unsheathes a gleaming mechanical longsword with both hands. She has porcelain-smooth, luminous skin, delicate and sharply contoured facial features, and captivating ice-blue eyes that gaze forward with serene confidence. Her long, waist-length platinum-silver hair flows dramatically, the slightly curled tips and bangs gently tousled by an unseen breeze, adorned with a single crystalline snowflake-shaped hair clip and matching ice-crystal earrings. Her slender, graceful figure is clad in a sleek technological white jacket over black tactical armor plates, secured with a bold crimson waist guard. Swirling, razor-sharp frost blades and arcs of freezing energy emanate from her sword, embodying her ice-attribute magic. The night sky behind her is alive with distant city lights and flickering flames, casting dramatic highlights across her armor and hair. The image maintains crisp, clean linework, gentle color palette, and glossy, expressive eyes typical of refined Korean manhwa illustration.
