Moonlit Isekai Couple Cover

Create a square romantic Japanese isekai light novel cover illustration showing two characters standing very close together in the center of the frame: a tall silver-haired knight heroine and a modern high school boy. The heroine has {argument name="hair color" default="silver-white"} hair styled in an elaborate fantasy updo with dark floral ornaments, pale skin, and an ornate dark fantasy knight outfit with black armor pieces, leather straps, corset-like bodice, asymmetrical skirt details, thigh-high elements, gloves, chains, ribbons, and delicate magical accessories. The boy has messy black hair, wears a modern blue school-style jacket over a white shirt with loosened collar, dark straps and belt details, and a backpack-like silhouette, looking protective and shy as he stands shoulder-to-shoulder with her. Their faces are intentionally obscured by soft square censor-like blur blocks over the upper center, while their bodies and clothing remain highly detailed. Set them in a moonlit fantasy garden filled with icy blue foliage, hanging paper lanterns, drifting petals, glowing mist, crystal palace architecture in the background, and a large full moon behind them. Use a cool blue, silver, black, and lavender palette with luminous rim lighting, soft magical atmosphere, intricate anime-fantasy detail, dramatic painterly rendering, romantic light novel cover composition, and no visible title text, leaving subtle empty space near the top for a future title. Aspect ratio 1:1, highly polished, elegant, cinematic, ethereal, slightly chaotic decorative detail, no watermark.
