Couverture de Light Novel Isekai

A square romantic Japanese isekai light novel cover illustration featuring two characters standing very close together in the center. On one side stands a tall fantasy knight heroine with [silver-white] hair styled in an elaborate fantasy updo with dark floral ornaments, pale skin, wearing an ornate dark fantasy knight outfit with black armor pieces, leather straps, a corset bodice, asymmetrical skirt, thigh-high details, gloves, chains, ribbons, and magical accessories. Standing shoulder-to-shoulder with her is a shy modern high school boy with messy black hair, wearing a blue school jacket over an unbuttoned white collar shirt, straps, belts, and a backpack silhouette. Soft square censor-like blur blocks obscure their faces in the upper center, leaving their intricate bodies and clothing fully visible. Setting: a moonlit fantasy garden with icy blue foliage, glowing paper lanterns, floating petals, luminous mist, crystal palace architecture, and a massive glowing full moon behind them. Palette of cool blue, silver, black, and lavender with bright rim lighting. Romantic light novel composition, leaving negative space near the top for a title, painterly anime style, highly detailed, no text or watermark.
