Copertina per Light Novel Anime Fantasy

An anime-style light novel cover illustration. In the foreground, a beautiful young woman with [long silver hair] and large blue eyes wears an intricate white lace dress and a silver floral tiara with white roses, reaching her hand forward with a gentle, longing smile. Behind her, a young man with black hair wearing an [ornate black coat with red accents and silver chains] stands facing away, glancing back over his shoulder melancholically. They stand on a balcony overlooking a [gothic fantasy castle city at dusk], with white rose petals drifting in the wind. Prominent, elegant Japanese typography is integrated across the cover: the large main title reads "[善人をやめた悪役貴公子は、白薔薇の聖女を遠ざける]" in stylized fonts with gold and blue gradients; a vertical catchphrase on the left reads "[世界を守るため、俺はもっと悪になる。]"; a vertical catchphrase on the right reads "世界を敵に回しても、あなたの隣にいたい。"; and small author credits and a publisher logo appear at the bottom. Dramatic and romantic atmosphere with dynamic dusk lighting.
