动漫轻小说封面插画

A highly detailed anime-style light novel cover illustration. In the foreground, a beautiful young woman with {argument name="female hair color" default="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 {argument name="male outfit" default="ornate black coat with red accents and silver chains"} stands facing away, looking back over his shoulder melancholically. They are on a balcony overlooking a {argument name="background setting" default="gothic fantasy castle city at dusk"}, with white petals scattering in the wind. The image features prominent, elegant Japanese typography. The large main title reads "{argument name="main title" default="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 "{argument name="left catchphrase" default="世界を守るため、俺はもっと悪になる。"}" and another on the right reads "世界を敵に回しても、あなたの隣にいたい。". Additional text at the bottom includes author credits and a publisher logo. The overall mood is dramatic and romantic with dynamic lighting.
