Fantasy Villainess Novel Cover

Goal: Create a richly detailed Japanese fantasy light-novel cover illustration for a royal villainess romance story, with an ornate ensemble cast arranged around a dramatic central heroine and a fairy-tale castle backdrop. Canvas: Vertical book-cover composition, 2:3 aspect ratio, polished anime illustration style, extremely detailed, luminous jewel tones, elegant shoujo fantasy atmosphere, no modern objects. Layout: Use a dense poster-like composition with exactly 9 visible characters layered in depth around the page. The central lower-right figure is the main heroine, surrounded by noble men and women in a royal court setting. Place a white castle with tall blue spires in the upper center background, framed by a grand arched window or palace arch. Add an ornate gold filigree border around all edges. Scatter glowing blue-purple crystal shards, pink rose petals, and magical sparkles throughout the image. Place the main Japanese title across the lower-left to center area, partially overlapping the characters, with a small subtitle beneath it. Characters: Include exactly 9 characters: 1) central heroine, a glamorous black-haired noblewoman in a dark emerald and black off-shoulder gown with lace, gold chains, emerald jewelry, jeweled hair ornaments, and a poised villainess aura; 2) central white-haired nobleman in a black military-style coat with gold trim, chains, brooches, and a serious romantic-lead presence; 3) top-left red-haired armored knight in dark red and silver armor with a fur mantle and jeweled shoulder ornament; 4) top-right blond prince in a navy-blue high-collared uniform with elaborate gold chains and epaulets; 5) left-side silver-haired lady in a dark navy noble outfit, elegant and reserved; 6) right-side blonde princess in a pale blue frilled gown with floral hair accessories; 7) mid-right dark-haired nobleman in a dark suit with red tie, partially turned away; 8) bottom-left black-haired young nobleman in a black suit with gold trim and a red tie, looking intense; 9) bottom-right blond nobleman in a white-and-gold ceremonial uniform with red sash, gloved hand near his face. Keep all faces beautiful anime-style and expressive. Text content: Add the large Japanese title {argument name="headline text" default="悪役令嬢は 今世こそ 幸せになりたい"} in elegant calligraphic typography, with the first and last major words in deep red and purple gradients and the smaller connecting words in black. Add the small subtitle {argument name="subtitle text" default="断罪される人生なんて、もうこりごりですから。"} centered below the title in delicate black Japanese type. Decorative flourishes should surround the text like a real fantasy novel cover. Visual style: Highly polished romantic anime cover art, intricate linework, glossy highlights, sparkling magical crystals, purple roses at the bottom, lavish gold ornaments, cinematic lighting, soft sky-blue and violet background, dramatic depth, luxurious royal-fantasy mood. Use {argument name="main heroine hair color" default="long glossy black"} hair for the heroine, {argument name="central male hair color" default="silver white"} hair for the main male lead, and {argument name="overall color palette" default="royal navy, violet, emerald, gold, and icy blue"} as the dominant palette. Constraints: Make it look like a finished Japanese fantasy romance novel cover, not a character sheet. Preserve exactly 9 characters, one castle, one ornate border, many crystals, many rose petals, and several purple roses at the bottom. Do not add logos, watermarks, author names, barcode, or extra text beyond the title and subtitle.
