Goal: Create a polished anime concept art character sheet for {argument name="character name" default="BYAKUYA"}, a blind samurai and keeper of a jade staff, mixing cyberpunk rooftop atmosphere with traditional ronin design.
Canvas: Vertical poster-style character sheet on an off-white textured paper background, approximately 2:3 aspect ratio. Use clean editorial spacing with dark purple ink accents, thin divider lines, and a premium game art book presentation.
Layout: Left half dominated by a large dynamic full-body action illustration of the samurai leaping or crouching forward on a rain-slick city rooftop at night, neon skyscrapers behind him, purple light reflecting on wet concrete. Top-left has a huge rough brushstroke title reading {argument name="headline text" default="BYAKUYA"}, with the subtitle “BLIND SAMURAI / KEEPER OF THE JADE STAFF” beneath it. Right half contains a “TURNAROUND” section with exactly 3 standing character views labeled FRONT, SIDE, and BACK. Below that is a “WEAPON” section showing exactly 1 horizontal jade-ended staff. Below that is a “COLOR PALETTE” section with exactly 4 rough paint swatches labeled JADE, INDIGO, MIDNIGHT, and ANTIQUE GOLD. Bottom-left has a “DETAILS” section with exactly 4 close-up panels: conical hat and shadowed blindfolded face, armored mechanical glove, green sleeve with purple markings, and heavy strapped boot. Bottom-right contains exactly 1 cinematic wide panel of the character standing on a rainy rooftop holding the vertical glowing staff against a purple neon skyline.
Character details: The samurai is a mature male with tan skin, a stern shadowed face, a dark blindfold or obscured eyes under a wide black kasa hat decorated with subtle gold floral motifs. Long white hair streams from beneath the hat. He wears a loose oversized {argument name="jacket color" default="jade green"} hooded jacket with purple straps and sash ties, dark teal baggy trousers, armored bracers, a black-and-gold mechanical glove, strapped black boots with purple and antique-gold hardware, and a turtle-shell-like brown backpack visible in the back view. His expression and posture should feel calm, dangerous, and disciplined.
Weapon: A long black staff with translucent glowing jade-green crystalline caps at both ends, brass-gold collars, and subtle internal light. In the action pose, the staff should cut diagonally through the composition with strong perspective.
Visual style: High-detail cinematic anime illustration, sharp inked linework, painterly texture, dramatic purple neon rim lighting, rain droplets, glossy wet reflections, splattered indigo paint behind the main figure, cyberpunk city lights, concept-art sheet clarity, moody but readable. Color emphasis should match {argument name="primary palette" default="jade green, deep indigo, midnight blue, antique gold, and neon purple"}.
Text content: Include the Japanese title “サイレントブレード” above the spaced English title “S I L E N T B L A D E.” Keep all visible labels crisp and legible: TURNAROUND, FRONT, SIDE, BACK, WEAPON, COLOR PALETTE, JADE, INDIGO, MIDNIGHT, ANTIQUE GOLD, DETAILS.
Constraints: Use exactly the listed sections and counts: 3 turnaround poses, 1 weapon render, 4 color swatches, 4 detail panels, and 1 bottom cinematic panel. Do not add extra characters, logos, watermarks, UI elements, or unrelated text.
