A polished black-and-white manga tankōbon cover for a detective thriller called "Null Case". Portrait format, full-bleed illustration. A tall, sharp-featured detective in a long coat stands in three-quarter profile, arms crossed, cigarette smoke curling from his lips tracing an abstract spiral. Background: dense rain rendered as fine diagonal parallel lines over a city skyline of angular ink-blocked buildings. Top of cover: bold stylized Japanese-esque title block with large brushstroke text reading "NULL CASE" and subtitle "Vol. 3" in smaller block letters. Author name area bottom-right: "by Ryo Shindō" in smaller print. Cover border: double-line rule with small decorative crosshatch corners. Character shading: high-contrast ink with selective screentone on coat and background. No color — pure black, white, and grey screentone. The detective's eyes: thin, calculating, catching a single catch-light each.
