Art style: манга 4.
Interior sel penjara yang sempit dan gelap pada malam hari. Protagonis berbaring di tempat tidur besi tingkat, matanya terbuka lebar menatap langit-langit beton. Cahaya bulan yang pucat masuk melalui jendela berjeruji kecil, membentuk pola garis-garis di dinding yang lembap. Suasana melankolis dengan palet warna biru gelap dan hitam pekat.

FINAL STYLE ENFORCEMENT (this is the authoritative rendering directive — it overrides any style wording elsewhere in the prompt):
Render this image entirely in "манга 4" style. Match the lighting grammar, material response, colour science, level of realism / stylisation, line weight, and shading model typical of "манга 4".
Keep the subject, composition, camera angle, lighting direction, and colour palette from the description above — but EVERY surface, skin, fabric, material, and environmental element must be rendered in the "манга 4" idiom, not in any other medium.
