Liminal Japanese Novel Cover

Goal: Create an unsettling Japanese liminal-space novel cover for [book title], set in a sterile apartment-office corridor that feels infinite and quietly wrong.

Canvas: Vertical book-cover composition, 2:3 aspect ratio, cinematic photorealism with slight illustrated polish, cool blue-gray lighting, soft bloom, subtle film grain, deep perspective, high resolution.

Layout: Large Japanese title typography fills the top third in elegant black handwritten calligraphy, reading 「ヒューマン」 on the first line and 「インザループ」 on the second line. Between the two Japanese title lines, place small widely spaced roman letters reading “HUMAN IN THE LOOP” in pale pastel colors. The central vanishing point is a bright, endless 7F corridor seen through a doorway, with repeated ceiling lights and hallway frames receding into the distance. Foreground bottom center shows a lone person sitting on the floor in silhouette, hunched over and illuminated by a smartphone glow. Left side contains a stairwell rising upward; right side contains posters, documents, boxes, and plush mascots.

Subject details: The environment is a liminal institutional residential building: white walls, gray floor, fluorescent ceiling panels, stair railings, elevator-like corridor entrance, potted plants, posted notices, and signage. Add floor signs labeled “7F” above the doorway and on a left-side wall sign, with an arrow and small Japanese wayfinding text beneath it. The mood should be quiet, eerie, and emotionally lonely rather than overt horror.

Characters and objects: Include exactly 1 human figure: a young person with messy dark hair, wearing a loose pale shirt and dark pants, seated cross-legged on the floor, looking down at a glowing phone. Include exactly 7 visible physical sheep-like mascot plush toys named [mascot brand]: 3 on the stairwell at different heights, 2 on the right near cardboard boxes, 1 partial large plush in the bottom-right foreground, and 1 partial plush in the bottom-left foreground. The mascots are round, white, soft, with tiny black oval eyes, pink-and-yellow ears or horns, and a cute corporate-character look. Also include exactly 1 poster illustration of the same sheep mascot on the right wall.

Text content: The right wall poster should say “Pasto” at the top and include small Japanese text below, approximately 「やさしさは、つながり。」. A laptop or monitor on the floor at lower right displays Japanese interface text: large headline 「望月藍瑠の救出」, smaller line 「優先度：S」, and a rectangular button-like label 「詳細を確認」. Add a vertical Japanese tagline along the lower-left side in white and pink text: 「私があなたから引き出したものと、あなたが友人から引き出すものは、本質的に何が違うのか？」.

Visual style: Photorealistic cinematic cover art, cool desaturated palette with pastel pink and lavender accents, soft fluorescent glow, strong central perspective, shallow haze, clean but slightly uncanny corporate-residential atmosphere. Typography should feel refined and book-cover-like, with the Japanese title large and legible.

Constraints: Do not add extra humans. Do not add extra mascot plush toys beyond the 7 physical plush toys and 1 poster illustration. Keep all visible text integrated into the cover design. Avoid gore, monsters, weapons, or overt jump-scare imagery.
