Japanisches Liminales Psychothriller-Buchcover

Vertical book-cover composition in a 2:3 aspect ratio, cinematic photorealism with slight illustrated polish, depicting an unsettling Japanese liminal-space novel cover for [Human in the Loop]. Setting: A sterile, infinite apartment-office corridor inside an institutional residential building with white walls, gray flooring, fluorescent ceiling panels, stair railings, elevator doorway, potted plants, posted notices, and wayfinding signage labeled “7F” with an arrow above the doorway and on a left wall plaque. Composition & Lighting: Strong one-point central vanishing point looking down a bright, endless 7F hallway receding into the distance. Cool blue-gray palette with pastel pink and lavender accents, soft fluorescent bloom, shallow atmospheric haze, and subtle film grain. In the foreground bottom center, a single human figure sits hunched on the floor in silhouette, illuminated by the glow of a smartphone. A stairwell rises on the left; cardboard boxes, posters, and documents line the right wall. Characters & Objects: Exactly 1 person (young, messy dark hair, loose pale shirt, dark pants, seated cross-legged looking at a phone). Exactly 7 visible physical sheep-like plush mascots named [Pasto] (round, white, soft, tiny black oval eyes, cute pink-and-yellow horns): 3 placed on the stairs at varying heights, 2 near boxes on the right, 1 cropped plush in the bottom-right foreground, and 1 cropped plush in the bottom-left foreground. On the floor at the lower right, an open laptop or monitor shows a digital interface reading 「望月藍瑠の救出」, subline 「優先度：S」, and a button labeled 「詳細を確認」. Typography & Graphic Text: Across the top third, prominent elegant Japanese calligraphy reads 「ヒューマン」 on line one and 「インザループ」 on line two. Between these lines, small spaced roman letters read “HUMAN IN THE LOOP” in pale pastel. On the right wall, exactly 1 poster displays the sheep mascot, titled “Pasto” with subtext 「やさしさは、つながり。」. Along the lower-left edge, a vertical Japanese tagline in white and pink reads: 「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？」. Constraints: Exactly 1 human, exactly 7 plush toys, exactly 1 poster mascot. No overt monsters, gore, or weapons.
