Portada de Novela de Terror Urbano Japonés

A dark psychological horror novel cover illustration in a cinematic, gritty digital-painting style. A wide, ominous composite scene set in a decaying modern Japanese urban environment blends a crowded commuter train interior on the left and a late-night office on the right. In the exact center foreground, a ghostly female apparition stands seen from behind, her long dark hair messy and damp, her head obscured by a solid black rectangular void. Her body and hair merge into black stains and shadow, dividing the two spaces. On the left, the train car interior shows four commuters: two standing businessmen near hanging straps, one seated woman in muted office wear with a blurred face, and a distant passenger near the door, amidst grimy metal poles, scratched windows, and a claustrophobic perspective. In the bottom-left foreground sits a large cracked white flowerpot holding a withered dead plant. On the right, a bleak office interior shows three workers at desks under harsh fluorescent lights among computer monitors, paperwork, and glass partitions; in the right foreground, a cropped salaryman stands from chest to thigh in a wrinkled white shirt and loosened tie, head cut off by the upper frame. Black cracks, grime, ink-like tendrils, and water stains spread across the surfaces. Cold palette of blue-gray, charcoal, dirty white, and desaturated brown with harsh overhead fluorescent lighting and deep shadows. Centered over the figure, overlay large distressed, eroded white Japanese title text: "[隙間、そのもの]", with smaller cracked white subtitle text beneath: "[第１日：月曜日]", styled in horror typography.
