Character anime poster street cool-tone

Create a dark vertical anime street art poster, with standing in the lower half of the center, facing forward with a cold expression. He has messy hair, bangs covering his forehead, pale skin, one eye glowing ice blue emerging from the shadows, wearing a high-collar black tactical coat or cloak with angular straps and a wet sheen. Behind him, fill the entire background with a giant shadowy face or demon mask silhouette, revealing only two narrow cyan-white glowing eyes at the upper middle, looming over him. Use a rough urban decay wall texture background, including cracked concrete, heavy black ink stains, mottled paint, red and cyan/teal glitch blocks, horizontal digital smearing artifacts, scratches, splatters, drips, and torn poster layers. Directly above the character in the center, add a vertical white graffiti/calligraphy rune, abstract and illegible, resembling Japanese brush strokes. The composition should remain symmetrical and cinematic, portrait ratio 2:3, high contrast, dominated by black and charcoal gray with accents of intense blood red and teal, strong top/back lighting on the hair, deep shadows on the face and coat, creating a cyberpunk glitch horror atmosphere, combining painterly anime illustration with street graffiti and digital distortion effects. Except for the abstract rune, do not include any readable text, no watermark, no extra characters.
