Generate a 15-second, 16:9 landscape Japanese anime opening sequence. Use the visual language of a modern Japanese anime opening with a retro printed urban atmosphere. Combine 2D hand-drawn animation, cel shading, dynamic key animation, and graphic-design aesthetics. Preserve a tactile paper-grain surface, halftone dots, and retro manga print-registration misalignment caused by layered color printing.

This should not be a character showcase PV. It should be a strongly rhythmic character montage. Center the sequence around one cool, retro urban girl, maintaining the exact same face throughout the entire video: jet-black bobbed hair with straight bangs and sharply layered ends, cool dark almond-shaped eyes, matte red lips, a signature beauty mark beneath the lower lip, a black tank top with heart-shaped patches, layered beaded necklaces, and a padlock pendant. Keep her facial structure and overall presence consistent in every shot.

Use a three-color visual system dominated by black, lake blue, and scarlet red, with milk-white accents. Build her personality through large areas of solid color, abstract urban silhouettes, geometric color blocks, shadows, manga-style compositions, and graphic visual symbols.

Use the rapid editing language commonly found in Japanese anime openings, including extreme close-ups of the eyes, red lips, padlock pendant, fingertips, and hair ends; tilted compositions; low-angle perspectives; sudden push-ins; frame slicing; and dynamic visual recombination. The editing rhythm may be freely arranged by the model according to the electronic beat.

Add halftone patterns, ink lines, drifting heart-shaped stickers, halos and light spots, film grain, color-registration offsets, floating flat graphic text, and geometric symbols as part of the visual language.

Emphasize a cool, distant, retro-urban loneliness with a mysterious, alluring quality, combined with a touch of City-pop nostalgia and a sense of fate. The result should feel like the official opening sequence of a Japanese television anime, not a game promotional CG trailer.

Avoid complex fantasy environments, realistic locations, battle demonstrations, 3D rendering, and any drift in the character’s facial features.
