Use @[image ref] as the visual reference and opening keyframe. Create one continuous 15-second cinematic Japanese anime stealth-action video. Start from this scene: a lone swordsman on a rooftop above a futuristic megacity before dawn. Cold blue city lights, deep night sky, wet rooftop reflections, quiet wind, tense mission mood. His black coat moves in the wind. Keep design, silhouette, outfit, sword, colors, and mood consistent. Story: rooftop stillness → slow push-in → crouched stance → wire hook launch → high-speed glide between skyscrapers → diagonal descent along glass tower → window breach → spinning office entry → rapid elegant sword attacks against shadow enemies → aftermath stillness → final pose by shattered window. Tone: Cyber-noir, night-ops, silent infiltration, elegant but overwhelming. “Before dawn, everything is over.” Pacing: First 2s: quiet rooftop mood. Middle 10s: fast launch, glide, descent, breach, interior sword action. Final 3s: silence, floating dust and papers, mission-complete pose. Style: Feature-film-quality Japanese anime. Clean, polished, high-end animation. No grain, rough texture, or painterly dirt. Sharp linework, refined drawing, smooth gradients, cinematic lighting, crisp highlights. Dark colors with cool blue/silver accents. Animation: Smooth in-betweens, body weight, cloak physics, hair motion, wire tension, blade recoil, footwork, camera inertia, parallax, glass shards, paper flutter, dust, debris, clear impact timing. Camera: Slow push-in, low-angle launch, side-tracking glide, wide aerial city shots, whip pans, snap zooms, diagonal descent, breach framing, rapid interior cuts, final slow push-in. Readability: Sword and wire must stay clear. Use bright slash arcs, glowing blade trails, orange-white impact streaks, strong silhouettes, clean motion direction. Negative: No text, subtitles, logos, UI, arrows, labels, comedy, broken anatomy, gore, random scene changes, unreadable action, or character inconsistency.
