Armored hero landing on a ruined city rooftop

15s vertical 9:16, 24fps, dark fantasy hero transformation, cinematic realistic tone, high contrast, smooth steady camera, no frame jump, no glitches, natural emotional rhythm. 0-3s Low-angle wide shot, stormy desolate cityscape, overcast dark sky, distant lightning flickers. A tough East Asian young man lands gently on rooftop ruins, having just escaped danger, raising light dust around him, scattered documents and debris lie on the rooftop. 3-6s Slow push-in close-up, the man is dust-covered, exhausted, wearing tattered worn clothes. He breathes steadily, eyes firm, holding a glowing blue crystal in his palm, soft crystal light reflecting on his skin, floating dust drifts gently around him. 6-9s He grips the crystal tightly, calm and focused, bright blue energy spreads along his arms. A soft white light pillar descends from the sky, enveloping his whole body. Airflow blows scattered papers flying, white feathers drift down slowly, his tattered clothes fade under energy radiation to trigger the hero transformation. 9-12s Camera pulls back slowly, golden-white mecha armor covers his body layer by layer in smooth sequence, shoulder and chest armor take shape one after another. Giant luminous wings condense from light particles behind him, feathers flutter slightly, glowing lines flicker on the mecha surface naturally. 12-14s Transformation completed, the young man in full golden-white mecha hovers slowly above the rooftop with huge wings spread out. Surrounding feather particles float gently, the light pillar fades away gradually. He lifts his head with a firm and determined gaze, ready to protect the city. 14-15s Low-angle dynamic tracking shot, mecha's thrusters ignite, soft blue-white light bursts from its back. It lunges forward smoothly, flying towards the stormy sky, wings cutting through the wind. The final frame captures the hero's powerful takeoff moment, full of imposing momentum. Optimizations: High motion blur, shallow depth of field, crushed blacks, glowing highlights on mecha and light, natural breathing and expressions, smooth flight movement, no visual distortion.
