Epic anime battle scene on a floating city above the clouds. A young samurai with glowing katana clashes against a cybernetic warrior, energy sparks and shockwaves lighting up the sky. The camera sweeps dynamically in anime-style tracking shots, switching between wide panoramic views and intense close-ups of expressive faces. Vibrant colors, dramatic speed lines, exaggerated motion blur, and cinematic sakuga animation quality. The background sky glows with sunset hues, clouds breaking apart from the battle impact. Ultra-detailed textures, shining neon reflections, smooth 2D anime style combined with 3D depth. Feels like a Makoto Shinkai x ufotable crossover anime movie trailer.
