Anime Sci-Fi Mecha Game Launch Poster

A vertical anime mobile game launch poster in a dreamy post-apocalyptic sci-fi style, featuring cinematic lighting and a cool palette of lavender, indigo, silver, and pale pink. In the foreground, two teenage schoolgirls kneel face-to-face in shallow reflective water and concrete rubble. The girl on the left has very long flowing dark violet hair, a navy sailor-style school uniform with a pleated skirt, black knee socks, and a tender, solemn expression as she cups the other girl's cheek. The girl on the right has long silver-lilac hair, a damaged white-and-gray school uniform, and a faint glowing halo ring behind her head. Their foreheads touch gently amidst wind-blown hair and drifting pink flower petals. Towering behind them is a massive ruined humanoid mecha with scratched white-and-gray armor plates, an exposed mechanical frame, and a slumped damaged head half-submerged in debris. The background shows ruined overgrown city building facades, shattered glass, and a luminous cloudy sky with volumetric god rays. Lower corners include scattered wreckage with bent classroom chairs in the water.
