This prompt generates a polished vertical anime-style promotional poster for a sci-fi yuri mecha game, suitable for launch ads, store pages, and social media marketing.
A highly detailed vertical anime game launch poster in a dreamy post-apocalyptic sci-fi style, painted with cinematic lighting and a cool palette of lavender, indigo, silver, and pale pink. In the foreground, 2 teenage schoolgirls kneel face-to-face in shallow reflective water and rubble, creating an intimate emotional centerpiece. 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 serious, tender expression as she gently touches the other girl's face. The girl on the right has long silver-lilac hair, a damaged white-and-gray school uniform with a dark skirt, and a faint glowing halo-like ring behind her head, suggesting an android or supernatural identity. Their foreheads are close, with wind-blown hair and drifting pink flower petals around them. Behind them towers 1 massive broken humanoid mech, white and gray with scratched armor plates, an exposed inner frame, and a slumped ruined head, half-buried in debris. The background shows 2 heavily damaged building facades overgrown with vegetation, broken windows, and a bright cloudy sky with shafts of light, giving a melancholic yet hopeful mood. Add scattered wreckage in the lower corners, including 2 bent classroom chairs partially visible. Use a polished mobile game key art composition with dramatic depth, glossy reflections, soft bloom, volumetric light, and painterly detail. Include Korean promotional typography integrated into the poster: large vertical headline on the upper left reading 세계는 그날의 노래로 무너졌다, small English tagline on the upper left reading "The world collapsed in that song", small English text on the upper right reading "HOPE WILL FIND US", a large centered title near the bottom reading 스텔라 소라 with the romanized subtitle "STELLA SORA", a smaller genre line below reading "학원 × 메카닉 × 백합 서사 RPG", a large release date at the bottom center reading 2025.06.25, and "GRAND LAUNCH" beneath it. Along the bottom edge, show 4 platform and brand elements: 1 app icon with an anime girl portrait and a small search bar labeled 스텔라 소라, 1 App Store badge, 1 Google Play badge, and 1 Windows badge, plus a small publisher logo and copyright on the lower right for YOSTAR VERSE.
