โปสเตอร์เปิดตัวเกมอนิเมะหุ่นยนต์

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 {argument name="headline text" default="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 {argument name="game title" default="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 {argument name="release date" default="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 {argument name="search label" default="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 {argument name="publisher name" default="YOSTAR VERSE"}.
