Create a dramatic vertical anime mobile game advertisement poster set in a ruined sci-fi city at dusk. In the foreground, show 2 teenage schoolgirls inside the broken cockpit of a crashed futuristic vehicle: one girl has long straight black hair and kneels on the left, the other has short blue bobbed hair with a small flower hairpin and sits on the right. They are embracing tightly with frightened, vulnerable expressions, holding hands at the center of the image. Both wear torn Japanese sailor school uniforms with white tops, navy collars, red neckerchiefs, and blue pleated skirts; add visible bandages, scrapes, and dirt on their arms and legs. The cockpit around them is heavily damaged, with exposed wiring, glowing orange and cyan control panels, torn metal, and a partially open canopy framing the pair. In the midground and background, depict a devastated urban battlefield with collapsed buildings, smoke, sparks, rubble, and scattered fires. In the sky, paint a huge swirling blue-white vortex or portal in the upper right, sending down a bright beam of light; add flying debris and a few meteor-like streaks crossing stormy clouds. Use highly polished anime key art styling, cinematic lighting, rich blue and orange contrast, glossy rendering, detailed mechanical textures, emotional storytelling, and a premium Korean gacha game promotional feel. Overlay bold Korean ad text integrated into the composition: at the top, large headline '{argument name="headline text" default="글로벌 런칭"}' with a smaller subtitle below '{argument name="top subtitle" default="지금 다운로드 가능"}'; near the bottom center, a large ornate fantasy title '{argument name="game title" default="하늘의 연가"}' with a smaller subtitle beneath '{argument name="game subtitle" default="세카이의 끝"}'; below that, another bold call to action '{argument name="bottom call to action" default="지금 다운로드 가능"}'. Add a small rounded tag line at the very bottom reading '세카이 계 · 학원물 · 메카닉 · GL'. Make it look like an official app install poster, ultra-detailed, high contrast, emotional, dynamic, and optimized for a smartphone portrait ad. Copy prompt
