Poster Film Anime Blockbuster Sky Fantasy

A breathtaking Japanese anime movie poster in the style of a blockbuster theatrical key visual, ultra-detailed and emotionally grand, with a delicate luminous sky reminiscent of prestige modern anime cinema. The scene shows 2 characters from behind on a flower-covered cliff overlooking a glowing coastal fantasy city at sunset and twilight: a teenage boy in a dark school uniform with a loosened tie and windblown short dark hair stands on the left, and a teenage girl in a long flowing pale dress with very long silver-white hair stands on the right. Both face the horizon in awe. Above them, an enormous celestial sky fills most of the composition, painted with vivid deep blue, indigo, violet, magenta, and gold clouds, a brilliant comet-like meteor streak slashing diagonally from upper center toward the horizon, scattered stars, sparkling particles, and a glowing circular magic-like ring constellation in the upper right sky. The sea and city below shimmer with reflected light, with slender fantasy skyscrapers and towers rising from the coastline and a radiant sunlit gap at the center horizon. Foreground flowers are saturated blue and purple with glowing highlights, and white-pink petals drift through the air. Use dramatic rim light, cinematic backlighting, lens-glow sparkle effects, highly polished anime rendering, crisp linework, atmospheric depth, and a vertical poster composition. Include Japanese poster typography integrated into the design: giant embossed gold headline text across the top reading {argument name="top headline text" default="Box office revenue exceeds 10 billion yen."}, a gold subheadline block at upper left reading {argument name="subheadline text" default="大ヒット上映中"}, a vertical white tagline on the upper right reading {argument name="tagline text" default="あの日、君と見上げた空が、世界を変える。"}, and a very large glowing white-lavender Japanese film title at the bottom center reading {argument name="movie title" default="星屑の約束"}. Beneath the title, add small elegant romanized subtitle text reading {argument name="romanized subtitle" default="Hoshikuzu no Yakusoku"}, plus dense small production credits, cast lines, website text, release-copy lines, and cinema format logos along the bottom edge in authentic Japanese movie-poster layout. Add 2 gold laurel emblems flanking the top headline, one on the left and one on the right. Make it feel like a fictional anime film that earned 10 billion yen at the box office, sweeping, romantic, bittersweet, magical, and destined to make audiences cry.
