ساموراي حامل الراية تحت قمر عملاق

Vertical anime key visual illustration in intense sapphire-blue moonlight. A lone young samurai stands seen from behind on a grassy hilltop in the lower center, holding a tall pole with a large tattered [deep-blue battle flag] bearing a [pale circular crest emblem], billowing dramatically to the right. He wears a dark blue wind-swept samurai outfit with a heroic silhouette. Below lies a vast luminous valley with distant mountains, glowing energy river lines, scattered city-like lights, and floating blue motes. Dominating the upper sky, an enormous full moon displays the darker blue silhouette of [the Japanese archipelago] across its cratered surface. The deep navy night sky is densely filled with stars and [nine bright cyan shooting stars] streaking diagonally downward. Volumetric glowing clouds frame the horizon, with electric-blue highlights tracing the foreground grass and rocks. Dynamic wind, high contrast, radiant bloom, cinematic anime concept art, no text, no watermark.
