Samurai and Battle Flag in Moonlight AI Image Prompt

Create a vertical cinematic anime fantasy illustration in intense sapphire-blue moonlight. A lone young samurai stands from behind on a grassy hilltop in the lower center, holding a tall pole with a large tattered deep-blue battle flag blowing dramatically to the right; the flag bears a pale circular crest emblem. He wears a dark blue samurai-inspired outfit with wind-swept cloth and a heroic silhouette. The landscape below is a vast luminous valley with distant mountains, rivers or glowing energy lines, scattered city-like lights, and sparkling blue particles. Above him, an enormous full moon dominates the sky, almost filling the upper half of the image, with the islands of Japan visibly formed as darker blue shapes across the moon’s surface. The night sky is packed with stars and exactly 9 bright blue shooting stars/meteor streaks crossing diagonally downward. Add layered glowing clouds around the horizon and moon, electric-blue highlights on grass and rocks in the foreground, and a sense of epic national myth and hope. Use ultra-detailed anime key visual style, high contrast, radiant bloom, volumetric clouds, crisp moon craters, dynamic wind, deep navy shadows, luminous cyan accents, vertical 9:16 composition, no text, no watermark.
