Create a high-quality 4K vertical 9:16 anime-style fantasy illustration. Theme: Tanabata, wishes, a sacred summer night, and a magical Milky Way made of flying tanzaku wish papers. Scene: A quiet Shinto shrine courtyard at night after a Tanabata festival. The atmosphere is calm, sacred, dreamy, and emotional. Stone pavement, bamboo branches with Tanabata decorations, softly glowing paper lanterns, a torii gate silhouette, and the faint outline of a shrine building are visible in the background. Composition: Use a dramatic vertical composition. Place a young boy and a young girl near the bottom of the image, seen from behind or slightly from behind. They are holding hands and looking up at the sky. Make them small enough so the vast night sky feels overwhelming and magical. Main visual concept: Countless colorful tanzaku wish papers rise from the bamboo decorations and float upward into the night sky. The papers swirl gracefully through the air, forming a luminous river of wishes that gradually becomes the Milky Way. Some tanzaku slowly transform into tiny glowing stars and stardust. The flow of tanzaku should guide the viewer’s eye from the shrine ground at the bottom to the vast starry sky at the top. Characters: The boy wears a dark navy or deep indigo yukata, simple and elegant. The girl wears a pale white, light blue, or soft lavender yukata, delicate and summery. They should feel innocent and pure, not overly romantic. Their hand-holding should look natural and gentle. Their faces do not need to be visible clearly; focus on their silhouettes, posture, and the emotion of looking up together at a miracle. Tanzaku details: Use soft pastel colors such as pale pink, lavender, sky blue, white, soft gold, and pale teal. The tanzaku may have faint calligraphy-like marks, but no readable text, no clear letters, no actual words. The papers should glow softly, like they are carrying people’s wishes into the sky. Lighting: Soft lantern light from below, cool moonlight from above, and gentle glowing light from the tanzaku. Add sparkling particles, floating dust, and subtle mist for a magical atmosphere. The scene should feel like a quiet miracle happening in a real shrine. Mood: Fantasy, sacred, emotional, nostalgic, beautiful, serene, poetic, cinematic, summer night, wishful, magical realism. Style: High-quality anime illustration, detailed background, beautiful night sky, cinematic lighting, soft painterly coloring, delicate line art, rich atmosphere, polished key visual quality.

Avoid: Do not make it look like a battle scene. Do not add fireworks. Do not add modern city buildings. Do not make the characters too large. Do not show readable text or words on the tanzaku. Do not add logos, captions, watermarks, or typography. Avoid distorted hands, extra fingers, unnatural arms, messy anatomy, broken faces, overexposed lighting, cluttered composition, and AI-like artifacts.
