{"id":"31548","prompt":"Create a high-detail vertical anime idol concert illustration of Nacha, a cheerful young female idol performing on a sparkling stage. She is shown full body from a slightly low angle, leaning playfully toward the viewer with a bright smile, holding a silver handheld microphone in her left hand. She has long voluminous twin-tail hair in silvery white with vivid orange streaks, orange-gold eyes, soft blush, glossy lips, orange nails, small earrings, and gold hair clips. Her outfit is a slightly unusual futuristic idol costume in white and silver: a strappy studded crop top with multiple buckles, a wide choker collar with square studs, star pendant necklace, off-shoulder transparent geometric vinyl sleeves, belt straps across the torso, a pleated mini skirt with one dark inner pleat, a side pouch, dangling silver chains and star charms, a translucent asymmetrical cape panel flowing behind her, and tall lace-up platform sandal boots with large ribbon bows. Count exactly 3 visible performers: 1 main foreground idol and 2 blurred backup idols in matching white stage outfits, one on the left background and one on the right background. The background is a dazzling live idol concert arena with purple, pink, blue, and white spotlights, starburst lens flares, bokeh particles, glitter confetti, a reflective glossy stage floor, and a cheering crowd implied by light dots. Use polished Japanese anime key visual style, extremely detailed costume rendering, luminous skin, flowing hair strands, dynamic motion, cinematic lighting, shallow depth of field, crisp focus on the main idol, glamorous and cute atmosphere, vertical 9:16 composition, no text, no watermark."}
