การแสดงคอนเสิร์ตไอดอลอนิเมะแห่งอนาคต

A vertical anime idol concert illustration of [Nacha], a cheerful young female idol performing on a sparkling live stage. Full-body view 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. She wears an intricate futuristic idol costume in [white and silver]: a strappy studded crop top with buckles, a wide choker collar with square studs, a star pendant necklace, off-shoulder transparent geometric vinyl sleeves, torso belt straps, a pleated mini skirt with a dark inner pleat, a side pouch, dangling silver chains and star charms, a translucent asymmetrical flowing cape panel, and tall lace-up platform sandal boots with large ribbon bows. Count exactly three visible performers: one crisp foreground idol, and two softly blurred backup idols in matching stage outfits in the left and right background. The setting is a dazzling concert arena with purple, pink, blue, and white spotlights, starburst lens flares, glowing bokeh, drifting glitter confetti, a glossy reflective stage floor, and stadium light dots indicating a cheering crowd. Japanese anime key visual style, luminous skin, dynamic motion, shallow depth of field, cinematic stage lighting, no text, no watermark.
