Palco Futuristico per Concerto Idol Anime

An anime idol concert scene on a futuristic holographic stage, featuring exactly three young female virtual pop idols performing synchronized choreography with one arm raised straight upward and index finger pointing to the sky. The center idol stands slightly forward with [long pastel pink twin tails], soft pink eyes, and a confident smile. The left idol has [short blonde bob hair] and a warm smile. The right idol has [short black hair with vivid blue highlights], bangs partly obscuring one eye, and a cool expression. All three wear matching [dark navy starry holographic mini dresses] with glossy corset bodices, sweetheart necklines, sheer long black sleeves, ruffled short skirts, constellation star patterns, star chest ornaments, black chokers, wrist cuffs, and thigh-high dark stockings with star accents. Setting is a sci-fi concert arena with glowing blue crystalline arches, metallic structures, sweeping white laser beams, misty cyan holograms, and faint cosmic projections. Luminous blue and violet lighting, vibrant J-pop live performance atmosphere, glossy reflections, soft bloom, cinematic depth of field, detailed anime art style. No extra performers, no text.
