クール系アイドル

A young woman in an anime style, standing confidently on a stage. She has long, sleek silver hair styled in a low side-ponytail, and piercing, cool blue eyes. Her gaze is sharp and focused, conveying a cool, confident aura. She wears a stylish, modern idol outfit: a sleek, dark blue and white jacket with a short, pleated skirt. The jacket has metallic accents and a high collar, and she wears matching arm-length gloves. The stage around her is filled with a cool, blue-toned light, with spotlights highlighting her figure. Her expression is calm and composed, with a slight, confident smile. She holds a microphone in one hand, while the other rests gracefully at her side. Her posture is poised and elegant, embodying the essence of a cool, composed idol. The atmosphere is vibrant and electric, with the glow of concert lights creating a dynamic and immersive scene, all rendered with sharp, detailed linework and vibrant anime-style coloring.
