character: koharu_(blue_archive), A medium shot from a front-facing angle featuring Koharu from Blue Archive dressed as an idol, standing centrally in a celebratory pose. Koharu has long pink hair tied in twintails, pink eyes, and distinctive black feathered wings protruding from her head. She wears a sparkling, ornate idol costume consisting of a decorated top and a wide, stiff skirt that spreads out horizontally in a perfect, flat circle without any waves or ripples. She is holding a glittering microphone in her right hand, gesturing toward the viewer with a bright, beaming smile and a slight blush on her cheeks. The background is a brightly lit concert stage with shimmering spotlights and a blurred cheering crowd in the distance. The visual style is a high-quality anime illustration with a vibrant, saturated color palette, featuring lens flares, floating glitter particles, and a joyful, energetic atmosphere.
