character: yumemi_riamu. In a medium shot from a slightly low angle, yumemi_riamu is performing at her birthday live concert on a brightly lit stage. She has a radiant, energetic smile and a few droplets of glistening sweat on her forehead and cheeks. She has short pink hair adorned with a sparkling star-shaped hair ornament and a small ahoge. She is wearing a frilly, light-blue idol dress with elaborate lace and ruffles, and a pair of pure white feathered wings are attached to her back. She is posed dynamically, with one hand pointing towards the sky and the other gripping the edge of her skirt. The background is filled with a massive, cheering crowd, their silhouettes visible beneath the stage lights, waving glowing light-blue cyalume glowsticks. The scene is filled with a celebratory atmosphere, featuring bright stage spotlights, floating glitter particles, and a vibrant, high-contrast color palette.
