character: mizumiya_su_\(1st_costume\). In a medium shot from a slightly low angle, mizumiya_su_\(1st_costume\) is captured mid-dance on a vibrant concert stage. She is a cute girl with long, light blue hair styled into braided twin-tails with bright pink streaks, her sparkling blue eyes full of energy as she wears a joyful, beaming expression. She is dressed in her 1st costume, consisting of a white hooded jacket worn open over a blue shirt and long sleeves, with delicate water droplet accessories on her person that catch the light. She is posed dynamically, one arm raised and her hands gesturing rhythmically to the music. The background features the dark silhouettes of a cheering audience, contrasted by dazzling, sparkling stage lights and beams of colorful light cutting through the atmosphere. The visual style is a high-quality anime illustration with a bright, cheerful color palette and a shimmering, energetic idol performance mood.
