character: nakasu_kasumi, character: hoshino_(swimsuit)_(blue_archive), Vibrant anime illustration of nakasu_kasumi cosplaying as hoshino in a blue_archive swimsuit, captured in a medium shot at poolside. Nakasu_kasumi, with short brown bob-cut hair featuring an asymmetrical bow, red eyes, mischievous smile, and pink halo floating above, strikes a playful pose with hands on hips, wearing a white frilled bikini swimsuit under an open blue jacket with sunglasses perched on her head. Her right hand holds a large pink inflatable floatie armband casually. She leans forward slightly, legs together, exuding summer energy. Sparkling turquoise pool water with gentle ripples in the background, lounge chairs and umbrellas dotting the sunny deck under a clear blue sky. Bright, saturated color palette with glossy highlights on skin and fabric, bokeh depth of field, joyful and vibrant summer atmosphere, great quality rendering with intricate details on textures and water reflections.
