At twilight during a summer festival, in a traditional riverside town lined with glowing lanterns. A cute girl wearing a pale lavender yukata is depicted from the waist up. The yukata has blue-purple morning glory and small flower patterns, with a large dark purple obi knot on her back. The girl has brown hair styled in a soft updo, adorned with a purple flower ornament and dangling accessories. The camera is at a slightly high angle from behind the girl. She has both arms spread wide, holding a lit handheld sparkler in each hand. She is captured in a moment of spinning happily, her yukata sleeves spreading wide in the wind. She is looking back over her shoulder toward the viewer, cheeks slightly flushed, with her mouth open and eyes narrowed in a bright, joyful smile. Golden fine sparks spread from the sparklers in both hands, warmly illuminating the contours of her face,hair, and yukata. In the background are lanterns reflecting on the river surface, wooden townhouses, stone-paved promenades, railings, a small bridge, and a sky changing from sunset to deep indigo. The girl is the main subject in the foreground, with the background moderately blurred.
