Good Time Girl

A red-haired anime girl in a maroon and white outfit performs a choreographed dance routine, making hand gestures and posing against a swirling red and green background, then transitions to a close-up of her smiling, followed by a dark-haired girl in a similar outfit dancing against a blue grid background with silhouettes, then a blue-haired girl making a heart shape with her hands, all set to music with a consistent visual style.
