A girl with long blue hair stands with her back to the viewer on a glowing hopscotch grid in a starry, nebula-filled sky, hopping from one numbered square to the next in a continuous loop. She moves forward across the grid, stepping on numbers like 1, 2, 3, 6, 7, 10, and 15, with her arms outstretched for balance, before jumping with her arms raised in the final frame.
