they are still alive

A group of anime characters, including a blue-haired figure, a blonde character hanging upside down, and a pink-haired character, are shown in a repeating sequence of a dance or performance in a classroom setting, with the background color shifting between blue, red, green, and pink. The characters move in a synchronized, rhythmic fashion, with the blue-haired character in the center raising their arms and the others positioned around them, while the background color changes in time with the movement.
