Three anime girls in sailor uniforms are depicted. The girl on the left has long pink hair and is smiling widely, holding up her arm as if taking a selfie. A girl with short purple hair is in the foreground, looking forward with a slight smile. Another girl with blonde hair is in the background, looking to the right with an open mouth. A small green rabbit-like creature and a yellow mechanical device are also visible.
