Two anime characters with glowing eyes face each other, one with blue eyes and white hair, the other with red eyes and black hair. The scene shifts to a glowing blue moon, then to a girl in a red blazer standing on a checkered floor, followed by a view from below of someone standing on a platform above water. The girl reappears in front of the moon, then is shown smiling in a field of flowers.
