One day, out of the blue, the five worlds were linked together. Our blue world, Earth. The black world, ruled by night and magic, Darknes Embrace. The red world, protected by prayer and by the gods: Tera Rubily Aurora. The white world, managed by science and computers: System White Egma. The green world, governed by weapons and armies: Glynnesert. Meanwhile, in each of the worlds, there was an emergence of girls possessing special "Exceed" abilities. The girls would come to be known as the Progress. There, the girls would meet. The world is on the verge of doom. Only the Progress can save it.
