The grounds of Paradise Elementary School are forever altered as a massive sword crashes down, giving the school the power to fly through the skies. With Earth under attack by extraterrestrial foes, the fate of the entire planet falls to a group of young children who must pilot powerful mecha to stop the invasion and save humanity from destruction. While originally planned as an anime, the idea was instead turned into a promotional video to announce its serialization in Monthly Daiteioh magazine.
