In the year 179 of the "New Western Calendar", the One Year War breaks out between the Earth Federation and the Principality of Zeon, but is halted when an object crashes to Earth, landing on South Atalia Island. An investigative team from the "Extra-Over Technological Investigative Institute" discovers the object is an alien battleship with highly advanced technology. Despite the warnings of "Dr. Bian Zoldark", the Federation hides the evidence of intelligent, extraterrestrial life, and uses the time to increase their military power. Bian founds the "Divine Crusaders" to utilize the "Extra-Over Technology" found on the ship to devise weapons capable of protecting the Earth from alien forces, should the planet become embroiled in a conflict.
