It is the year 4084. It has been over one thousand years since the Crisis of Systems (Lost Property), which resulted in the destruction of four planetary systems, leaving only a single inhabitable planet, Zion. Mankind is forced to live in space colonies, since that one planet is constantly being invaded by alien life forms that have come to be known as Victim. To stop the aliens and to allow people to land on Zion, mankind has developed the astronomical humanoid weapons, Ingrids, also known as Goddesses. At the G.O.A. (Goddess Operation Academy), young men are trained to pilot the Ingrids. Each of the pilots has a special power called EX; this can consist of a number of skills or abilities, such as the ability to freeze time or to move at extreme speed. The time that a child can control a Goddess is limited and replacements have to be found after a moderate length of time.
