Summary
On January 1, 2000, Earth forces clashed with two different powerful alien forces wanting to take the planet for themselves, the Gishin Empire and Eldar Hordes, in a conflict called the "One Month War". Humanity was able to hold both forces back with a powerful magical source called the Trinity Energy.

Twenty-five years later, both alien factions desire revenge against mankind. However, new hope would come in the form of Satoru Myojin, a Gishin-born man who would see Earth as his home and Toshiya Izuka, a young prodigy who would see the Trinity Energy, the same power that defeated the aliens, unleashed once again, for better and for worse.
