It began in 1945, at the end of the Pacific War. Alien invaders filled the earth's Skies, and mankind was forced to confront an unprecedented threat. For the first time in human history, people of all cultures came together under one banner.

This war has now been raging for over fifty years. Countless lives have been lost, and the Japanese military is now forced to rely on young people such as Atsushi Hayami and his high school class, also known as Unit 5121. This new generation fearlessly struggles on with the aid of the HWT humanoid combat machines and the devastating PBE bomb.

The story focuses and revolves around the 108th Guard Squad, stationed in Aomori. A poorly equipped unit with very little military standing, it is often viewed as a 'reject camp' for pilots not making the grade for the elite units based in Hokkaido. The apparent helpless nature of this force is hardly a deterrent for the encroaching enemy armies, ever closing in on both the 108th and the rest of the empire. The young pilots of the 108th, who had dreamed on returning home, are plunged forcefully and unwillingly into a war.
