Story
Year 2065 AD. After the failure of the first Integrated Earth State to advance into the outer planets, a huge mobile weapons army suddenly appeared in the jet-black space. They challenged the Integrated Earth State and destroyed the SDF (Space Force).

"We have taken control of the Earth. Your future lives are forfeit!"

Calling themselves "Moon Child", they conquered Earth and captured a few remaining SDF soldiers who were sent to a colony under construction. While most soldiers are overtaken by despair, some still do not give up hope... A teenage girl and a genius pilot, Ellinor Waizen...

The special fighter GG Aleste, developed specially for her, was secretly brought into the colony by the development team led by Ellinor's grandfather Seft Waizen. Ellinor now heads into the void where the battle awaits, piloting the GG Aleste to save the Earth.
