About Fafner: Dead Aggressor: Heaven and Earth
The year is 2148. Two years have passed since the world was defended from the mysterious aliens "Festum“, leaving the world in peace. The youths and inhabitants of Tatsumiya Island have recovered and continue to live their everyday lives in the newfound peace.
Soushi promised Kazuki that he would one day return to Tatsumiya Island but instead he keeps himself hidden. Kazuki still clings to the promise his fallen friend Soushi made to him to return to the island and set things right again. Kazuki's hopes flare when a life form is detected within an unmanned submarine that comes floating into Tatsumiya Bay one night, but the person aboard isn't Soushi; it is a mysterious "boy" named Misao Kurusu who may not be entirely human, and who claims to have been sent by Soushi. With Misao's arrival, hostilities break out anew between the Human Army and the Festum, and the Fafner pilots are thrown into the most desperate battle of their lives.
