History
Under the command of Ken Sanada dedicated to foiling the Rara Army's plans for world domination. The EDF employs many soldiers, but relies solely upon the three Core Robots in battle.
Combat between the two armies is quite different from normal warfare; Rara informs the public where and when an attack will take place, and the combat zone is evacuated. At any time, either side can submit a "callsign," indicating their surrender. Because of these measures, there have been no casualties in the war.
