Synopsis

*Based on the new Gunparade Orchestra game for the PS2, a long-awaited continuation for Takidou Gensou Gun Parade March. Both, the anime and the game are simultaneously developed.*

The story of the Gunparade series takes place in an alternate reality. By the end of World War II, in 1945, an alien race called the Genjyu suddenly descended upon the war-torn Earth to take it over. Suddenly, the world has a much bigger thing to worry about than simple matters over pride and land. These aliens are out to wipe out the human race!
United for the first time in human history against an unprecedented threat mankind have fought the Genjyu for over half a century, only to see their world slowly swallowed by the devastating foe invading the planet. Jumping forward to present day (sometime in the year 1999) in the Japanese region of Kyushu we discover the humans are fighting back with newly devised weapons known as Humanoid Walking Tanks (HWT), and the hideous power which is the PBE bomb against the Genjyu \"Brains\" leading the assaults on the few safe havens that remain.

Ishida Sara graduated the staff training school Tositake in Tokyo and is assigned as the troop flight leader of the 4th division of the 108th guard army in Aomori. The troop is lacking any experience though, as nobody has ever encounter the aliens in a real fight. Above all there's somebody amongst the troop who doesn't welcome her. Just in this hard times the Genjyu appear oncemore and the 4th division gets the order to make a sortie and fight them...
