The Solnoid race is long dead, annihilated along with their enemies in the final battle at Sigma Narse. But their descendants survive on Earth, and have now inherited the sad destiny predicted so many years before. The year is 2085. The third world war between East and West has reduced the cities of Earth to mountains of rubble. The mechanical killing machines created by both sides now ruthlessly hunt down the remnants of humanity. Old hatreds between human factions prevent an effective resistance, and the only hope for survival rests in a desperate plan: evacuate the survivors to Mars Base. There they can rebuild and plan the liberation of the home world. Among them, one young woman carries the guilt of her father`s hand in the destruction of civilization. Unknown to her, she also carries the key to a possible salvation. As destiny draws new friends and allies to her, a new Gall Force is born to rise up against the coming destruction...

The very first original animated video produced by Tezuka Productions about an agent who was sent riding on Halley's comet to the Earth. He was actually, though, given the order to destroy the Earth. Captivated by planet's beauty, however, he is no longer able to destroy the planet. Seventy-six years later, another agent from Halley's comet is sent to the earth to liquidate this traitor, who is now disguised as a girl named Lamina in Vietnam. Tezuka Osamu oversaw only the original story.

In 1999, a special mystery/paranormal investigative unit consisting of five youths is formed. The series uses a mix of real tokusatsu footage (vehicle scenes) and animation (character drama).

The OVA will be pre-sold during the Comiket 87 starting on December 28, 2014, regular retail distribution of the limited edition package will start on January 30, 2015.
