The Galman Empire is destroyed but the planet Galmania is not, by a chance collision of galaxies. The Bolar Federation worlds including Planet Bolar are destroyed. The Yamato, back under the command of Captain Okita, encounters the planet Denguil too late to save its humanoid civilization from being flooded by the water planet Aquarius. The surviving Denguil, a warrior race who believe only the strong should survive, plan to use Aquarius to flood Earth and destroy humanity, in order to create a new home for their race.

Shin Kazama, tricked and forced into flying for the remote country of Aslan, can only escape the hell of war by earning money for shooting down enemy planes or die trying. Through the course of the series, Shin must deal with the consequences of killing and friends dying around him as tries to keep his mind on freeing himself from this nightmare.

When vile aliens known as the Gamilons wreak nuclear havoc on Earth, a group of survivors refit the Japanese battleship Yamato for intergalactic travel and set off on a mission to retrieve a neutralizer that will eradicate the radiation from Earth's atmosphere.
