The show takes place in Ogikubo, which is the name of the specially designated area in space in the Milky Way where Earthlings and aliens can live together. Luluco is a female middle school student who lives with her father, and no matter where she is, Luluco is a common, "super normal" girl. As she is living her normal life, one day the mysterious transfer student ΑΩ Nova abruptly appears before her. That meeting will change Luluco's fate.

Living an abnormal existence in Ogikubo, an intergalactic melting pot of humans and aliens as well as the only Space Immigration Zone on Earth, Luluco is a bubbly middle school girl who just wants to be normal. One morning, however, her father, who works at the Space Patrol, eats a volatile sleep capsule by mistake and is frozen solid! To make matters worse, Luluco accidentally breaks him, so she hurries off to his office for help. There, the chief of the Space Patrol, Over Justice, hires Luluco as a space temp worker for undercover investigations, so that the institution may crack down on crime within her school. Made to don the Space Patrol suit and sent on her way to mete out justice, Luluco attempts to maintain the image of a normal girl who does not stand out in any way. But she soon discovers that with the automatic systems and inherently zealous judiciousness of the Space Patrol suit, continuing to be normal will be more difficult than she thought.

In the year 2199, Earth is a mere shell of its former glory after a vicious bombardment by the Gamilas Empire. The inhabitants have been forced underground to escape the irradiated surface, but the deadly radiation inches closer and closer to the retreating population. With only one year before complete and utter extermination, time is fast running out and hope is in short supply. So far, any attempt to escape or retaliate has been instantly annihilated by the alien empire—until an emergency transmission from the planet Iscandar in a neighboring galaxy offers a glimmer of hope to save the doomed planet. Covertly, Earth's Self Defense Force constructs a faster than light engine for a journey to Iscandar. Armed with new weapons and a determined crew of fearless navy men, the World War II era battleship Yamato is reborn as Space Battleship Yamato. She and her crew set out on a perilous journey across the stars to save their home and the entire human race.

In the year 2199, the Gamilon race declares war on humans, intent on taking Earth for themselves. The fighters on Earth do everything in their might to keep the planet stable, but alien technology proves to be far too advanced, and the resulting destruction renders the surface of planet Earth completely uninhabitable. The underground shelters are also becoming weak, and if nothing changes, humans will become extinct in less than a year. But just when all seems lost, Queen Starsha from the planet Iscandar offers a helping hand. The key to victory lies in the Cosmo-Cleaner D, which can eliminate the radiation that Earth is suffering from. However, the only way to get a hold of this life-saving device is if someone from Earth goes to Iscandar―148,000 light years away―to retrieve it. The problem is, they have less than a year before time runs out. The fate of the entire human race lies in the hands of the crew of a salvaged WWII craft, the Space Battleship Yamato.

A year has passed since the Star Force returned to save the Earth but another danger now approaches from deep space. A gigantic White Comet hurtles toward our galaxy, obliterating everything in its path. But it is no ordinary comet—it is the deadly Comet Empire, conqueror of worlds... and Earth is the next target! Against orders, the Star Force blasts off to investigate, but even if they can get past the flagship Andromeda, they don't yet know the true nature of their new enemy!
