In the distant future, mankind is divided into two factions: Union and Deague. They have waged a war against each other for so long that no one remembers when it first began. The backbone of the Union military is the manned weapons system Strain, while the Deague uses an unmanned version, the Tumoru.
Sara Werec, the daughter of a respectable family, is a 16-yearold girl who attends Grapera Space Armed Soldier Academy located in the Cranial Solar System, where she is training to become a full-fledged Reasoner (a Strain pilot).
Her brother, Ralph Werec, had been sent to the frontline 130 light-years away to accomplish a special mission when she was 11 years old, a distance that requires 400 years of objective time to traverse by even the fastest Union spacecraft. However, in accordance with the theory of relativity, this corresponds to only two subjective years (time as experienced by those within the spacecraft).
The two of them had lost their parents when they were young and the bond between the two is very close. It is Sara’s dearest wish to be reunited with her brother. To do that, she must travel to the battlefield where he is.
One day, Sara’s planet is suddenly assaulted by Deague forces. To her surprise, her brother, Ralph, turns out to be one of the raiders who successfully kidnap a mysterious girl sleeping in a capsule.
In order to find the truth, Sara gets in a Strain and chases after him. However, she is attacked by Ralph, and the Mimic, a copy of the pilot’s brain which is essential to controlling the Strain, is damaged.

1. Planetes
In 2075, space travel is no longer just a dream, but an everyday reality for mankind. Advancements in science and technology have led to the colonization of the moon, the commercialization of outer space, and the formation of large space corporations. Ai Tanabe, an upbeat woman whose interests lie in the cosmos, joins Technora Corporation as a member of their Debris Section, a department dedicated to the removal of dangerous space junk between the orbits of the Earth and Moon.
However, Ai soon discovers how unappreciated her job is. As the laughingstock of Technora, the Debris Section is severely understaffed, poorly funded, and is forced to use a dilapidated spaceship nicknamed the "Toy Box" for debris retrieval. Undeterred, Ai perseveres and gradually becomes acquainted with the strange personalities that make up the Debris Section's staff, such as the bumbling but good-natured chief clerk Philippe Myers; the mysterious and tight-lipped temp worker Edelgard Rivera; and the hotheaded and passionate Hachirota Hoshino, who longs for a spaceship to call his own.
