By 2075, traveling through space has become an ordinary part of daily life rather than a distant fantasy. Scientific and technological progress has enabled lunar colonization, the commercialization of outer space, and the rise of massive space corporations.

Ai quickly realizes how little respect her role commands. The Debris Section is the butt of jokes at Technora: chronically understaffed, barely funded, and forced to operate a worn-out spaceship nicknamed the "Toy Box" for its debris retrieval missions. Unfazed, Ai presses on and grows familiar with the quirky crew members, including the clumsy yet kind-hearted chief clerk Philippe Myers; the mysterious, tight-lipped temporary worker Edelgard Rivera; and the hot-tempered, passionate Hachirouta Hoshino, who dreams of owning his own spaceship.
