Tormented by a space flight accident that took the life of his beloved wife, Yuri is, six years later, a member of a debris cleanup crew aboard a ship named the Toy Box, tasked with clearing space junk from orbital paths. The crew includes Hachimaki, a skilled debris specialist with a sailor's connection to the orbital ocean; Fee, a chain-smoking tomboy beauty with a rough demeanor; and Pops, a veteran orbital mechanic whose fatherly presence helps ease the job's stress.
