Toy Box (DS-12) is the main spaceship of Planetes (Anime). It is a debris ship of the Space Debris Section, a unit of Technora Corporation. The Debris Section's purpose is to prevent the damage or destruction of satellites, space stations and spacecraft from collision with debris in Earth's and the Moon's orbits. They use a number of methods to dispose of the debris (mainly by burning it via atmospheric reentry or through salvage), accomplished through the use of EVA suits.
