Space has been cluttered by debris orbiting the earth and moon. With space travel now part of every day life, space debris has become a major concern. In order to clean up space the crew of the DS-12 "Toy Box" has been assembled with a bare bones budget. Hachirota, who is assigned to Toy Box, dreams of one day purchasing his own spacecraft. The only problem is with his dead end job his dream is fading further and further away from him. For now he will just have to focus on the present and that involves training the new and eager rookie Ai Tanabe.
