By 2075, venturing to and from Earth, the moon, and space stations has become commonplace for humanity. Nonetheless, technological advancements have brought about a pressing concern: space debris.

The Technora corporation's Debris Collecting Division spearheads the mission to mitigate this issue, featuring their skilled Extravehicular Activity (EVA) technician, Hachirota "Hachimaki" Hoshino, and the latest addition to their team, Ai Tanabe.
