It's the first day on the job for Ai Tanabe as she's introduced to her eccentric co-workers in the Debris Section of space station ISPV-7.

Hachimaki's dream of getting his own spaceship is revealed. Tanabe continues her zero-G training with Hachimaki. Tanabe and Hachimaki are sent on a debris retrieval mission to recover a derelict satellite. However, the satellite's orbit sends it on a collision course with Cheng-Shin's orbital shuttle.

Insurance salespeople swarm the ISPV 7 space station while members of the Debris Section write their annual wills. During a routine debris collection, Yuri, Tanabe, and Hachimaki recover a space coffin containing a famous astronaut. However, an ideological conflict erupts over the fate of the coffin and the body contained in it.

The spoiled son of INTO chairman, Colin Clifford visits the ISPV 7 space station, and goes on a debris hauling mission with the Debris Section. Among the debris retrieved is Colin's camera carelessly left attached to a derelict satellite.

Fee, Hachimaki and Tanabe decide to go to the Moon for their holiday. But on the Lunar Ferry, a pickpocket steals Tanabe's wallet while Hachimaki makes his debut as an actor.

On Hachimaki and Tanabe's visit to the Moon, they meet Tanabe's neighbours... a group of wannabe ninjas who perform ninja techniques through the Moon's lower gravity.

While recovering from an injury, Hachimaki must stay on the Moon to recover. He then meets a girl who is a Lunarian, a person born on the Moon. Hachimaki also meets Harry Roland, a veteran astronaut who is in an adjacent hospital bed.

Tanabe suspects that Fee is having an affair with the division manager Technora Corp, Dolph Azalia. However, Fee is not, and actually is being promoted to assistant chief of Control Section. Meanwhile, the rest of the Debris Section take this opportunity to go on a very difficult debris mission on their own.

Hachimaki's extra-vehicular activity instructor, Gigalt visits the Debris Section as part of a safety inspection. However, on a debris hauling run supervised by Gigalt, the crew of the Toy Box encounter illegal debris dumping activities.

Tanabe is preoccupied with her discovery of Gigalt's illness. Yuri's involvement in a famous high-altitude shuttle accident is revealed. On a routine debris retrieval mission, Yuri finds the only keepsake of his deceased wife.

An engineer from an impoverished country, El Tanika, comes to the ISPV 7 space station to have his new spacesuit tested. No one will have anything to do with his unusual suit because of the lowly status of his home country unil the Debris Section volunteers to help him with the testing.

Fee's quest for a smoke leads her to become entangled in a terrorist plot to stop human development in space by initiating the Kessler Syndrome, destroying the Toy Box in the process of saving the ISPV 7 space station from destruction.
