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.

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.

Edel's past finally catches up to her when an old flame comes to the ISPV 7 space station. Meanwhile, Hachimaki struggles with his date with Tanabe.

Claire has been demoted from working in Control Section to replacing Hachimaki in Debris Section. Hachimaki and Hakim encounter unexpected difficulties completing a 10-day group endurance test, the second round of testing for those wishing to join the Von Braun.

With Tanabe fully recovered, she and Hachimaki visit the ISPV 7 Space Station.
