NieA_7 - Season 1 Episode 7 Mothership, Go-Con & Cloudy Skies Bath
Overview: Chiaki asks Mayuko to go to a Go-Con with her. A Go-Con is a blind date with several guys and several girls in hopes that some of them can pair off. Chiaki reluctantly agrees. Meanwhile, NieA is building a new UFO on the roof when she picks up a signal through her radio. This had happened once before but now is much stronger and appears to be coming from the mother ship. After worrying about what to wear and her hair that need cutting, Mayuko calls Chiaki and tells her that she can't go to the Go-Con after all.
