Well, I’m happy about this.
If they hadn’t gotten a second season, I guess that they could have ended rather strongly with the climax of the 12th episode; they could have cut some plot hooks that will only be useful to a second season.
The display of pilots’ faces highlights one serious issue with this series: there aren’t enough strong male characters. There’s one androgynous epicene, and there are lots and lots of pretty girls.
This is a problem with far too many anime shows.
