The entire show is a shallow teen girl fantasy. The long and short of it is a bunch of teen girls play around in space with ships that people just give to them for no explainable reason with a few shoujo guys. The characters are all bland, there's no character development - a bunch of teen school girls are just automatically great pirates from the start -, there's no plot, there's no danger or excitement, there's nothing. The entire show is as if the author just took a teen girl's daydream "well, when I was 13, I wanted to have a pink pirate ship (yes, a squad of teen schoolgirls have a pink pirate ship) I could play on with my friends" and then made that into an anime.
