The flashback from the beginning got weird, but once you realize when it all is taking place the story sort of falls into place. Though so much is left open, I don't mind some mystery but it seems more like there were all sorts of relationship issues that got worked out by fighting in the Jinki. Thankfully not much fan service, as I expected with an all female ensemble, but not as many robot fights as would be expected from a robot anime either. If you don't have time to kill it's not worth it, but for something different it was ok and not that great.
