This series of ~5 mins long shorts that came with the bluray mainly attempts to put an epilogue to the main storyline. It adds some crucial extra info on some characters, but by and large the point of this was some extra fanservice (not that kind mind you) showcasing cute moments. The first and last episodes are more serious toned and an episode in between can be considered vital (watch to find out why). It sheds some light on what our girls our doing after the events of S3. The series has little animation (not that it needed to) but manages to tell whatever it wastrying to tell. Must watch for fans of the original series.
