Prequel to Swinging Girls

I wonder if any of you have seen the Swing Girls series... If you have, you should know what I mean. Ahahaha~ I'll still introduce all the characters, but they won't be exactly like the originals, since this is a prequel set three years earlier, so some of their traits will have changed. Uh... I put together a character guide, hehe~ It's posted in the first chapter.
