Summary:
Luna has had it. She is fed up with Usagi and the other senshi. So she's going to the dark side. Galaxia promises a way to allow Luna's family to become human and Luna takes her offer and goes to work for her. Will Galaxia keep her word or will she throw Luna to the wolves? 

Extra Details:
I would really like this to be funny and light even though Luna is going to the dark side, with a happy ending too. Everyone makes up and Usagi promises to listen to Luna.
