haha!
Okay, let me see if I can explain this the best way ever...
Essentially the idea is to make your own characters, these can be based off the original Sailor Scouts or new characters (for example, you can play a version of Mars/Rei). The idea is to play darker versions of the scouts with a Cthulhoid dark twist to it.
Ideas might include something like Sailor Carcosa, Sailor Yuggoth, Sailor Kadath or so on and so forth. Think dark and twisted if you don't know much about the Cthulhu Mythos. The game would use the Sailor Moon RPG system from Guardians of Order (I've had this book for years and damn it I'm going to use it to run or play in a game of this!!)
Right now I am just seeing if there is interest in it. If not in that, then in a normal Sailor Moon game. Just let me know where the interest lies.
