I like the demon/some other mythical creature hybrid plotline, so if you are still up for roleplaying, I would like to do that one with you if you don't mind. I am Ryuu007 and I just signed up not too long ago and am waiting to get approved though. My character is basically human/nine-tailed kitsune hybrid onmyoji turned to vampire lord/kitsune by his late sworn brother who was actually the Sixth Progenitor after Vlad the First. So he accidentally stumbles upon your character and records her on tape and threatens to sell it to the media unless your character cooperates with him and becomes his personal secretary. In exchange he will not only not divulge her secret but he will also help her deal with being a hybrid being better.
As to what the other half is, I would like it to be giant slime-girl, if its all the same to you. If this interests you, we can talk it out further.
