I've been wanting to do a fox spirit x human roleplay. Basically, the fox spirit, one of the strongest of his age, was bound by a human just over 500 years ago. This human was a powerful shaman. At the moment of his death, the human told the fox that he would reincarnate in exactly 500 years, and that the fox would serve him again. So for the past X years (your character's age) the fox has been looking for his master on that promise. However, the master has now reincarnated as female, and she's still completely unaware of the spirit world. 

Doesn't have to be anime style and such of course. It's just that I really like the idea of fox spirits. As in, they have a clear ranking system with the amount of tails they have, they can shape shift into humans, and...well, foxes are beautiful creatures. ^^;;

As for my posting habits, I usually post between 2 and 3 paragraphs, sometimes 1 or 4 if I have a lot of or very little inspiration for a post. And on average I post once or twice a week, since real life is keeping me busy as well these days.
