I always like working on Plot and Setting before characters, so I'm glad we're on the same page on that :P So many people rush right into characters, and by the time set-up is done, they've had to revise or redo it many times. :P

I think Youkai would be messengers of the gods, and there have been a history of them helping humans. However, I think is should have been a while since there was a confirmed case of a Youkai helping a human, so it's rather unexpected. I think it'd be fun having the confusion at first, the suspicions, then the hiring of mystics, and maybe even a part where one of the brothers trying to steal my character :P

Your thoughts?
