hmmm any idea who is the other akatsuki guy who have not yet reveal himself??
Asmodean's killer... j/k
There seems to be no hints, at all, on that member's identity, besides the possibility of being a woman. Given the lack of hints, it is quite complicated for anyone to try to think of any possible ideas on the identity of that member.
What you are asking here, my friend, is for people to give you random ideas, without any base. That will not help you at all. Not only that, but taking into consideration what I said in the previous paragraph, the fact that you asked for something that the readers cannot know (at least, for now) may get you flamed.
So, what's the lesson? Do not ask for things that the readers do not, and cannot know, due to lack of information.
Well, and when it's something we can't really speculate about, either. Not much to go on.
