Re: Akatsuki ranks
Well if the rings work that way, I can think of it to be something like this...
Leader - Blue-Hair/Orochimaru
Kakuzu - Hidan
Those are the only pairings what would be odd. Though if Orochimaru was with Hidan or Kakuzu, it may make some sense if they had to move them around, and got unbalanced after that.
