Awesome pic, but since the second fanbook said his name was "A" should the tag be changed from "Raikage" to "A_(Naruto)"? We did the same thing with the Mizukage (although with her we had at least seen another Mizukage besides her).
That's what the Ei tag is for. エー = Ei = A. I wasn't sure how to handle it at first, whether "Ei" or the literal "A" was what Kishimoto was going for, but decided to play it safe. Until something comes out that says, "spell it this way," that's the best route, IMO.
Anyway, I wish there was good, original Killer Bee or Danzou art out there that I could post, too, but that isn't the case.
