Some delayed comments.
The power to magically summon glass to shank people with. Alternately, bartending.
That's nothin', my cat is 15 years old, and she's somehow still kicking.
Also, in regards to Naruto, I'll admit that the Raikage handled Naruto's interference in his travel to the summit site in a much more civil manner than I would have expected. He let him speak, he responded to his plea with silence at best and a reaffirmation that he will kill Sasuke at worst, and even stepped around him as opposed to pushing him aside when he tried to block him. That man has more patience with Naruto than Karui could ever stand to have, and this is the same man who punched a hole in the table when one of the other Kage brought up his brother getting kidnapped by the Akatsuki. Respect.
