You'll need to play FFX twice or so to really appreciate him, and unfortunately, there isn't much of an incentive to do so, unless you wanted to hear the Al Bhed translated THAT badly.
Huh? He translates Al Bhed?
No. I was referring to the "compile Al Bhed" primers function that can be found in certain places in Spira. Translation books can jump save files, and is independent of any Kimahri awesomeness.
