Interesting.

So, I had a need to look up the human name of the King of Diamonds in Kamen Rider Blade. I don't think his name is ever given on screen (if it is, I've missed it), so I checked my sources. Wikipedia gives it as 金居,　which matches the credits. The one book I have gives it as 金井. Both give the reading "Kanai" which is interesting, because I always spelled it as Kanei.

(I so need to downgrade OS X. The latest upgrade screwed up a number of things, including Japanese text input!)
