I have the US release. Kira and her adorable swimsuit are definitely intact, no change whatsoever. The other things are not in the game- because the other things, as you've pointed out, never existed at all. =/
THESE CHARACTERS... THEY'RE SO IMPROBABLE! Music is kinda meh, but I always wanted to play a fighting game on a swimsuit. I wonder what the game over screen looks like?
