You think they gonna change her name?
That shyt is too hard for most Americans to say.
How though? After you've heard it once, it's not difficult to pronounce. It's the same with Asuka where if you only ever saw it written, you would assume it's 'ah-soo-ka', etc. The only people mispronouncing it are people who never heard the name spoken aloud.
I doubt they'll change it anyway. I think they'll want to use her to draw in Japan, and her name is a lot more well known there than Kairi and Kana/Asuka were
