This is a misty thread.

I mean... the pack I have came with a Gardevior folder... but I find any hentai involving pokemon to be ew, and this is a Misty thread anyway.

Good, then you're not a furry.

Oh, really? I've never really partook in anything Pokemon except for the first three games when I was around 10 years old. lol 香澄 is what I would assume her name would be, going by IME. http://jisho.org/kanji/details/%E9%A6%99%E6%BE%84
I could be wrong on that, though, but that's the most common "Kasumi" according to the IME program.

There's also 加寿美　鹿住　香純　佳澄　I don't know if any of these are actually names, though. Lol

Kasumi is in katakana in the series. All Pokemon related characters use kana for their names. カスミ can turn into a lot of combinations according to IME, as you posted. I don't read too much into kanji that are only really used for names (why focus on those before you get the useful ones out of the way?)

So I wouldn't know what kanji would actually form her name.

Edit - But カスミ translates into "mist" without any kanji if I roll Rikaichan over it.

 Spoiler

So I would guess it's 翳 or 霞. Both mean mist/haze, so it works out fine.
