I said this before, and it's really shallow of me, but Iwata reminds me of some local girls I don't really get a long with, so that causes a negative bias
But yeah, it's obvious Iwata has all sorts of talents and appeal. She pwned during that kanji writing shukan episode. I think she has a strong personality and I think she'll grow within AKB48 at rapid pace. it should be interesting to see what she can achieve.
