I've totally been done in by this girl. After catching up with Ana Ana Shoukai, I love her to pieces. I was also taken by her appearance in one of the SKE concerts I watched lately. She has a good stage presence.
Her live solo was.. hmmmm. I won't say it's great, but it was indeed good. She bombed a few notes, but also had some pretty impressive ones in there, too. Overall I think she has a genuinely nice singing voice. She just needs more training to find her tone.
