How/when you got to know her: It was during the time of A4r, K4, B3, when my favorite was still Maimai but she was on TV so much and so busy working outside of the theater. Many people, myself included, thought she'd graduate at the end of A4. She was hardly performing at the theater at all and when she was, I wouldn't win a ticket. Feeling I should be prepared for her leaving, I decided to pay more attention to all the other girls because I think that having a favorite member to support can make things easier but I didn't want to feel forced to pick a replacement. At that time, Asuka was pretty much unknown outside of the theater. She had just been promoted to Team K a few months earlier, LODs didn't exist and she wasn't on TV at all. And during the team songs, she wasn't exactly prominent either. At first I didn't even notice but watching K shows, I eventually found myself watching only her whenever she was on stage. Despite being in the back or on the sides a lot, she always smiled, always shined - it felt good watching her give her best. Even before Maimai had left, I had found my new favorite and I'm really happy that it happend like that.
My favorite thing(s) about her: She really shines on stage and she looks much better in person than on TV or pictures. Her dancing isn't the best but she has a really nice voice to make up for it and she can also be quite funny if given a chance to talk.
My disliked thing(s) about her: Right now, there aren't any...
A memorable performance: Haru ga kuru made, during AX2008. I wish she could've sung it with Maimai instead of Michiru....
A moment that made me laugh: During an LOD, a fan interrupted her introduction, praising her. She was so confused that she totally forgot what she wanted to say. So cute.
A moment that surprised me: Her birthday show this year. It was so full of emotions and apparently her pictures in Flash caused more trouble than we thought.
A picture that I like: There are quite a few, especially the mid-2008 gachas but I don't have scans of them. The one Barrie posted is also great and of course this one:
Edit:
Like these:
A video that I like: Basically all of them. The first episode of Suiensaa was nice, she was very cute in that.
I'm happy that she's become more popular since then but I also hope she's given more chances to shine in the future. Fanboy talk aside, I think she's got a lot more potential that she simply couldn't show yet.
