01. Ishiguro Atsuki - When I first saw her, I knew she was going to be popular because she looks like your typical idol, and she looks like Myao.
Plus she's my favorite Kenkyuusei. :3 She's a really great performer, too.
02. Fujimoto Sara - A lot of people don't seem to like her and she's probably one of the least popular AKB members, but damnit, I like her anyway. Plus I feel so bad for her because she joined the Kenkyuusei a while back, got cut, and now with the upcoming 10th gen, I'm really worried that she's going to get cut again. D:
03. Takamatsu Eri - No particular reason. I just think she's funny and cute.
This is completely biased, too, by the way. These three girls are my top 3 Kenkyuusei.
I haven't seen how she is doing recently, but I'm willing to bet she's improved.
I haven't seen her in the older stages, but she's quite confident on stage and has a lot of energy. Probably one of the better performers out of the Kenkyuusei. =)
