Sayubi and Karin are calm during singing + high notes, Karin, Yuka, and Akari own the photoshoots, and Tomoko is simply awesome XD Akari working the belly button + pants style, it's amazing. I honestly think that if she can heighten her singing level then she has an amazing chance of center position because she captures the "cool, fresh, but mature" look the group is going for. Her dancing's pretty good also from what I've noticed.
