Lol, I was contemplating on Yukki's pose for Type A as well. Maybe she leans on the mirror? Otherwise I don't see any possible explanation, where she doesn't lose her balance soon.
For Annya and Yukki faces: I consider them normal for those two. Yukki often looks kinda clueless and Annya loves to do weird faces. In her case I find her look on Type A much more interesting: She looks so bored/annoyed there.
Did you see that they also keep the popularity of the members in place: The 4 popular ones in front, the other 3 in the back? It never occurred to me before that PASSPO is very strict on that, until someone mentioned it to me.
Hmmm, a steak restaurant...
