I believe Reni-Chan if the focus of panel 28 (straight bangs) and she grabs Momoka's face. She is interpreting "A Friend" as literally collecting a friend for the hunt.
The first frame of #31 is why I love Kojo Tetsuya.
Kanako is doing the manual labor. Shiorin is as close as possible to the food. Aarin is cheering them on. Momoka is watching the audience. Reni is... err... something-or-other
In a one-frame establishing shot, he gives us the story so far. lol
I think the ones picked on the most is Team Eldest (Reni, Kanako, and Momoka). All in different ways with different reactions. But Momoka is so adorable. Especially when she's acting like an adorable bunny X3
