Just watched it again and there's still so much space for everyone else to grow and develop. The scenes showcasing Yui and Ui's relationship was definitely a step in the right direction and was a joy to watch. I guess all those scenes with Sawa-chan is still excusable because it's not like she's on screen all the time. I still find it sad and wasteful that we still don't get to focus as much on everyone else sans Mio. I mean, like I said, one girl does not a band make.
Still, while it seems Yui and the new girl will become the spotlight for the next coming episodes, that still leaves out poor Ritsu and Mugi.
