This episode is one of my favorites in the amount of character interaction. Plus, it's got a proper concert scene! God, I guess wishing for KyoAni to animate an entire concert is probably out of the question. It would be awesome though.
I liked the intro from Ui at the beginning. And the dynamic between the 2 sisters again.
Azusa appears! Manga readers can now rejoice.
Hehe, new class assignments. Now the group is like Lucky Star with the "tsundere" character in a separate class from the "genki girl", the "dojikko" and the "ojou".
I like the moment where Mio teases Ritsu about them being separated and then Ritsu teases back using Mugi.
Poor Mio. At least you now have Nodoka (who apparently got separated from traditional partner, Yui).
The animal cosplay. Sawako, what were you thinking? I'm sure some potential members were scared away.
Maid cosplay. Ritsu's maid cafe came to fruition. Oddly, the only person wearing the costume that fits the type is Mugi.
Mio = kawaii. Sawako = bordering on obsessed.
The Jazz club is seemingly the Light music club's rival.
Mio and her fluffy lyrics.

Covering for Yui - this is why Mio is cool.
Azusa barely moving and then you see her feet = awesome scene.
Next episode: Azusa is Sawako's new target!?
