I liked this episode, was interesting to see YuiAzu duo. Azusa sure has strong grip on her, I mean she had mangaed to bring Yui's gades from deap down to light. She easily could have some of the best results in class there.
By the way what was wrong with Yui when they started to preform? Did she get nervouse or what?
Looks like next week it is Sawako, can't wait!
