Miki misunderstood Producer in episode 6 so through episodes 6-10 she had been working hard mainly to get Ritsuko's approval and "be added to Ryuugu Komachi". In episode 11, they announce that RK and the remaining 9 idols will be appearing in live TV thanks to their win at the Idol Olympics whatever and so all the girls start practicing for their appearance. At the end of the episode, after showing how hard the idols worked to "get it right", Miki goes running to Ritsuko and asks her what she thinks of her performance; Ritsuko praises her and Miki, happy due to Ritsuko's praise, asks her if she isn't going to be added to RK, Ritsuko doesn't understand what Miki is talking about and Miki slowly becomes disappointed, realizing that Producer "lied" to her. Right before the credits, Producer and the girls are worried that Miki hasn't arrived to the practice and Producer recieves a message from Miki titled "Really?"; Producer opens the message and it only reads "...liar (><)"
Ah, a misunderstanding. The driving force behind several a plot point. =P I see.
How many episodes was the series greenlit for again? I forgot. Since this is very close to the ending/halfway point for an anime series right now.
Ufufu... maybe a certain extra someone will have their hair cut by this point.
