Shining at first place is the idol group Momoiro Clover Z. There have been news about their "graduating" from Koukaku but it can't be denied that it has been a successful year of them. In this year's January, they made a collaboration with the famous KISS, and since it's the first time of KISS working together with the Japanese, Yume no Ukiyo ni Saitemina has gone viral.
Their (Momokuro) single sales may not as huge as AKB48's, but it's proudly to say that their concert attracts the most fans. "I didn't buy the CD but I still want to watch their concerts". (And there're things about Maku ga Agaru, CM “Hustle" collaborating with Arale-chan, there's no scandal among the girls).

Then we have Shiritsu Ebisu Chuugaku of Hirota Aika, the girl who has a very unique voice that can stir up the atmosphere in the living room.
