Positioned in the midst of Akihabara, Kanda and Jinbocho, the traditional Otonokizaka Academy is on the brink of reorganization. Nine girls rise up to this school crisis! In order to save the school, the girls have decided to... become idols!? The girls' challenges start here...
Takami Chika dreams of becoming a schoolgirl idol, just like the famous μ's (Muse)! Like they did, she wants to save her own school from closing by starting her own School Idol Club. But... "It's impossible for small-town kids like us to become idols." "Why isn't anyone interested?" "Perhaps they're holding back because they think it's impossible?" Can Chika make her dreams come true?
As the only member of the pop music club not to graduate, the responsibility of recruiting new members has fallen to Azusa. Ui and Jun have agreed to help out their friend, but they might be more interested in having actual afterschool teatime than making music. Even when Azusa secures the necessary four members to keep the club alive, the lack of musical experience (and musical instruments) is going to be a challenge! Will the high school pop music club survive to take the stage once more?!
It's the first day of high school, and plenty of school clubs are doing their best to recruit new members, but for ditzy Yui, none of them seem to fit the bill. However, when she accidentally signs up to join the light music club, Yui begins a hilarious adventure to become a world class guitarist! There's just one problem: she's never played the guitar before in her life! Joined by bassist Mio, drummer Ritsu and keyboardist Tsumugi, Yui and the gang will juggle their studies with buying instruments, learning how to read music and even performing in the school festival, all in the hopes of someday becoming a successful band!
