Sakuma Yukari decided to start a band on her own after seeing a certain band during the Sakura High School festival, then with her best friend Shimizu Kaede, they want to join the Light Music Club only to discover that in their school there isn't a club like that. With help from Sawabe Maho, they discover there is a Light Music Appreciation Society with only one member, Satou Riko.

When their high school’s pop-music club is about to be disbanded due to lack of interest, four girls step up to fill the membership quota. Unfortunately, lead guitarist Yui Hirasawa has never played an instrument in her life. Ever. And although she likes the idea of being in a band, standing in front of the mirror posing with her guitar is a lot easier than actually playing it. It’s gonna be a while before this motley crew is rocking out, but with their spunk and determination cranked to 11, anything is possible!
