The Sakuragoaka Girls Academy curriculum traditionally focuses on the three "R"s of reading, writing and arithmetic, but Ritsu Tainaka wants to add two more "R"s: Rock and Roll! To do that, however, Ritsu has to save the Light Music Club from being shut down due to little problems like not having any other members or a faculty advisor. After strong-arming her best friend Mio into joining and convincing Tsumugi Kotobuki to make it a trio, Ritsus would-be rockers are soon only one talented guitarist short of the quartet they need for school approval. What they get, unfortunately, is Yui Hirasawa, whos never held a guitar in her life, but shes determined to learn! Will the school halls come alive with the sound of music? Find out as four outrageous girls band together in K-On!!
