Welcome to the Light Music Club!

When Yui Hirasawa enters high school, she wants to join a club but can't decide which one is right for her. Fortunately, the Light Music Club is desperate to find another member or else they'll be disbanded! With the enticement of delicious snacks and assurances that no musical experience is necessary, Yui joins up, becoming the guitarist in this all-girl high school rock band. Together with Mio Akiyama on bass, Tsumugi Kotobuki on keyboard, and Ritsu Tainaka on drums, they're going to rock the school and someday make it to the Budokan! Now, if only they can just put down the snacks long enough to practice...
