Just starting high school, Yui is having trouble fitting in and decides to join the light music club. But she first must buy and learn guitar.

Yui wants a guitar that is too expensive. All the band girls get part-time jobs to save up for the guitar. Yui might actually get it through a twist of fate.

It’s time to take midterm exams, but Yui is too busy practicing guitar that she ends up failing. She must pass the retest or the band must breakup.

Mio is inspired by finding a tape of the previous club's performance, and gets the band together to practice over the summer for an upcoming school festival.

Three days left 'til the music festival, the girls are still not officially recognized as a club. Ritsu blackmails a previous club member to be their advisor.

The band plays the school festival. Mio trips and exposes her underwear to the audience. She ends up getting a fan club, but is scarred by the embarrassment.

The second year of school begins! The Light Music Club tries to gather by any means necessary.

Azusa Nakano joins the Light Music Club but realizes that the laid-back club might not be for her, and Azusa’s membership is at stake.

The girls go on another training camp with their new member. Despite Azusa’s nagging, she’s the one that plays the most.

The annual school festival is getting closer and the Light Music club will be performing again... however, Mio and Ritsu get into an argument.

Yu gets a fever. Will she recover in time for the festival?
