Yui Hirasawa has no clue which club to join, but she’s determined to do something this year. As luck would have it, she discovers a flyer for the Light Music Club and decides this is the club for her. But there's one problem: She first must learn guitar!
It's the final year of high school for Yui, Ritsu, Mio, and Mugi, the founding members of the Light Music Club. Together with junior member Azusa, they spend their days in the music room enjoying tea, sweets, and practicing music. Amidst band practice, preparations for the new student orientation performance, and scouting for new members, they still have time for "After School Tea Time." It's a delightfully fun time in K-On!
