No Club Room!
The club room is closed for repairs, leaving the girls nowhere for practice. While trying to find a suitable location for their practicing, the girls try to come up with lyrics for the song Tsumugi wrote. Failing to find anywhere in the school to practice, they rent out a studio, but end up wasting time discussing lyrics and run out of time before they can practice, though the club room reopens the next day. The following night, Ui helps Yui write some lyrics, but ends up catching a cold, leaving Yui, who has always relied on her, to look after her instead. Realizing how important she is to her, Yui writes some lyrics dedicated to Ui, which are approved by the other club members.

K-ON! Season 2
It is the new year, which means that the senior members of the Light Music Club are now third-years, with Azusa Nakano being the only second-year. The seniors soon realize that Azusa will be the only member left once they graduate and decide to recruit new members. Despite trying many methods of attracting underclassmen—handing out fliers, bringing people into the clubroom, and performing at the welcoming ceremony—there are no signs of anyone that plans to join.
While heading to the clubroom, Azusa overhears Yui Hirasawa say that the club is fine with only five people and that they can do many fun things together. Changing her mind, she decides that they do not need to recruit any members for the time being.
K-On!! revolves around the members of the Light Music Club as they experience their daily high school life. From rehearsing for concerts to just messing around, they are ready to make their last year together an exciting one!
