Field Trip!
The third years go on a school field trip to Kyoto. On the train there, Mio is a little annoyed at Yui's and Ritsu's childish behavior. Mio realizes that she will have to watch over both of them during the trip. After visiting various shrines and attractions, the group returns to the inn where the girls' bad habits continue to annoy Mio. The next day, they have a look around Kyoto, though Mio laments that no one wants to participate in any tourist activities. However, when they get lost on the way back to the train station along with Nodoka's group, Mio gives in to the jokey nature of the others and loosens up for the rest of the trip.

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!
