It is the day of the graduation ceremony for the seniors of Sakuragaoka High School.
Azusa's seniors have asked her to come to the music room. When she gets there, it's just another day at the Light Music Club with Yui and Ritsu playing with the popping sound of their diploma tubes. The girls are having one last tea part in the music room. While chatting, they reflect on their last three years in the school and in the club. Starting from how Ritsu rebuilt the club, to Yui legitimizing the club as its 4th member, to Azusa joining the club. They talk about their reasons for joining the club, and about their impressions of one another. Azusa can ramble on for ages, nit picking every little thing she doesn't like about Yui - not knowing how to maintain her guitar, being unable to read sheet music, all of the constant hugging, the nickname 'Azu-nyan'. But at the end of it all, Azusa loved being in the band, and she loved how cheerful Yui always was.
Sobbing and shaking, she has one last request - that her seniors not graduate. Yui gives Azusa a big hug, wipes away her tears, then tells her why they asked her to come up to the club room. The four girls had prepared one last song. Even with Ritsu's messy tempos, Mio's bass put down a steady groove. And even though none of the four actually played perfectly, Azusa knew that she was drawn to the band by the same warmness and support hey had for one another, just like when she first saw them at the opening concert. After the song, Azusa, as the new club president, vows to make the club even better. With that, Yui, Mio, Ritsu, and Tsumugi say goodbye to the club room.
While flicking through the club's photo album, Jun and Ui give Azusa some exciting news - two more students wish to join the club! At first, Azusa doesn't realize that the 'two students' are actually Jun and Ui. Jun did actually promise she'd join at one point, and with Yui moving out to university, Ui has the time to practice.
The four seniors then walk home together, but it all feels surreal. But one thing they know for sure is that they're going to university, and it's going to be a lot of fun.
