K-ON! episode #1


Yui Hirasawa, a new high school student, wonders if she should join a club or not. Meanwhile, Ritsu Tainaka is trying to revive the school's Light Music Club. Ritsu's childhood friend, Mio Akiyama wonders what club to join. Tsumugi Kotobuki runs into Ritsu while looking for the choir club and Ritsu finds that she must get at least four members to join in order to save the club from being disbanded.


Yui's first day at high school.

Yui is woken up by her sister Ui and believes that she overslept on her first day of high school. She rushes towards the school, but realizes she just got the time wrong after arriving. Sitting in the auditorium with the other first-year students, she is elated by the reality that she's now a high school student.

Yui is clueless about what to do.

During the following weeks, Yui considers joining a school club but doesn't actually commit to one. When she tells her childhood friend and classmate Nodoka about it, she got scolded by her more responsible friend since two weeks had passed without a decision from Yui. Clueless, Yui worries that she won't be able to find something she wants to do.

Mio's, Ritsu's and Yui's first encounter.

At the same time, Ritsu and Mio ask their teacher Sawako Yamanaka about the Light Music Club they are about to re-establish, just to learn that they need at least two more members to save the club from being disbanded. The pair happens to meet Yui for the first time as she enters the teacher's office to pick up some papers. Her clumsiness quickly causes Ritsu and Mio to develop a low opinion of her.

Tsumugi joins the club.

Visiting the music room, Ritsu and Mio wait for a third member to join. After some time, just when Mio is about to give up, Tsumugi shows up searching for the chorus club. Ritsu, excited about a possible member, tries to drag Tsumugi into their club, just to be stopped by Mio. Telling Ritsu off, Mio prepares to leave, but Ritsu reminds her about the promise they made to form a band together after seeing a live concert. Her flashback turns out to be false however, since they made their promise in front of a TV and Mio was never actually very committed to the idea in the first place. Surprisingly, Tsumugi starts laughing, saying that Ritsu and Mio are interesting people and that she'd like to be in a club with them.

Mio, Ritsu and Tsumugi discussing methods to get more members.

All the three now need is a fourth member and they come up with several methods to gather new members, like a recruitment poster. Yui sees the poster and mistakenly assumes that light music equates to easy music like playing castanets. That in mind, she joins the club. It's only after Yui applies that Nodoka explains her mistake to her.

Mio, Ritsu and Mugi trying to convince Yui to stay.

On her way to the clubroom for the first time, Yui gets very nervous since she has no experience with playing an instrument and decides to officially leave the club right away. However, seeing the other member's relief over her saving the club's existence complicates things for her and end in her tearing up over wanting to leave. Ritsu, Mio and Tsumugi feel bad about their selfish methods and apologize to Yui by playing "Tsubasa wo Kudasai" for her. Overwhelmed by the performance, Yui joins the club for real.

The club playing for Yui.

In the last scene, Yui talks with Nodoka about joining, leading the latter to be very worried about the club's future.
