Ritsu Tainaka, called Ricchan by [Tsumugi Kotobuki](https://anilist.co/character/19568/Tsumugi-Kotobuki) and [Yui Hirasawa](https://anilist.co/character/19565/Yui-Hirasawa), is one of the 5 main characters in K-ON!.

She is the self-appointed president of the Light Music Club and the drummer of the band Ho-kago Tea Time. She was the one who rebooted the Light Music Club when it was on the verge of being disbanded, and has become the natural leader of the club since then.

Ritsu plays a yellow Rick Marotta Signature Yamaha Hipgig drum kit with an add-on floor tom (in the opening credits only) combined with a cymbal set from Avedis Zildjian, though is shown playing a white Yamaha Absolute Series drumkit in the anime's closing credits.

Hirasawa Yui, a young, carefree girl entering high school, has her imagination instantly captured when she sees a poster advertising the ‘Light Music Club’. Being the carefree girl that she is, she quickly signs up. However, Yui has a problem, she is unable to play an instrument. 
When Yui goes to the clubroom to explain, she's greeted by the other members: Ritsu, Mio and Tsumugi. Although disheartened at Yui’s lack of musical know-how, they still try to convince her to stay to prevent the club’s disbandment. After playing Yui a short piece which re-ignites her imagination, they succeed in keeping their new member and guitarist. 
Along with the tasks of school and homework, Yui begins to learn the guitar with the help of the other band members, experiencing many mishaps along the way. However, with the school-festival drawing near and Yui getting stuck with her practice, will the Light Music Club be ready in time for their debut?

Born in Hong Kong and studied in Los Angeles.  Works as a voice actor for Red Angel Media (Animax dubs).

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!

With graduation right around the corner, every member of the Light Music Club except for Azusa will be leaving for good. But the girls aren’t going to let something as silly as graduation tear them apart! For their final hurrah, the girls are going on the ultimate vacation tour— all the way to London! Their overseas journey will lead them on a trip of discovery and friendship as they take the stage one last time for their final encore together.

When their high school's pop-music club is about to be disbanded due to lack of interest, four girls step up to fill the membership quota. Unfortunately, lead guitarist Yui Hirasawa has never played an instrument in her life. Ever. And although she likes the idea of being in a band, standing in front of the mirror posing with her guitar is a lot easier than actually playing it. It's gonna be a while before this motley crew is rocking out, but with their spunk and determination cranked to 11, anything is possible!

Ritsu's middle school friend invites the band to perform live on New Year's Eve. The girls get acquainted with other bands, and become a little nervous as the performance approaches. When the time comes, will they be able to rock the house?

A special episode of K-ON!! released in the ninth volume of Blu-ray and DVD. The girls plan a trip abroad and go to the passport office to apply for passports.

Yui, Mio, Ritsu, and Tsumugi embark on their college adventures! It will take some time for the girls to get used to life away from their families and adjust to the pace of college life, but there's one aspect of their new situation that there's no uncertainty about-joining the pop music club! But they aren't the only high school band making their debut on the college scene. Is Afterschool Tea Time ready to perform alongside the hard-rocking rhythms of The Girlz?!

As the only member of the pop music club not to graduate, the responsibility of recruiting new members has fallen to Azusa. Ui and Jun have agreed to help out their friend, but they might be more interested in having actual afterschool teatime than making music. Even when Azusa secures the necessary four members to keep the club alive, the lack of musical experience (and musical instruments) is going to be a challenge! Will the high school pop music club survive to take the stage once more?!
