[Introduction to K-On!]
Detailed video inside. In spring, when the new students are deciding on their club activities, Tainaka Ritsu drags her childhood friend Akiyama Mio to join the "Light Music Club". They then find out that if they can't gather four members, the club will be dissolved. After the addition of rich-girl guitarist Kotobuki Tsumugi, they are still one person short. At this moment, a girl who mistook the club name, the protagonist of this series, Houjou Yui, joins the club. She is a newcomer who can't even read sheet music and has poor academic performance. And yet, these four girls embark on a musical journey that resonates with the sounds of youth.
