Season 1 of YuruYuri: Happy Go Lily premiered on July 5, 2011.

After a year in grade school without her childhood friends, first year student Akari Akaza is finally reunited with second years Yui Funami and Kyouko Toshinou at their all-girls' middle school. During the duo's first year, Yui and Kyouko formed the "Amusement Club" which occupies the now nonexistent Tea Club's room. Shortly after Akari joins, one of her fellow classmates, Chinatsu Yoshikawa, pays the trio a visit under the impression that they are the Tea Club; it is only once the three girls explain that the Tea Club has been disbanded that they can convince Chinatsu to join the Amusement Club—a group with no purpose other than to provide entertainment for its members.

This is an eccentric comedy about a group of girls who spend their spare time drinking tea and fawning over each other, all while completely failing to even notice the supposed main character Akari amongst them.

Season 2 of YuruYuri: Happy Go Lily premiered on July 2, 2012.

The girls of the Amusement Club return in Yuru Yuri♪♪, finding new ways to make passing time even more enjoyable. Their members consist of the always energetic Kyouko Toshinou; calm and sensible Yui Funami; polite but often overlooked Akari Akaza; and Chinatsu Yoshikawa, who stumbled upon the others while looking for the Tea Ceremony Club. Together they are the Amusement Club, which has the deceptively simple task of keeping its members entertained.

Along with the Student Council and the odd family member, they strive to enjoy their youth to the fullest. Whether it's a trip to a hot spring or finishing overdue homework, their lives are never dull, and they will always find an excuse to spend time together.

Season 3 of YuruYuri: Happy Go Lily premiered on October 5, 2015.

The members of the Amusement Club are back with more of Kyouko Toshinou's antics, Chinatsu Yoshikawa's schemes, Yui Funami's retorts, and Akari Akaza's small social presence as they strive to make each day as fun as the last! Whether the activity is an arm wrestling contest or making pancakes together, the group of entertainment-seekers are sure to give it their all.

The club members are often joined by their friends in the Student Council, who know how to have a good time as well. While it can get a little chaotic when all eight girls get together, it sure doesn't stop them from meeting up and having fun!
