Yuru Yuri,

Akari Akaza, Chinatsu Yoshikawa, Kyouko Toshinou, and Yui Funami get back together to mark a special occasion. After tossing around some characteristically odd ideas for how to celebrate, they settle on throwing a party in the Amusement Club room.

With a little assistance from their Student Council friends, preparations get underway—complete with a surprise meant for someone important. Along the way, their familiar chemistry and distinct quirks keep the planning lively as they work toward a fun, memorable day.
