Here is a short synopsis of the anime as provided by NIS America:
Right after starting middle school, Akari Akaza joins the Amusement club, whose only other members are her two childhood friends, Kyoko Toshino and Yui Funami. Chinatsu Yoshikawa, Akari's classmate, becomes the fourth member after falling head over heels for Yui. The Amusement club meets at the abandoned tea ceremony room and has no clear purpose, leaving the girls to do whatever they want. More often than not, Kyoko stirs up some wild scheme to get everyone in trouble, all as a means to pass the time and experience the ideal middle school life!
As usual the set comes with the 2 Blu-ray disks and a full color 32 page artbook all inside a hard cover slip case. The second set will become available on January 7th 2014. You can preorder it from all of the sites mentioned above. Stay tuned for our in-depth look at both sets!
