Titre original : Christmas!
Ui remembers how Yui once attempted to give her a white Christmas by sticking pillow stuffing on the tree outside. Ritsu decides to hold a Christmas party for the club, and while her initial plans of holding it at Tsumugi's house fail, they eventually decide to have it at Yui's house, also inviting her friend, Nodoka Manabe. They also decide to do a gift exchange, and go shopping for various gifts. Ui prepares a lovely Christmas dinner for the group, which gets a little out of hand when Sawako shows up out of no where. During the gift exchange, Yui and Ui give each other some warm things for the winter. After the rest of the group leaves, snow falls and Yui and Ui decide to sleep together, although Yui ends up hogging the sheets. In the New Year, the club decides to go to the shrine to make their New Year wishes.
