Rin oversleeps and is rushing to her campsite when she encounters a roadblock. Upon being told by Chiaki that it may have been left there and never moved, she proceeds and reaches the site, where she struggles to set up due to the windy conditions. Nadeshiko, Chiaki, and Aoi plan their Christmas camping trip and invite Rin, who initially refuses before being convinced by Ena to accept. Toba, the new teacher, is unintentionally lured into becoming the Outdoor Activities Club advisor and is invited to the Christmas camp. Upon hearing Toba mention bringing beer along, Nadeshiko realizes she was the drunk sister from the Lake Shibire trip.
