Rin (Haruka Fukuhara) decides to do a Christmas camp with a field member. On the day of the camp, Dr. Toba (Yoshimura Tsuchimura), who became an adviser to Nokuru, and Ogaki (Momoko Tanabe) and Inuyama (Yumeina Yanai), arrived at YMCA at Mt. Fuji, which is our campsite earlier than planned. The two enjoy gelato at the Makino Ranch near the campsite. Meanwhile, Rin and Nadeshiko (Yuo Ohara) also arrived and enjoyed a snack with grilled marshmallow sandwiched between chocolate biscuits. And, from Saito (Ayora Shida) who has not arrived yet, a meaningful message arrives at Rin.
