Christmas is a magical time that makes people go a little crazy. On the day of Christmas Eve, Yufuin makes the shockingly uncharacteristic suggestion that that they hold a Christmas party. Gora joins the Christmas party at Kurotama Bath, and even more unexpected visitors show up, throwing the party into chaos! A one-night-only miracle of love and confusion begins!
