Santa, Miyu and Kanata go to an onsen, or hot spring, at the top of the mountain. However, Miyu did not know that they have to dig up their own onsen. A monkey seals Miyu's bag so she chases after it to get it. She accidentally falls over the cliff and hurts her arm. Kanata jumps off after her.They share memories while they are waiting for Santa to get help, when Chris shows up.
