In this chapter, we learn that nozomi and her friend, Yuina, have been chased out of their house by Hiroto's "friend" , and that the path between their school and the mountain has been created. The three of them decide to go to the mountains to find Hiroto, but they'll have to split up into two groups: one to go with Hiroto to the mountain, and the other to go back to the school with Yuina and Hiroto.
