Satoru and Saki have been split up from the rest of the group and captured by the outside Monster Rat group.

Two years have passed since the camping incident and the relationship between the friends has changed dramatically.

Many years have passed; Saki and Satoru have grown and moved their separate ways. But recent actions within the monster rat community have brought them back together.
