READ THIS BEFORE READING THE BOOK... Seitaro, Rin, yutta and Yuka have all survived the swamp and went back to a normal life at their collage where they're all roommates (obviously seitaro and yutta in a bedroom and Rin and Yuka in another) but after the horrors of the swamp rin is plagued with nightmares, but she won't tell anyone about it until one night when it gets to unbearable to keep it to herself and she finds herself telling the least likely person.
