Satori goes to the surface to ask Reimu’s help in understanding the story and lifestyle of the surface world.

Kurihara Ichito is a young, hardworking doctor who works at a Nagano clinic. He is so busy with his work that he hardly ever gets to see his wife, Haruna, who is a professional mountain photographer. The clinic is a lively place, where he interacts with patients and his colleagues. The kind-hearted, but stern, nurse Naomi helps through the day. He also works with his friend from school, Jirou, who has a crush on the cute nurse Mizunashi. There's also an old veteran doctor, Furugitsune, who always looks a little unwell. Is this stressful, hectic lifestyle really the path to the life of Ichito's dreams, or will he end up like Furugitsune?

The story is told by Albert N. Wilmarth, an instructor of literature at Miskatonic University in Arkham, Massachusetts. When local newspapers report strange things seen floating in rivers during a historic Vermont flood, Wilmarth becomes embroiled in a controversy about the reality and significance of the sightings, though he sides with the skeptics, blaming old legends about monsters living in uninhabited hills who abduct people who venture too close to their territory.
