A Sound Novel adaptation of a Web Novel.
The city of ancient ghost tales, Kodamamachi. In the art club of the Kodama north middle school, a group of local girls gather every day to talk about their shared interest: ghost stories.
They still don't know that by doing so they're slowly breaking the lock of something that was sealed deep within the school.
On that faithful May, two club members, Karasugai Itsuka and Kuroume Maki, have a sudden encounter with a real youkai who calls himself Kanon. He says their ghost stories weakened the seal of the "Great Spirit Way", and he commands them to take responsibility for it.
In order to seal it back, they need to solve the mysterious occurrences that start happening around the school.
