## Description
Onibushichou is a rural town in a basin surrounded by mountains, close to Sea of Japan. Further in from there is the even more rural village of Koubou.

Today, April 6, 2023, is the day of the entrance ceremony for Koubou’s only school, Keijou Academy High School. At this school, which is celebrating its 10th anniversary and is understood by no one as to why it was opened in such an underpopulated area, a new student arrives. His name is En Ayakari.

“Go back to Koubou.”

As his mother’s dying wish, he moved from the city to Koubou, where he has memories of living as a child. While there was no meaning or significance to coming back now, new and familiar encounters drag him into the restless “Seven Wonders of the Academy” selection swamp. At Keijou Academy High School, the seven wonders of the academy did not yet exist.

In a land where demons lie, a strange bond is formed. This is a story woven by humans and mountain demons (Sudama).
