Pony Canyon describes the synopsis of The Mononoke Lecture Logs of Chuzenji-sensei as:
This story takes place before the exorcist Kyogokudo opened up a used bookstore… Our setting is in Tokyo in 1948, just right after the war.
Kanna Kusakabe had just become a second-year at a high school when she meets the new language teacher, Akihiko Chuzenji. Mysterious supernatural things keep happening around Kanna. Once again today, Kanna is going to open the doors to the library prep room to seek help from the surly Chuzenji-sensei who is waiting inside.
A high school supernatural mystery featuring the unlikely duo between a teacher and a high school girl is about to begin!
