This happens after the 14th manga. Aoi Akane (Ao-Chan) has died and now nobody can reach the ghosts and spirits in the school. Due to Yashiro and Akane missing Aoi, Teru takes them to the boundary of the Eighth Mystery. They were regularly forgotten compared to the School Mysteries. Y/N was their name. They died during World War II for a reason other than the war, at least that’s what Teru told them. They had a different set of rules to follow compared to the other School Mysteries, aka why they were still reachable while the other School Mysteries weren’t. When they entered their boundary in the school boundary, they were met with fields of flowers.
