Thinking that Yamagami was depressed after his defeat by Tenko, Minato takes him out into town to cheer him up. They visit the publisher of a town magazine that features information on sweets, a curry restaurant, and other places, but at the same time, a crisis is approaching the Kusunoki residence.

Tomorrow is the Hojo Festival, which is held once every three years. Minato and Yamagami are playing with spinning tops in the shopping district. At the same time, Harima and the other Onmyoji are cornering a pair of evil exorcists. But then, a mysterious, gigantic abandoned sacred area appears in the sky, and countless evil spirits are unleashed!
