Unable to exorcise the miasma encroaching on the shrine, Nanami believes she is useless and leaves. Finding her gone, Tomoe and Mizuki go searching for her, leaving the shrine and the miasma to Onikiri and Kotetsu.

As the land god of the Mikage Shrine, Nanami is invited to the annual gathering of the gods in Izumo, but on the one condition that she must pass a test administered by Otohiko.
