Abandoned by her father, Nanami finds herself homeless when she meets a man who offers his own home to her. His home turns out to be a shrine where his supernatural household awaits the return of their lord and master after a 20-year absence.

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.

Tomoe gets some insight into Nanami's childhood. And they finally get through the torii gates to see the Year God.
