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.
When Tomoe reverted to being a wild fox to save Nanami, he undid his contract as her familiar. And now, he takes this opportunity to reconsider whether he wants to go back to Nanami or not.
Izanami imprisons Kirihito and refuses to allow Nanami to return to the surface with him. Nanami must decide how much she believes in her own powers and what she is willing to risk to save him.
