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.

Nanami discovers that Kurama, a famous pop star, has transferred to her high school, which spurs her to return to school. However, as a weak land god, her life may be at risk if she wanders outside the shrine alone.

The land under Mikage Shrine's protection includes Isara Swamp and Himemiko, its guardian mistress, comes to pay her respects to the new land god. And Nanami's divine matchmaking powers are put to the test for the first time.

Nanami saves a pretty white snake at school and for her trouble, she becomes marked as the snake's intended. Tomoe transfers into Nanami's class to protect her, but the snake comes for her anyway.

Narukami, god of thunder, has always wanted Tomoe as a familiar for herself. Now that the god he serves is Nanami, a human girl, Narukami sees her chance to take away Nanami's godhood and make Tomoe hers.

Nanami stays home with a cold while Tomoe goes to school disguised as her in order to keep her attendance rate from slipping. Mizuki takes advantage of Tomoe's absence to pay Nanami a visit.
