Kamisama hajimemashita - Season 1 (2012)

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.

Nanami experiments a little with her divine powers while she struggles to define exactly how she feels about Tomoe. And Kurama, being the yokai who has more experience with humans, offers some words of advice to Tomoe.

Summer break is here and Nanami goes to the beach with her friends to take her mind off her broken heart. Trouble ensues when Tomoe accompanies her and goes into the ocean against his better judgment.

In her quest to recover the stolen Dragon King's right eye and return it to him in exchange for Tomoe's freedom, Nanami travels back in time and gets a glimpse of Tomoe's past.

Flashing back to the past, some of what Tomoe went through with Mikage is revealed. And returning to the present for the second part, Nanami gets dragged off to a mixer with her friends.

Mizuki ventures into the city alone to learn the secret to making it in human society like the super popular pop star Kurama. And Nanami drags Tomoe off on a date to the amusement park.

Nanami decides to hold an autumn festival at the shrine to let the locals know that it's not abandoned or haunted. But as she prepares for the festival, Otohiko comes along to throw a wrench into things.

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.
