The God is Kidnapped.Nanami saves a white snake from being assaulted by her classmates at school, but it leaves a mark of betrothal on her wrist when she lets it outside. When Tomoe finds out, he goes to school with her because he does not want her to be kidnapped. After finishing the shift to fill up the class daybook, Nanami goes off first because Tomoe fell asleep, but she is kidnapped by Mizuki, the white snake who is actually a yokai and former familiar, and takes her to his shrine in hopes of marrying her. After she realizes that she cannot leave the premises of the shrine, she decides to rest there, hoping that Tomoe will rescue her. Nanami later learns that Yonomori Mitsuha, the Water God of the shrine, died years ago. Nanami refuses to stay with Mizuki, but when Mizuki tries to make a move on her, Tomoe comes to rescue her and burns down the shrine. However, Nanami stops Tomoe from burning down the Yonomori's plum tree, which is precious to Mizuki. Before Nanami and Tomoe head back to their shrine, Nanami promises to see Mizuki again when he feels lonely.
