Maybe a fanfiction where they accidentally switch bodies. This would lead to some really funny and also some very emotional moments as they understand each other better from a different perspective.
One idea could be a story where they go on an adventure together to save their world from a dark magic. They face many challenges and in the process, their relationship deepens.
You can start by writing down some character sketches of both Kamisama Kirihito and Nanami. Consider their personalities, their strengths and weaknesses. This will help you write their actions and dialogues more accurately. For example, if Nanami is known for her kindness, show that in how she interacts with others in your story. Then, start with a scene that grabs the reader's attention, like a mysterious event that involves both of them.
A plot idea could be that Nanami accidentally loses her memories and Tomoe has to help her regain them. He would take her to all the places that are important to their relationship, like the shrine where they first met. Along the way, Tomoe would be patient and kind, and as Nanami slowly starts to remember, their bond would become even stronger.
One plot idea could be Jirou and Nanami getting lost in a magical forest together. They'd have to rely on each other to find their way out, facing various magical creatures along the way. This would test their relationship and maybe lead to some romantic moments as they huddle together for safety at night.
Adventure could also be a theme. They could be on a journey together, facing various challenges and obstacles, and relying on each other to get through. This can create exciting and engaging stories as they explore new places and situations.
One idea could be that Nanami's sister discovers a hidden power within herself that is different from Nanami's. Maybe she can communicate with a special type of spirit that no one else can. This could lead to her getting involved in some adventures that are parallel to Nanami's but also unique in their own way.
I'm not sure exactly which kirihito x nanami fanfic to recommend as there are many out there. You could try searching on fanfic websites like Archive of Our Own. They have a large collection of fan - created stories and you might be able to find some great kirihito x nanami ones by using their search function.
A great element to include is the magic that exists in the Kamisama Hajimemashita universe. Nanami learning new spells or Tomoe using his powerful yokai magic in unexpected ways can make the story exciting. You could also have a sub - plot where a rival for Nanami's affections appears, either a human or a yokai. This would create jealousy and tension between Nanami and Tomoe, leading to some passionate moments and a stronger development of their relationship.
A plot could be where Nanami and Tomoe accidentally swap powers for a day. Nanami has to deal with Tomoe's fox powers and all the mischief that comes with it, while Tomoe has to handle being a land god and dealing with human requests. It would be a comical yet also a character - building situation.
Well, there are quite a few interesting ones. For example, 'Tomoe and Nanami: A Magical Journey' takes them on an adventure that deepens their connection. In this fanfiction, the author does a wonderful job of exploring how they rely on each other in different situations. Also, 'Love in the Shrine' is a popular one that delves into the more domestic and affectionate side of their relationship. It's really heart - warming to read about their daily interactions. Then there's 'The Moonlit Promise' which is centered around a special promise between Tomoe and Nanami and how it affects their relationship.
A possible plot could be that Nanami gets into trouble with a powerful spirit and Tomoe has to make a great sacrifice to save her. This sacrifice could be something like giving up a part of his power or his memories. It would show the depth of his love for her.
