One common theme is the growth of their relationship. Since they are Genin, it often focuses on the early stages of their feelings for each other. Another theme could be their training together. They both are ninjas in training, so fanfics might show them helping each other improve their skills while also developing their relationship.
Often, there's the theme of Hinata's shyness and Naruto's obliviousness. In many Genin Naruto x Hinata fanfics, Hinata has a hard time expressing her feelings to Naruto, who is often too focused on becoming Hokage or other things to notice her feelings right away. This creates a lot of cute and sometimes angsty situations as their relationship slowly develops. Additionally, the theme of them facing challenges together as a team or as friends is also quite common.
Overcoming challenges is also a typical theme. Genin face many difficulties like tough missions, rivalries with other genin teams. Fanfics explore how they deal with these challenges, like Naruto facing off against stronger opponents and finding ways to win through his determination and unique skills.
One common theme is friendship. The genin teams in Naruto are known for their strong bonds, and fanfics often explore how these friendships develop and are tested. Another theme is growth. They start as inexperienced genin and grow into stronger shinobi.
Love triangles also appear quite often. Given Hinata's feelings for Naruto and the complex relationship between Naruto and Sasuke, writers play around with the idea of how these relationships can develop in different ways, adding a touch of romance and drama to the stories.
One common theme is self - discovery. Both Hinata and Naruto often go through a journey of understanding themselves better within the context of their relationship. Another theme is acceptance, as Naruto has to accept Hinata's different form in these fanfics.
Love and relationship are common themes. Since it's about Naruto as Hokage and Hinata, their love story is central. It often shows how they support each other, like Hinata standing by Naruto in his Hokage duties.
Another common theme is family. They might explore how Naruto and Hinata start their own family, or how their relationship affects the families around them in Konoha. For example, how Hinata's family reacts to her relationship with Naruto.
One common theme is possessiveness. Since Hinata is a yandere in these fanfics, she is extremely possessive of Naruto. She doesn't want to share him with anyone else, whether it's his friends or other potential love interests.
One common theme is friendship. Since they are both genin, their relationship often starts as a friendship and may develop into something more. Another theme is growth. They are learning and growing as ninjas, so that's often explored in these fanfictions.
Also, the theme of friendship within the genin group might be important. Naruto and Hinata's relationship could be contrasted with their relationships with other genin like Sasuke and Sakura. It could show how their bond is different and special, perhaps with some humorous or heartwarming interactions among the whole group while still highlighting the Naruto - Hinata dynamic.
Some fanfics focus on the idea of alternate universes. For example, what if Naruto had noticed Hinata's feelings earlier? Or what if Hinata was the one to save Naruto from a difficult situation instead of the other way around? These alternate scenarios allow for different takes on their relationship and add an interesting twist to the traditional Hinata x Naruto story.
