A popular theme is Himawari's unique abilities. Since she has strong potential, fanfics explore how Boruto helps her understand and use her powers. Also, the theme of friendship within the context of their sibling bond is often seen. They might have friends in common or help each other make new friends in the ninja world.
The theme of family also plays a big part. Many fanfics involve their parents, Naruto and Hinata, and how the family dynamic affects Boruto and Himawari. Adventure is another common theme. They might go on a journey to discover a new ninja technique or to help a neighboring village. It makes for exciting reading.
Boruto could be developed by showing his growth in responsibility. For example, in the fanfic, he could take on the task of teaching Himawari a new jutsu. This would not only show his skills but also his patience. Himawari, on the other hand, could be developed by showing her becoming more independent. Maybe she decides to go on a small mission on her own to prove herself to Boruto.
One great 'Boruto and Himawari fanfic' is 'Sibling Adventures'. It shows their daily life in Konoha, with Boruto teaching Himawari some new ninja techniques in a really cute way. They also have some small adventures together around the village, like finding a lost pet. Another one is 'Himawari's Growth' which focuses on Himawari's development as a ninja under Boruto's guidance. It's really inspiring to see their bond strengthen as she learns.
One great idea for a Boruto and Himawari fanfic is a story where they go on a journey outside the village. They might encounter new types of ninjas or strange creatures. Himawari could be the one to sense danger with her Byakugan first, and Boruto would be ready to fight. It would show their growth as ninjas and also their bond as siblings.
Perhaps in the fanfic, Boruto and Himawari are involved in a festival in the village. They enter a contest together, like a ninja skills show - off. Boruto is a bit overconfident at first, but Himawari keeps him grounded. In the end, they learn more about each other and their combined strength as siblings.
Another theme is Himawari's growth as a ninja. Writers often explore how she trains, faces challenges, and becomes stronger, sometimes with Naruto's help or just by following in his footsteps. For example, there are fanfictions where she has to deal with difficult opponents on her own, which shows her character development.
One positive theme could be their adventures together. For example, they could go on a journey to explore a new part of the ninja world, facing challenges and growing stronger as siblings. They might encounter new types of ninjutsu or unique creatures, and their bond would be strengthened through these experiences.
Well, perhaps a story where Boruto and Himawari accidentally swap their abilities for a day. Boruto has to deal with Himawari's gentle nature and her unique skills, while Himawari has to adapt to Boruto's more energetic and combat - oriented skills. This could lead to some really funny and heartwarming moments between them as they learn more about each other.
Websites like FanFiction.net and Archive of Our Own (AO3) are great places to start. They have a large collection of fanfics related to Naruto and his family.
There are many fanfics that explore the relationship between Naruto and Hinata further. Some might focus on their daily family life with Boruto and Himawari, like how they deal with Boruto's rebellious phase while still maintaining a loving family environment.
The relationship can be shown as a strong sibling bond. For example, Boruto could be protective of Himawari when she is in danger during a mission. Or Himawari could be the one to cheer Boruto up when he is feeling down about his ninja training.
