One common theme is friendship. Writers often explore how Himawari and Kawaki, who come from different backgrounds, form a bond of friendship. Another theme is growth. They both grow as characters, learning from each other.
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 common theme is growth. Both Himawari and Kawaki are often depicted as growing both as individuals and in their relationship. Another theme is acceptance. Since they come from different backgrounds, fanfictions usually show how they accept each other's differences.
Yes, there are many. Some fanfics might focus on their growing relationship, like how they gradually understand and support each other. For example, in one fanfic, Kawaki and Himawari start as classmates who don't get along at first. But as they face challenges together in the ninja academy, they begin to respect and care for one another.
Kawaki makes his appearance in Boruto manga at a specific point, but I can't recall exactly. You might want to check the official manga sources for the precise chapter.
One great Himawari and Kawaki fanfiction is 'The Bond of New Beginnings'. It focuses on how they start to form an unexpected friendship in the village, with Himawari's kindness breaking through Kawaki's tough exterior.
It's also about the potential for character growth. In fanfics, we can see how they influence each other. Himawari might help Kawaki open up more, and Kawaki could teach Himawari about the harsher side of life. This mutual growth and the exploration of their relationship make the fanfics popular.
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.
Kawaki could be developed by showing his softer side when he is around Himawari. For example, he might start to open up more about his past traumas. Himawari, on the other hand, can be shown to become more confident in her abilities with Kawaki's support.
