Often, the theme of friendship between Kakashi and an Uchiha character is seen. Despite the differences between Kakashi and the Uchiha, they form strong bonds in fanfics.

And of course, the exploration of the Uchiha clan's secrets and how Sakura gets involved in them.
The theme of sacrifice is often present. In some fanfics, either Kakashi or Naruto is willing to sacrifice for the other, as in 'Sacrifice for a Comrade'.

Both characters are known for their perseverance, and fanfics like 'Persevering Together' highlight how they encourage each other to keep going in the face of difficulties.

A frequent theme is the exploration of their relationship outside of the main Naruto storyline. For example, in some fanfics, they are the main characters in a post - war world where they have to rebuild the village together.

Kakashi starts as Sakura's teacher but as the story progresses, their relationship deepens in a different way.
