First, focus on her means of communication. Since she's mute, you could have her use sign language, written notes, or even telepathy if you want to add a fantasy element. For example, she could use her kunai to write messages in the dirt during a battle. Then, think about how her muteness affects her relationships. Maybe Naruto is extra protective of her because he feels she's more vulnerable. Also, give her unique skills. Like she could be an expert at stealth because she has learned to be quiet from a young age.
In 'naruto mute fanfiction', the theme of self - discovery is quite common.

One aspect that makes it unique is the way it challenges the typical ninja archetype. Normally, ninjas in Naruto are known for their powerful jutsu and sharp tongues. But a mute ninja flips this on its head. It forces the writer to think outside the box in terms of how the character will fight, how they will form alliances, and how they will contribute to the overall story. It also allows for a different exploration of the Naruto world, as the mute ninja may interact with certain elements of the world in a way that a speaking ninja wouldn't.
