Naruto might become more cautious. Usually, he is bold and upfront, but with a mask, he could be more aware of his hidden identity and act more stealthily. Hinata, who is already shy, might use the mask as a form of protection. It could give her more confidence to be bolder in her actions towards Naruto, like speaking her mind more freely.
In the 'naruto has a mask fanfiction', it might be that Naruto finds the mask himself. He could stumble upon it during one of his adventures, perhaps in an ancient ruin or a hidden cave.

His enemies, too. They might realize that Naruto is not as straightforward as they thought. If he shows a more cunning side by dropping the mask, they would have to adjust their battle strategies. For example, Orochimaru might find Naruto a more formidable opponent than he initially believed.

For example, her Byakugan abilities might be exploited in unique ways that make her seem like a strategic weapon for a side or a cause. But in the canon Naruto story, she is a character with her own agency and not really a weapon.
