Well, Hinata would be one of the main characters with a different interaction. She might be more open and confident around Naruto as a girl. Tsunade could also play an important role. She might take Naruto under her wing more as a girl, teaching her things about being a female ninja. And Rock Lee might be even more eager to compete with Naruto as a girl, seeing it as a new and exciting challenge.
Another character could be Hinata. She might be more shy around girl Naruto at first but then they could develop a strong friendship. And the Akatsuki members could also have different interactions with girl Naruto. For example, Itachi might see her as a different kind of threat or an interesting enigma, which could lead to some intense confrontations or unexpected alliances.
Sasuke would definitely be one of the main characters to interact with Naruto. Their relationship has always been complex, and with Naruto as a girl, it could become even more so. Sakura would also interact a lot. She might be both jealous and intrigued by Naruto's new form. Kakashi too, as Naruto's mentor, would have to adjust to this change and guide 'her' in a different way perhaps.
Sasuke would probably interact differently. As a girl, Naruto might be more of an enigma to him. He could be more protective or more conflicted in his feelings towards her. Instead of just seeing her as a rival, there could be a romantic undertone in their interactions.
Sasuke would be really interesting. His relationship with Naruto was always complex, and if Naruto is a girl, it could add a new level of tension or even a different kind of friendship/rivalry. Sakura too. She might have a whole new perspective on Naruto as a girl, and they could form a stronger bond as female comrades. And Kakashi, his reaction to Naruto's transformation could be quite humorous and also a source of guidance for Naruto in this new situation.
Sasuke is a very common character paired with 'girl Naruto'. Their relationship, which was already complex when Naruto was a boy, becomes even more so in these fanfictions. There's often a lot of tension and unspoken feelings between them. Another common pairing is with Naruto and Kakashi. In some stories, Kakashi becomes a mentor in a different way to 'girl Naruto', guiding her through the new challenges she faces as a female ninja.
Obviously, Sasuke would still be a major character she interacts with. Their relationship could be even more complex now that Naruto is a girl. Sakura might also have a different dynamic with Naruto. Instead of seeing her as a rival for Sasuke's attention, they could become closer friends and train together more often.
It's likely that Naruto, now a girl, would be more perceptive. In the male form, he was sometimes oblivious to the subtleties of relationships. As a girl, she might pick up on the unspoken feelings between characters more easily. This could lead to her playing a different role in the group dynamic, perhaps becoming a mediator or a source of emotional stability within the team.
The Third Hokage might also come across Naruto in his girl disguise. He could be either amused or concerned depending on the situation. And some of the female villagers might interact with Naruto. They could either be kind and helpful, thinking he's a new girl in the village, or be a bit catty if they sense something off about this new 'girl'.
The Anbu would probably be very guarded in his interactions at first. He is used to secrecy and stealth. But the girl, with her Naruto - inspired enthusiasm, might break through his cold exterior. For example, she could start talking about her favorite Naruto characters and their values, which might make the Anbu reflect on his own actions.
If Naruto becomes a girl, her character development would be quite distinct. She could start to view the world from a more empathetic perspective. Her experiences as a girl could make her more aware of the inequalities in the ninja world, especially those related to gender. This new awareness could fuel her drive to make changes. For instance, she might start campaigns or initiatives to give female ninjas more equal opportunities. She would also have to adapt to a different physicality. As a girl, her body might be different in terms of strength and agility, which would force her to develop new fighting styles and strategies, thus leading to a different kind of character growth.
