Who are the main characters likely to interact with Naruto in the 'Naruto apprentice of Yugao fanfiction'?

Obviously, Naruto and Hayate would be the main characters. Naruto is the protagonist who will be learning from Hayate.

Obviously, Naruto and Hiruzen would be the main characters. Naruto as the apprentice and Hiruzen as the mentor.

Obviously, Naruto and Anko would be the main characters. Naruto, the energetic and determined ninja, and Anko, the somewhat eccentric and skilled kunoichi.

Kakashi could also play a role. He has been Naruto's mentor for a long time. So, he might have some mixed feelings about Itachi adopting Naruto. He could be suspicious of Itachi's motives at first but then gradually come to understand Itachi's positive influence on Naruto. Their interactions could be really fun to read about, especially when Kakashi tries to give Itachi some advice on how to handle Naruto's wild nature.

Obviously, Nagato himself would be the main character interacting with Naruto. He would be like a mentor or a guardian figure in Naruto's life.

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.

The Raikage, Ay, would also interact with Naruto. He might be hesitant at first about Killer Bee adopting Naruto, worried about potential problems. But as Naruto shows his strength and loyalty, Ay could start to see Naruto as an asset to the village.

They could be worried about Naruto living in a different village but also be proud of his new experiences.

Definitely Shikamaru's friends like Choji. Naruto in Shikamaru's body would still have that bond with Choji, but it would be different.
