Naruto could become more protective of his friends. With the power of the Kyuubi, he feels a greater sense of responsibility to keep them safe. So he might be more likely to jump in front of danger to shield them. And his friends, in turn, would come to rely on him more in tough situations.
In this fanfiction, Naruto's friends may also start to see him in a new light. They might discover new aspects of his personality that are influenced by the Kyuubi. For instance, he could be more assertive or have a different sense of humor. This could lead to some interesting interactions and a deeper bond between them as they get to know this 'new' Naruto.
His friends might be a bit more cautious around him at first. After all, the Kyuubi is a very powerful and somewhat feared entity. But as they see that Naruto is still himself, they gradually become more accepting. For example, Sasuke might initially be on guard but then realize Naruto is still his friend.
If Naruto and the Kyuubi switch places, his friends might be initially very confused. They are used to Naruto's normal behavior. If the Kyuubi is in Naruto's body, it might be more aggressive or act in ways that seem out of character. His friends would have to figure out what's going on. But if Naruto is in the Kyuubi's place, his friends might start to worry about him more, not knowing what he's experiencing inside the seal.
In this fanfiction, their relationship becomes more of a partnership. Instead of Naruto just using the Kyuubi's power, they work together as brothers. Naruto might start to understand the Kyuubi's feelings and motives better.
Naruto's blindness would surely transform his relationships. His friends would need to adapt. Shikamaru, being the intelligent one, might come up with strategies to help Naruto move around safely. Choji could share his food more often to cheer Naruto up. Ino might use her mind - transfer jutsu in new ways to assist Naruto. His friends would become his eyes in a way, and this new dynamic would deepen their friendships as they all work together to support Naruto in his new situation.
His relationship with Sasuke could improve. With the power of the Kyuubi under his control, Naruto might be able to better understand Sasuke's thirst for power. He could use his new - found strength to show Sasuke that there are other ways to achieve power and protect those he cares about. This might lead to Sasuke finally coming back to Konoha and the two of them becoming true friends again.
In this fanfiction scenario, Sasuke might be jealous of Naruto's new power at first. He has always been competitive with Naruto, and seeing Naruto become something so powerful as the Kyuubi could trigger that jealousy. However, when they face a common enemy together, Sasuke sees that Naruto is struggling to control the Kyuubi's power and needs his help. This could lead to a new level of understanding and friendship between them, as they work together to help Naruto master his new form.
His relationship might become strained at first. His old friends in Konoha might be confused or even angry about his banishment. But some, like Shikamaru or Sakura, might secretly hope for his return and keep in touch with him in secret ways.
At the beginning, it might be a strange and unexpected connection. But as they spend more time together, it turns into a deep emotional bond. Naruto's kind heart might make the fem Kyuubi feel things she's never felt before, and she starts to change for the better.
Naruto's caring changes their relationship in a positive way. At first, the Kyuubi saw Naruto as just a vessel. But as Naruto shows care, the Kyuubi starts to see him as an equal. For instance, it might start to communicate more openly with Naruto, sharing its knowledge of the ninja world.
At first, Naruto might see the Kyuubi as just a source of power. But as he starts to protect it, he realizes it's more of a partner. Their relationship evolves from a simple user - power source dynamic to a deep - seated friendship. He begins to understand the Kyuubi's emotions and past, which further cements their bond.
Well, with his teachers, like Iruka. Iruka might be more hesitant in approaching Naruto at first because of his connection to the Kyuubi. But as he realizes that Naruto is still the same kind - hearted boy, he would become a stronger supporter. As for Kakashi, he could see Naruto as a more complex case. He would need to train Naruto not only in normal ninja skills but also in controlling his Kyuubi - born powers. This would create a different dynamic in their relationship compared to the original story. Naruto's peers in the village might also either shun him more or be in awe of his power, depending on their personalities.
