The villagers' attitude towards Naruto could also shift. Some who were always in awe of him might now pity him. But others, like the kids he used to play with, would try to make him remember the good old days. His relationship with the tailed beasts would be really interesting. If he forgets about them, they might try to communicate with him in his mind, which could be a very strange and new experience for Naruto, and it would also be a chance to explore the bond between them in a different way.
With Kakashi, Kakashi would probably be more protective at first. He'd be curious about how Naruto got the cat ears and would keep an eye on him to make sure it doesn't cause any harm to Naruto or the village. Naruto might feel a bit more like he has to prove himself to Kakashi that the cat ears don't make him any less of a ninja.
His relationship with Astrid would become really strained. She'd be heartbroken that he doesn't remember their relationship, and she'd have to work hard to make him fall in love with her all over again. It would be a journey full of mixed emotions for her, from sadness to determination.
Regarding his family, if Dabi forgets his past with them, his family members would be in a difficult position. Endeavor might feel guilty for all the things he's done to Dabi in the past and try to make amends. His siblings, like Fuyumi and Natsuo, would be shocked but also hopeful that they could have a normal relationship with Dabi now. However, as Dabi's memories start to come back, it could lead to a very complex and emotional roller - coaster of relationships.
For his male friends like Shikamaru and Choji, they might initially be a bit awkward around Naruto. But as time passes, they would adapt and might start to treat him more like one of the girls in their group. Naruto's relationship with the older male ninjas like Jiraiya could also change drastically. Jiraiya might not be able to train Naruto in the same way as before and might have to come up with new training methods that are more suitable for Naruto's new form. Naruto's friendships with female characters like Ino could also transform. Ino might take Naruto under her wing and teach him things like how to do proper makeup or how to style his hair in the ninja world.
His relationship with Sasuke might become more competitive. Sasuke, seeing Naruto with this new power of wings, would feel the need to become stronger in his own way. They could have more intense battles or training sessions. With Sakura, she might be initially shocked but then would become more protective of Naruto, fearing that his new wings might attract more dangerous enemies. She could also help him with any medical issues related to the wings if they cause any strain on his body.
His relationship with Sasuke would be very different. Sasuke might be both jealous and intrigued that Naruto now has an Uchiha power. They could become more equal in terms of power, which might lead to a more competitive but also more collaborative friendship. Naruto could also use the Sharingan to understand Sasuke's pain better, seeing the memories of the Uchiha massacre through Sasuke's eyes.
Well, with Sasuke, their relationship would become more of a protective - protectee one. Sasuke, who usually has a rivalry with Naruto, would now feel responsible for protecting this baby Naruto. With Sakura, she would be more motherly towards him. She might be the one constantly fussing over him, making sure he's clean and fed.
His relationship with Sasuke would likely be very different. Since Sasuke has also had experiences with the Rinnegan, they might now have a new level of understanding between them. They could train together to master the powers of the Rinnegan or compare notes on how to use its abilities.
With Kakashi, Naruto's relationship would also shift. Kakashi has had experience with the Sharingan and knows about powerful dojutsu. He would be both amazed and a bit worried about Naruto having the Rinnegan. He might try to mentor Naruto more intensively to make sure he uses it for good and doesn't let the power corrupt him. Naruto would look up to Kakashi even more as he tries to learn about his new power from Kakashi's knowledge.
His relationship with Sasuke would be really interesting. Instead of Sasuke being the only one with the Sharingan, Naruto now has it too. Sasuke might feel a mix of envy and camaraderie. Envy because Naruto has something that was so much a part of his identity, and camaraderie because they now share a powerful ability.
