His friends might be initially shocked. Sakura could tease him about it at first but then grow to like the new look. Sasuke might be indifferent on the surface but secretly find it interesting. His enemies might underestimate him, thinking he's become more of a softie with the long hair, but then be surprised by his unchanged combat skills.
In this fanfiction scenario, Naruto's long hair could have a significant impact on his relationships. His female admirers might increase in number, which could make some of his male friends a bit jealous. His bond with Jiraiya could also be affected. Jiraiya might see the long - haired Naruto as more of a mature and powerful ninja, and start to treat him more as an equal rather than a student. At the same time, some of the older ninja in the village who are more traditional might be disapproving of his new look, which could create some tension in his relationships with them. However, Naruto's positive and determined attitude would likely help him overcome any negative reactions and maintain his strong relationships with those who truly matter to him.
His long hair might make Sakura see him in a different light. Maybe she starts to notice his more mature side with the long hair and becomes more attracted to him. It could also change his relationship with Sasuke. Sasuke might initially mock his new look but later come to respect the power that seems to be associated with Naruto's long hair.
His relationship with Sasuke might be different. Sasuke could be more intrigued by Naruto's new look and the possible mystery behind the black hair. It could either create more tension or bring them closer as they try to figure out what's going on.
In terms of his relationship with the villagers, those who once bullied him for being an orphan and having a different look (with his blond hair) might be even more hostile if his red hair makes him stand out more. However, there could also be some villagers who see his red hair as a sign of something special and start to respect him more, which could lead to a shift in how Naruto views the village and his place in it.
His relationship with Sakura might change. Sakura could be initially shocked by his new look and it might make her see him in a different light. Maybe she starts to notice him more as a person rather than just her friend. For example, she might become more curious about what happened to cause the change and in the process, grow closer to him.
Naruto's relationship with his enemies would surely be affected. Enemies might target him more if they think his red hair is a sign of a new power they can steal or a weakness they can exploit. On the other hand, some enemies might be more hesitant to attack him, fearing that the red hair is a sign of a new and unknown strength. His relationships within the ninja world in general would be in flux, as everyone tries to figure out what this red - haired Naruto means for the balance of power.
His relationship with Sakura might change. She could be more intrigued by his new look and start to see him in a different light, not just as the annoying kid. With Sasuke, Sasuke might be more jealous as Naruto's blue hair makes him even more unique and gets more attention.
If Naruto were not human, his relationships would likely be very different. For example, his relationship with Sasuke might be more strained. Sasuke, who is very focused on power and revenge, might see Naruto as a greater threat if he's not human. He could view Naruto's non - human abilities as something to envy or fear. With Sakura, she might be more hesitant around Naruto. Instead of her initial crush, she could be more cautious, not knowing what Naruto is truly capable of.
With Sakura, she might be initially afraid of Naruto's demon form. But as she realizes that Naruto is still the same person inside, she could become more protective of him and help him control his powers. Their friendship could deepen in a different way compared to the original story.
Naruto's skin might start to glow with a strange energy, similar to how Kaguya seemed to have an otherworldly aura. His eyes could change color to something more like Kaguya's, perhaps a deeper, more mysterious hue. And his clothing might even transform to be more in line with Kaguya's style, as if the absorption of her power also influenced his physical form in that way. He might also grow taller or more muscular as a result of the new power coursing through his body.
Well, Naruto's hair to his waist would be a significant change. His hair has always been a prominent part of his appearance. Now with it being so long, it could be styled in different ways. He might braid it on the sides or let it flow freely. His headband would look different too, perhaps sitting on top of his long hair rather than directly on his forehead. Also, his long hair could be a symbol of his growth, not just physically but also in terms of his power and journey. People in the village might view him with a new level of respect or curiosity just because of his changed appearance.
