In terms of relationships, Naruto's transformation into a vampire would have a huge impact. His friends in Team 7 would be thrown into confusion. Sakura might try to find a way to 'cure' him at first, which could strain their relationship. Sasuke might see Naruto's new state as a sign of weakness or an opportunity to gain power. Naruto's relationship with the Hokage, whether it's Tsunade or someone else, would also change. The Hokage would have to decide how to handle a vampire - ninja in the village, whether to keep it a secret or make it public. And Naruto would have to deal with the emotional turmoil of potentially losing the trust and closeness of those he cares about.
His relationship with his sensei, Kakashi, would change significantly. Kakashi would be more cautious around Naruto, not fully understanding the implications of his new vampire state. At the same time, he would try to guide Naruto in controlling his new powers. Naruto would look to Kakashi for help but also feel a sense of isolation as he realizes he's different from the other ninjas. And his friendships with the other Konoha 11 would be strained. They might be afraid of him, or he might push them away to protect them.
His relationship with Sakura would be very different. Instead of the old friendship/romantic tension, Sakura might be initially afraid of him as a vampire. She would have to overcome her fear and see that Naruto is still the same person inside. His relationship with Sasuke could also be strained. Sasuke might see Naruto's transformation as a sign of weakness or a new threat.
In a Percy Jackson vampire fanfiction, his relationships would be transformed. His friends at Camp Half - Blood would likely be very wary of him. They've fought against monsters, and now Percy is something that was once considered a monster. His relationship with his mother would be difficult. She'd have to accept that her son is now a vampire. And with Annabeth, it would be a complex situation. Their love would be tested as she tries to understand and accept this new version of Percy.
His relationship with his human friends would definitely change. They might be scared of him at first, especially if he shows signs of his new vampire nature like a craving for blood. Some friends might try to distance themselves from him, while others might be more understanding and try to help him control his new urges.
His relationships would change drastically. His work colleagues, for example, would notice his different behavior. He might start to work at night and avoid daylight. His relationships with other vampires could also be complex. He could form alliances with some vampires who are more sympathetic to his situation, while others might see him as an outsider. In his social circle, he would become a mystery to those who knew him before, and he would have to find new ways to interact with people.
His relationship with Ron and Hermione would be completely different. They might not recognize him at first when he is Daphne. And once they do, they would have to adjust to interacting with him in a female form. With Ron, there could be some awkwardness at first. Hermione, on the other hand, might be more intrigued and try to help him figure out how to change back. His relationships with his Slytherin classmates as Daphne would also be new. He would have to fit into Daphne's social circle and deal with the prejudices and alliances within Slytherin.
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.
His relationship with Sasuke would likely be very different. Sasuke might initially be shocked and confused. They would have to re - evaluate their friendship in a new light, with Naruto now in a female form.
His relationship with Sasuke would be really interesting. Since Sasuke has his own complex connection to the Uchiha clan and Madara, Naruto becoming a Madara fan could either bring them closer together in understanding the Uchiha's past or drive them further apart if Sasuke doesn't agree with Naruto's new - found admiration. Maybe Naruto would start to push Sasuke towards a more 'Madara - like' view of power and revenge.
