Some of his friends could be more accepting than others. Choji might be a bit hesitant at first but still be friendly towards Naruto. However, Ino might be more cautious, especially if she thinks Naruto's vampire side could pose a danger to their safety. But as Naruto proves himself, he could gradually regain their trust. His relationship with Sasuke could also be interesting. Sasuke might see Naruto's vampire side as a new power to be reckoned with and either be jealous or see it as a potential ally in their future battles.
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 relationships might be less intense in some ways. Since he has a family, he might not be as clingy to his friends like Sasuke. For example, he wouldn't be as desperate to bring Sasuke back because he has his parents' support at home.
Well, Naruto being cold could really put a strain on his friendships. His friends like Sakura and Kakashi would be concerned. Sakura might try to use her medical skills to check if there's something physically wrong with him. And Kakashi could attempt to have heart - to - heart conversations to break through that cold exterior. Since Naruto is usually so warm - hearted, this change would be quite a shock to them all.
It might actually strengthen his relationships in some ways. His friends could see him as an even more powerful ally. Naruto, with these new powers, could protect them better. Sakura, for instance, would feel safer around him and this could lead to a deeper bond of trust between them.
Some friends might feel betrayed. If they are very clan - oriented, they could see Naruto's leaving as a sign that he doesn't value the clan and by extension, their friendship. However, his true friends like Sasuke or Sakura might understand his reasons. Sasuke, who has his own issues with his clan, might be more empathetic. Sakura, who has seen Naruto's determination, could support his decision in the long run.
On the other hand, some of his closer friends like Sakura could be more understanding. She might try to talk to Naruto and find out his reasons. This could actually strengthen their bond as she shows her support for him. However, among the wider group of his peers, there could be rumors and misunderstandings. Some might think Naruto is being cowardly or irresponsible, which could isolate him to some extent. But those who truly know Naruto would know that he must have a valid reason for his refusal, and they would wait for him to open up about it.
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.
Naruto's ability to use chakra would be a major factor. He could use it to demonstrate amazing feats to the students, like creating clones to help with group activities or using his Rasengan in a controlled way to show the power of concentration. His ninja speed would also make him a very active teacher, able to be everywhere in the classroom or training ground quickly.
Well, his friends might initially feel betrayed. For example, Sasuke might be angry that Naruto left without consulting him, considering their complex relationship. However, some friends like Shikamaru might understand Naruto's reasons deep down and wait for his return. His female friends like Sakura might worry about his safety constantly.
His friends might be worried about him. The search for the Master Sword could be dangerous, and they might fear for his safety.
