His friends might become more important to him. Since he is no longer living with his parents, he may rely more on his friends for support and companionship. For instance, he might start spending more time with his best friend, sharing his new living experiences and problems.
It could strain his relationship with his family members at first. His parents may be hurt or angry that he moved out. But as the story progresses, they might come to understand his reasons and the relationship could be mended. On the other hand, his relationship with siblings could also change. If he has a younger sibling, the younger one might miss him a lot.
It could strain his relationship with Sirius. Sirius was his father's best friend, and if Harry doesn't forgive his parents, Sirius might feel caught in the middle. He might try to defend them, which could lead to arguments between him and Harry. For example, Sirius might talk about how brave his father was, but Harry, in his state of non - forgiveness, might not want to hear it.
It might make his relationship with his friends a bit strained. For example, Hermione and Ron might not understand his anger at first and try to convince him that his parents were heroes. This could lead to some arguments between them.
Well, in such fanfiction, Harry's neglect by his parents can cause him to have a deep - seated fear of abandonment in his friendships. This could lead to him constantly testing his friends' loyalty. On the other hand, his friends, if they are true friends, will be more patient with him and try to show him unconditional love, which in turn can strengthen their relationships in the long run.
It can make him more self - reliant. Without the support of his family, Naruto has to learn to take care of himself, which can lead to him becoming stronger both physically and mentally. He'll have to figure out how to manage his finances, find a place to live, and cook for himself, all of which are new challenges that can shape him into a more independent person.
It might make him more distant from his friends at first. He could be so consumed by his anger towards his parents that he withdraws from his usual social circle. For example, he might avoid spending time with Sasuke or Sakura because he is too preoccupied with his feelings about his parents.
His friends usually find it quite amusing. Ron and Hermione might at first be a bit exasperated but then they end up enjoying the chaos. For example, when Harry pranks the Slytherins, Ron might be initially worried about getting in trouble but then laugh when they see the Slytherins' reactions. Hermione, on the other hand, might scold Harry but secretly be entertained.
With his friends, it could be a mixed bag. Some friends might support him wholeheartedly, which could strengthen their bond. However, others may be cautious. For instance, if a friend has a close relationship with a particular god, Percy's hatred could cause tension. Also, his attitude towards the gods might make it difficult for him to interact with godly allies or enemies. He may be more hostile towards them than necessary, which could change the dynamics of battles or negotiations.
His hatred might make him more distant from the other demigods who still have some respect or hope for Olympus. They may not understand his extreme feelings and this could create tension.
The black chakra could make other characters view Naruto with suspicion. His friends might be worried that this new power is corrupting him, which could strain their relationships. For instance, Sasuke might see it as a sign that Naruto is becoming more like the enemies they've fought.
With the teachers, like Dumbledore, he might be treated differently. Dumbledore might see this transformation as an opportunity for Harry to learn new things about the wizarding world from a different perspective. And some of the more traditional teachers might have different expectations of Harry's behavior in class now that he is a girl.
