It might change the power dynamics. Naruto is a strong character, and without him, his friends may have to step up and develop their skills more quickly to fill the void. This could result in new alliances and rivalries within the group, making the story more complex.
It creates a lot of tension. His friends will be confused and worried about him. This can lead to them trying to find out what's wrong with Naruto, which drives the plot forward as they search for answers.
One possible reason could be that Naruto is afraid of endangering his friends. He has many powerful enemies, and he might think that by staying away from his friends, they won't be targeted. For example, Orochimaru was always after Sasuke, and Naruto might fear that his closeness to Sasuke could put Sasuke in more danger.
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.
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.
When the Kyuubi possesses Naruto, his friends' trust in him is tested. Some, like Shikamaru, might be more cautious and try to keep an eye on Naruto to make sure he doesn't go out of control. Others, like Choji, might be more sympathetic and try to offer Naruto support. This possession changes the dynamics. Naruto might feel isolated as his friends struggle to understand what's going on with him, and it takes time for them to rebuild their normal relationships.
Some of his friends could be inspired. They might see Naruto's departure as a noble act, especially if he's leaving to protect his family. Naruto has always been a source of inspiration, and this could lead them to re - evaluate their own relationships and responsibilities. For instance, Sakura might be motivated to be stronger to support Naruto's family in his absence.
His friends would be overjoyed at first. But then they might start to feel a bit of unease. They've moved on in some ways since his death, and Naruto's resurrection could disrupt that. For example, Sasuke might have to re - evaluate his feelings towards Naruto and their rivalry.
Sakura would be heartbroken. She has deep feelings for Naruto, and his sudden departure would make her feel abandoned. She might initially be angry at him for leaving without saying goodbye but would soon worry about his safety.
The loss of trust could lead to Harry making new alliances. Since he no longer trusts his old friends, he might seek out other characters who he believes are more trustworthy. This could introduce new sub - plots and characters into the story.
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.
