It could make their peers jealous. For example, characters like Shikamaru might feel that Naruto and Sasuke are getting special treatment. But for their mentors, it could strengthen the bond. Kakashi might have more faith in them and train them more intensively. And for Sakura, she might be both proud and a bit envious of Sasuke's early graduation.
As for the other Konoha 11 members, they might initially be skeptical. But as they see how Sasuke is changing for the better under Naruto's adoption, they start to include him more in group activities. They come to respect Naruto's decision and see Sasuke in a new light, which gradually strengthens the overall unity among them.
The training could strengthen their bond. They have to work together to teach the young one, so they need to communicate better. For example, Naruto might suggest a more fun - filled training method, and Sasuke might initially oppose it but then see the value in it. This back - and - forth can make them understand each other's perspectives more, just like in their own growth as friends.
For Sakura, it could be a huge emotional blow. She might feel abandoned and be motivated to become stronger herself to bring them back. Also, she might have to step up in their absence and take on more responsibilities in the village.
It could make Sasuke more protective of Naruto. Sasuke has always had a complex relationship with Naruto, and seeing him lose an arm would stir up some deep emotions. He might feel guilty, especially if he was somehow involved in the incident that cost Naruto his arm. This could lead to Sasuke staying closer to Naruto and being more open about his feelings.
In fanfiction, the 'hot sauce punch' might be a turning point. It could make Sasuke realize that Naruto still has that goofy side and it might soften his cold exterior. On the other hand, if Naruto uses it out of anger, it could deepen the rift between them. For example, if Sasuke has just made a decision that Naruto strongly opposes, the punch could be a physical manifestation of his frustration.
In some fanfictions, the curse mark can initially drive a wedge between Naruto and Sasuke. Sasuke might become more withdrawn and brooding due to the power and dark influence of the curse mark. Naruto, on the other hand, would be worried about his friend but might not fully understand what Sasuke is going through. This could lead to some misunderstandings and arguments between them as Naruto tries to reach out while Sasuke pushes him away.
Iruka - sensei would be a likely candidate. He has always seen the potential in Naruto and has been like a father figure to him in some ways. He might advocate for Naruto's early graduation because he believes Naruto has what it takes. Also, Kakashi - sensei could be another one. He has seen Naruto's growth and determination during their training sessions and might think that Naruto is ready to move on to the next level earlier than others.
For Naruto, it would be a difficult situation. Naruto has always been Sasuke's friend and Sakura is also his teammate. He would likely try to mediate between them at first. But if the divorce goes through, it would put a strain on his relationships with both of them. He might feel a sense of failure as he always hoped for their happiness together.
Well, with Minato alive, Naruto would have a stronger family support system. This would likely make Naruto less eager to prove himself through Sasuke. And for Sasuke, seeing Naruto having a complete family with Minato might stir some complex emotions in him. Maybe envy at first, but later it could lead to him being more open to Naruto's friendship. Minato could also act as a mediator between the two, guiding them to understand each other's pain and dreams better, thus forging a stronger bond between them.
For the new generation of ninja like Boruto and his friends, they might view Sakura's overprotectiveness as strange. Boruto in particular, who has his own views on Naruto, might not understand why Sakura is so over the top in protecting Naruto. This could lead to some misunderstandings between the generations.
