It could start with Naruto getting a mysterious message or a vision that tells him he and Sasuke need to leave together for the greater good. He then goes to find Sasuke and convinces him to come along.
The fanfic could begin with a major event in the ninja world that makes both Naruto and Sasuke realize that they can't stay in the villages any longer. For example, a new evil force emerges that the current ninja system can't handle. So they decide to leave together to find a solution on their own.
Their relationship would go through several stages. Initially, there would be a sense of unease as they are leaving their home. However, as they journey on, they will encounter various difficulties. For example, when they are short on food and supplies, they have to work together to find resources. This kind of shared experience would make them more empathetic towards each other. Sasuke, who has always been reserved, might open up more about his family and his quest for revenge in a more sincere way to Naruto. Naruto, in turn, would share his insecurities about being the Jinchuriki. Over time, their relationship would evolve from comrades to true friends who are willing to sacrifice for each other.
One possible fanfic could be 'Abandoned Bonds'. In this story, Naruto's departure from Konoha sets off a chain of events where Sasuke is seen in a negative light as he fails to understand Naruto's reasons for leaving. However, it's important to note that Sasuke - bashing can be a divisive concept among fans as Sasuke has his own complex backstory and motives.
Naruto would probably be angry at first. He's always been a free - spirited person, and being kidnapped by Sasuke, his friend - turned - rival, would surely make him mad. He'd likely try to fight back immediately, using his ninja skills and his never - give - up attitude.
Naruto could also use his new jutsu or skills he has acquired. He might show Sasuke that he has become stronger and that they could face whatever Sasuke is running from together. He could block Sasuke's path physically and then start talking some sense into him, like how leaving won't solve his problems but will only create more.
Sasuke could be intrigued. If he comes across a well - written fanfic that really captures the essence of his relationship with Naruto or offers a new perspective on his goals and journey, he might get drawn into it. He might start to think about how these different ideas could fit into his own understanding of his life and the world around him. For instance, if a fanfic shows him a different path he could have taken, it might make him reflect on his choices.
Naruto could use his superhuman stamina to keep watch all night. His positive energy would also boost the morale of the Hogwarts students. Sasuke, on the other hand, would use his combat skills. He could set up traps around the perimeter of Hogwarts using his ninja knowledge.
Kakashi would be deeply affected. He has mentored both Sasuke and Sakura. This would make him question his own teachings and his ability to protect his students. He might also feel a sense of responsibility and could become more involved in trying to bring Sasuke to justice or at least understand what drove him to such an extreme act.
Naruto would likely become more stable. With Anko as his adoptive mother, he'd have a stronger support system. He might be less impulsive as he has someone to guide him. Sasuke, on the other hand, could start to open up more. His cold exterior might soften as he experiences Anko's love and care. He could also learn to trust others more easily.
At first, it would be really awkward. Naruto might be all over the place, trying to make the best of the situation, while Sasuke would be cold and distant. But as time passes, they would start to communicate more. Naruto's positive attitude might slowly break down Sasuke's walls. They could start training together again, like old times, but with a new layer of closeness. Eventually, they might develop a deep respect and love for each other that goes beyond friendship.
Naruto would be devastated. Sasuke is his closest friend and rival. He would likely go into a state of deep mourning at first. He might isolate himself for a while, just trying to come to terms with the loss.
