On the other hand, Sasuke could also be angry. He might see Naruto's departure as a sign of weakness or as a betrayal of their shared past. However, as the story progresses, he may come to understand Naruto's reasons and start to support his decision, especially if he realizes that Naruto is doing it for the greater good of the village and their relationship.
He could feel a sense of guilt. Sasuke might think that his actions or their relationship issues pushed Naruto to leave. He may then set out to find Naruto, not only to bring him back but also to resolve their long - standing issues. For example, if there were unspoken words or unresolved fights between them, Sasuke would see this as an opportunity to set things right.
In the sasunaru context, perhaps a rift between Sasuke and Naruto makes Naruto feel like he needs to leave to sort out his feelings. He might think that staying in the village constantly reminded of Sasuke and their complicated relationship is too much to bear, so he leaves to find his own path and hopefully reconcile with Sasuke on his own terms.
The ninja elders in Konoha could see it as a potential threat. They might worry that Fem Naruto leaving could expose Konoha's secrets or that she could be turned against the village by enemies. So, they would start to take measures to protect Konoha's interests. They could send out spies to keep an eye on her or try to find a way to bring her back. On the other hand, the younger generation of ninjas might be inspired by her courage to break free and seek their own paths outside of the village.
Naruto might initially be in denial. He's so used to having Sakura around and believing that they have a future together. So when she leaves for Sasuke, he might think it's just a temporary thing or that she's been influenced by something or someone. But as time passes and he realizes it's real, he would be deeply hurt. He might also start to question his own self - worth, thinking that he wasn't good enough for Sakura. And he might even try to win her back at first, but then slowly come to accept the situation and focus on his other responsibilities like being a ninja and protecting the village.
Well, initially, there would be chaos in the village. People would start to spread rumors about why Naruto left. His closest friends like Sakura and Kakashi would be devastated. They would try to figure out where he went and why. The Hokage at the time would have to make a decision. They could either try to convince Naruto to come back through peaceful means or prepare for the worst - case scenario if Naruto turned against the village. The village as a whole would have to face the fact that one of their most prominent members left, and it would have an impact on their reputation among other villages as well.
Naruto might encounter a group of rogue ninjas. At first, they seem like enemies, but as he gets to know them, he realizes they have their own reasons for being outcasts. They could teach Naruto some unorthodox fighting styles that are not taught in the Leaf Village. Also, there could be a mysterious traveler who has knowledge about Naruto's family that even he doesn't know. This traveler could be the key to unlocking some hidden power within Naruto.
Some might be in shock. Naruto, regardless of being male or female in this fanfiction, has been a significant part of the village. People who have come to know her would be surprised that she would leave. They might start to question if there was something they could have done to prevent it.
They could face challenges from the ninja world's authorities who might see them as deserters. Other villages might try to capture them to gain an advantage over Konoha.
Well, Naruto could leave the village in a fanfic due to a prophecy. He might believe that leaving is the only way to fulfill a greater destiny that the village can't support. As he leaves, he starts to explore different cultures of the ninja world. He learns about new forms of jutsu and how other villages operate. He could also form a team with outcasts from different villages, and together they strive to change the way the ninja world views things.
One possibility is that Naruto is on a quest for self - discovery. Leaving the village to find the Sage gives him a chance to be away from the familiar and face new challenges alone. He might encounter different types of enemies and allies during this journey. This could also be a way for him to prove himself not just to the village but also to himself. He wants to show that he can grow and become stronger without always relying on the village's resources.
Definitely Naruto and Sasuke. Naruto is the one leaving the village, so he's a central figure. Sasuke, given the 'narusasu' aspect, is bound to play a crucial role too. He could be the one Naruto is leaving behind, or he could be the one who follows Naruto out of the village. There might also be other supporting characters from the Naruto universe like Kakashi or Sakura who could be affected by Naruto's departure.
