Some villagers might start to miss them. Naruto has always been a source of inspiration for many in the village, and Kiba is also well - known. Their departure could make some realize how important they were. Others might feel betrayed, thinking that they are deserting the village in a time of need.
Maybe it's to protect the village. He could discover a threat that he can only face away from the Leaf Village, to keep the danger from directly reaching his home and loved ones. He leaves as a form of self - sacrifice.
They might encounter powerful enemies outside the village. For example, they could run into a group of rogue ninjas who are looking for trouble. Naruto with his never - give - up attitude and Kiba with his strong fighting skills by his side, would have to use all their training to defend themselves.
They could go to the Land of Waves. It has a peaceful coastline and they might be able to start a new life there, away from the hustle and bustle of their village. Maybe Naruto could help the local fishermen and Hinata could use her skills to help the local medical facilities.
Well, they could go on a journey to explore new lands. Maybe they'll discover a hidden village with unique ninja techniques. They might meet new friends or face new enemies along the way.
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 villagers would likely be shocked. Naruto is a hero to many in Konoha, and Tsunade is the Hokage. Their sudden departure would cause a great deal of confusion and concern. Some might think that Konoha is in danger if two such important figures have left.
Some in the village would be sad to see them go. Naruto is a hero to many, and Hinata is also well - liked. People like Iruka would miss Naruto a great deal. But others might understand their need for a new life away from the village and support their decision.
Well, it might be that Naruto leaves the village to search for a new power source. In the context of a yaoi fanfic, he could meet a mysterious male stranger on his journey. They start off as comrades but gradually develop deeper feelings for each other. Their relationship could be full of drama, with Naruto having to balance his feelings for this new person and his ties to his old village friends.
It could change the power dynamics in the Naruto universe. If Naruto leaves the village in a yaoi fanfic, his absence might create a power vacuum. Enemies could see it as an opportunity to attack Konoha. Also, his new relationship with another male character could lead to new alliances or rivalries between villages depending on how the other villages view their relationship.
