If Naruto had left, it might have caused chaos in the village. His absence could have given rise to new villains or changed the relationships among the remaining characters. Also, his journey outside could have introduced him to unexpected allies and challenges.
It could lead to a whole new adventure and change the dynamics of the story. Maybe Naruto would face different challenges and form unexpected alliances.
In such a fanfiction, it could lead to a completely different power dynamic within the ninja village. Maybe Naruto's absence would give rise to new challenges and characters stepping up.
If Sasuke never left, the story would have taken a completely different turn. The dynamics between Naruto and Sasuke would have been much more straightforward, and their growth might have been along a different path.
It could be a village that focuses on both offensive and defensive capabilities. Naruto's ability to gather allies and Sasuke's strategic mind would make the village well - protected. There would probably be a council where they both have equal say. The architecture of the village might be a blend of Naruto's love for the traditional Leaf Village style and Sasuke's more modern and practical ideas. Maybe there would be a huge statue of both of them in the center, symbolizing their joint leadership.
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.
In one possibility, Naruto might leave the village to seek greater power on his own. He could feel that the village's teachings and training methods are limited. So, he embarks on a journey across different lands, meeting new shinobi and learning unique jutsu that the village doesn't offer. This could lead to him coming back much stronger, but also with a different perspective on the village and its values.
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.
One major challenge would be survival. Outside the village, he no longer has the support system of the Hidden Leaf. He'd have to find food, shelter, and deal with potential attacks from other shinobi or bandits. For example, in the wild, he might struggle to find clean water and safe places to sleep.
One reason could be a sense of disillusionment with the village's leadership. Maybe they discover some dark secrets about the elders and decide they can't be part of it anymore. Another reason might be to protect the village in their own way. They could think that by leaving, they draw danger away from their home. Also, they might be seeking a greater power or knowledge that can only be found outside the village.
