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.
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.
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.
In the fanfic, Naruto could build the village by first establishing a set of rules and values that everyone can follow. Then, he'd probably use his connections. For example, he could ask his friends and allies from different villages to send resources or experts in construction. He might also use his own knowledge of the Leaf village's layout and infrastructure to create a similar but unique village. He'd ensure there are places for families to live, shops for trading, and of course, ninja training facilities. This way, the new village can thrive and be self - sufficient.
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.
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.
It could strengthen his relationships. If his heritage shows he has noble origins, people might respect him more and be more willing to be his friend or ally.
One possibility is that Naruto could bring a new sense of unity to Mist Village. His never - give - up attitude and ability to make friends might inspire the shinobi there. He could also learn unique Mist Village jutsu and combine them with his own skills, creating new and powerful fighting styles.
In some fanfics, Naruto might be made to hate the village because of how he was treated as a child. He was ostracized and shunned by many villagers due to the Nine - Tails sealed within him. This constant rejection could build up resentment over time in a fanfic - based scenario.
It could be that in this 'naruto of the demon village fanfic', Naruto discovers a hidden power within the demon village. This power could be related to an ancient demon that once lived there. He then has to figure out how to control or use this power for the greater good, while also dealing with the internal politics and power struggles within the demon village.
