He might encounter a hermit who lives in a tree and has some really strange habits. The hermit could offer Naruto some 'wise' advice that is actually just really absurd, like telling him to walk on his hands to find his true path.
Naruto might meet another lost ninja. This ninja could be from a destroyed village. They would understand each other's pain and loneliness. Together, they decide to start a family, building a new life far away from the memories of their past tragedies.
His journey could lead him to the outskirts of the ninja world, to places that are unknown and full of mystery. With the Rinnegan, he might be able to access hidden paths or dimensions. He could be exploring these uncharted areas to gain more power and understanding, away from the politics and rules of Konoha.
He might meet a young and idealistic ninja in Kumo. This ninja could show Naruto a different way of looking at the ninja world. Maybe this Kumo ninja has a more peaceful approach to resolving conflicts, which makes Naruto re - evaluate his own views on fighting and rivalry between villages.
He might meet Gaara. Since Gaara is the Kazekage of Suna, it's very likely that they would cross paths. Naruto and Gaara have a history, so their encounter could be filled with reminiscing about their past battles and how far they've come.
One reason could be that he feels ostracized. Despite his efforts to protect Konoha, some villagers still look at him with suspicion because of the Nine - Tails inside him. He might just get tired of constantly having to prove himself and decide to leave in search of a place where he can be accepted for who he is.
In a crossover scenario, Naruto could find allies in characters from other anime. For instance, if he enters the world of One Piece, Luffy and his crew could be his allies. They share the common trait of having big dreams and a strong sense of loyalty. Luffy would be drawn to Naruto's determination, and together they could face any challenges in this new world.
One possibility could be that Naruto leaves Konoha and stumbles upon a village where everyone talks in rhymes. He tries to communicate but ends up making a comical mess of things. For example, when he asks for food, he says it all wrong and the villagers think he's performing a new kind of comedy act.
He could meet other powerful ninjas from different villages. Maybe some reclusive ninjas who are experts in certain jutsu that can help Naruto enhance his skills. For instance, he might come across a ninja who is a master of water jutsu in a far - flung land near a large body of water.
Well, it's a very interesting concept. Naruto leaving Konoha and his family could be due to some dark secrets he uncovers about the village or his family. As he leaves, he could be on a quest to find the truth. Along the way, he'll face many challenges, both physically and emotionally. He'll have to deal with loneliness, but also with the newfound freedom. He might cross paths with old enemies who now see him as a rogue ninja and try to take advantage of his situation, or he could meet new friends who help him through his tough times.
He might meet other wandering ninjas who are also on a quest for power or knowledge. They could either become his allies or foes depending on their motives.
