He could meet other rogue ninjas. These are ninjas who have left their villages for various reasons, and they might be on a similar journey as Naruto. They could either help him or try to take advantage of his situation.
Well, Naruto might sell ramen in his shop. After all, he loves ramen so much. He could have his friends like Sasuke and Sakura helping out sometimes. Maybe there would be special ninja - themed items for sale too.
In a 'naruto runs away fanfic', one possible plot could be that Naruto runs away after feeling misunderstood by the village. He might go on a journey to find a place where he can truly belong. Along the way, he could meet new allies or enemies. For example, he might encounter a group of outcasts who are also on the run from different villages. They could team up and form a sort of 'runaway family' where Naruto learns new skills and perspectives outside of the Hidden Leaf's teachings.
Well, one possibility is that Naruto uses his own experiences as an orphan to create a warm and supportive environment in the orphanage. He might teach the kids ninjutsu skills and also important life lessons about friendship and perseverance.
Well, Naruto has a big heart. He would manage his business in a way that benefits the community. He'd offer fair prices, maybe even provide free services to those in need. He'd also hire people who are passionate about the business, not just for profit, but to create a positive and inclusive environment. He'd learn about business management as he goes, making mistakes but always striving to improve.
Well, first of all, the genin teams would be regulars. They need to stock up on basic ninja equipment. Then, the older ninjas who are retired might visit to relive their younger days by buying things they used to use. And don't forget the wandering ninjas. If Naruto's shop becomes famous enough, they would stop by to buy rare items or get some rest and information at the same time.
In a 'neglected Naruto runs to Uzu' fanfic, perhaps Naruto, feeling unwanted in Konoha, decides to seek out Uzushiogakure (Uzu). He might hope to find a place where he is accepted. Along the way, he could face various challenges like natural obstacles and maybe run into some bandits. He might also start to discover hidden powers within himself during this journey as he is forced to rely on his own strength.
The orphans themselves would be main characters. Each one could have their own backstory and personality. Some might be shy, while others could be more outgoing. They would be the ones directly affected by Naruto's care and teachings.
At first, Itachi might be a bit distant, but as they run away and are forced to rely on each other, a deeper connection forms. Naruto's positive attitude would gradually break down Itachi's walls. They could start sharing their hopes and fears. Itachi might open up about his family and his regrets, and Naruto would listen and offer his own perspective. This sharing would strengthen their bond, and they would become like brothers, protecting and supporting each other.
