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.
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.
There could be no official plot for such a fanfic as it violates the essence of the Naruto series. Naruto is a ninja who fights for justice and the well - being of his comrades and village. A brothel - running Naruto is a warped and unacceptable idea that doesn't belong in the Naruto universe.
One possible plot could be that Harry, having known the hardships of being an orphan himself, decides to open an orphanage at Hogwarts. He uses magic to create a warm and safe environment for the orphans. He teaches them magic, not just spells but also the values of friendship and courage, much like Dumbledore did for him.
The storyline could involve Harry using his experiences as an orphan to create a warm and magical place for the kids. He might teach them magic, share his tales of Hogwarts, and help them discover their own magical abilities. Maybe he'd also have some of his old friends like Hermione and Ron visit and help out with the kids' education.
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.
In a Naruto fanfic where Naruto runs away from Kushina, it could be due to various reasons. Maybe he feels misunderstood. For example, Kushina might be too strict with him in the fanfic's storyline, not allowing him to pursue his own ninja way freely, so he decides to run away to find his own path and prove himself.
There are very few if any appropriate fanfics with such a concept. The 'Naruto' series is mainly about ninja adventures, friendship, and growth. A concept like running a brothel goes against the positive and family - friendly themes of the original work. Most fan - created content focuses on the more canon - friendly aspects like battles, character relationships within the ninja world.
There would likely be a lot of negative reactions. Fans of the Naruto series who love the original themes of friendship, heroism, and ninja values would be appalled. The Naruto fandom is quite large and protective of the original spirit of the show, so this kind of fanfic would be seen as a desecration of the characters and the world that has been created.
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.
