He would likely develop a great sense of empathy. Growing up in a brothel, he'd see people at their most vulnerable. This would make him more understanding of others' pain and struggles in the ninja world. He might be more likely to offer help and support to those in need.
Naruto could become more street - smart. In a brothel environment, he'd have to deal with all kinds of characters. This would give him the ability to quickly assess situations and people. Also, he'd probably develop a strong sense of loyalty to those he considers family in the brothel, which would translate into his relationships in the ninja world as well. For example, he'd be the kind of person who'd go to great lengths to protect his friends. And his unique upbringing would make him stand out from other ninjas, with his own set of values that are influenced by the diverse community in the brothel.
Naruto's character would develop a different sense of loyalty. Instead of being loyal to Konoha, he'd be loyal to Kumo. His goals would change too. Maybe instead of aiming to be Hokage, he'd aim to be one of the top - ranking ninjas in Kumo. His social skills could also be different. Kumo has a different social environment, so he might be more rough around the edges in his interactions.
Naruto's character would likely be more edgy. With Obito's influence, he might be quicker to question the village's motives. He'd also be more powerful in different ways, like having a better understanding of space - time ninjutsu early on.
Naruto's character development in this fanfic would be quite remarkable. Iroh's teachings would shape Naruto into a more centered individual. He would no longer rely solely on his brute strength and the Nine - Tails' power. Instead, he would start to value wisdom and diplomacy. Iroh could teach Naruto how to handle his emotions better, especially his anger and frustration. As a result, Naruto would be a more balanced ninja, able to face challenges with a cool head and make more rational decisions. His relationships with others would also change, as he would approach them with more empathy and understanding, having learned from Iroh's kind and patient nature.
In this kind of fanfic, Naruto's character might develop in a way that he is more attuned to the spiritual side of the ninja world. Since Karma has some sort of otherworldly origin, he could start to see things from a different perspective. He might be more empathetic towards enemies who also have strange powers, as he understands the burden of having something that others don't understand. His growth would be about not only physical and ninja skills but also about his understanding of different forces at play in the world.
Naruto's character could develop a sense of duty towards the Hidden Cloud Village. He would be influenced by the Raikage's leadership, so he might be more disciplined and less of a prankster. Also, he could be more attuned to the politics and power dynamics within the Cloud Village, which would shape his interactions with other ninja villages.
His social skills might be underdeveloped at first. Since he was raised by wolves, he may not understand human social cues and norms easily. He could be more solitary and have trouble making friends in the beginning.
In this non - adult version, Naruto's presence in the brothel could be a source of change. He might introduce new ideas to the people there, like the importance of self - respect and dreams outside of the brothel life. The story could show how he tries to break the cycle of what a brothel represents in that fictional world, and how he uses his experiences there to become a more well - rounded and compassionate ninja.
His character would grow in a more self - reliant way. He would be forced to face his insecurities alone. This could make him more introverted at first, but as he discovers his own strength, he would become a more confident and self - assured Naruto. His sense of justice may also become more complex, as he questions the values of the village that allowed his family to abandon him.
His character may develop a sense of independence. Since he's raised in the wild, he has to rely on himself. He'll be more self - sufficient and less likely to trust others easily at first.
His character might be more hardened. Growing up with Yahiko, he'd be exposed to the harsher side of the ninja world earlier. So he'd be less likely to trust blindly.
