Naruto would face several challenges. Firstly, he has to adapt to the different leadership style required of the First Hokage. He's been a free - spirited ninja, but now he has to be more diplomatic and make decisions for the whole village. There could be issues with the other villages too. They might be suspicious of Konoha having Naruto as a revived Hashirama. He also has to deal with the internal politics of Konoha. The various ninja clans and factions may have different opinions on his leadership, and he has to find a way to keep everyone in line while still staying true to his own beliefs. Moreover, he needs to figure out how to use the knowledge and abilities of the First Hokage in a way that benefits Konoha without causing chaos.
Well, Naruto would face a ton of challenges. For starters, he'd have to deal with the fact that he's not just Naruto anymore, but also representing the First Hokage. People would expect him to have all of Hashirama's knowledge and skills, which he may not immediately possess. There could be power struggles within Konoha. Some might see his revival as an opportunity to gain more power themselves. In terms of international relations, other villages might fear that Konoha is trying to gain too much influence with Naruto as the revived First Hokage. And on a personal level, he has to reconcile his old self with this new, more authoritative role. His friends might find it hard to interact with him as they used to, and he has to find a way to keep those relationships strong while being in this new position.
One major challenge would be living up to the legacy of the original First Hokage. Everyone would have high expectations of him. Another challenge could be dealing with the political aspects of being in such a high - ranking position. He's used to being more of an out - of - the - box hero, not a traditional leader. Also, he might face resistance from some of the older clans in Konoha who have their own ideas about how the village should be run. And he would need to balance his new role with his relationships with his friends, who might see him differently now.
He might face internal conflict. Naruto has always been an open and honest person, so keeping such a big secret could go against his nature. This could lead to him struggling with his conscience. Also, he would need to balance his normal life with his secret Hokage duties without raising suspicion. For instance, he can't always disappear suddenly to attend to Hokage business without people getting curious.
One challenge could be dealing with the traditionalist shinobi who might not be on board with his more unorthodox methods. They may resist changes he wants to make to the village's training or governance.
Naruto would face quite a few challenges. For one, his growth might be stunted as the team overprotects him. He could also face ridicule from outside the team who might see him as a weakling now. Moreover, he has to deal with the internal team dynamics where Sasuke may not be fully accepting of his new role and Naruto would have to prove himself constantly.
He would face political challenges. Some traditionalists in the village might oppose his more progressive ideas. Also, there would be administrative tasks like handling budgets and paperwork, which Naruto has no experience with. Another challenge could be dealing with rogue ninja who might see him as a target to prove themselves.
One challenge could be mastering difficult jutsus. The Third Hokage might set high standards for Naruto to learn complex techniques, which would be a struggle for him.
One challenge could be controlling the transformations. If he can't master when and how to transform, it could put him in dangerous situations. For example, transforming at the wrong time during a battle could leave him vulnerable.
Financial problems could be an issue. If they are just starting out in the modern world, finding good jobs might be tough. Naruto, with his impulsive nature, might make some bad financial decisions at first. And Yugito, who is used to a different kind of economy in the Naruto world, would have to adjust to things like paying rent, bills, etc. Also, they might face discrimination from people who sense that they are different, even if they don't know about their ninja powers.
One challenge could be adapting to the team's dynamics. Team 8 has its own way of operating, and Naruto is used to his own style with his friends. For instance, they might be more methodical in their planning, while Naruto is more of a 'jump - in - and - figure - it - out' type. So, he'd have to learn to follow their lead sometimes.
One big challenge would be public relations. Sasuke has a dark past, and some villagers might not trust him completely. Also, he's not as naturally warm and approachable as Naruto. He'd have to work on that. Another challenge could be dealing with the paperwork. Sasuke is used to being out in the field, not sitting behind a desk. And he might face opposition from some of the more traditional ninja clans who don't like his new ideas for the village.
There could also be external threats. Maybe other villains or rival ninja clans see the apartment building as a target. They might try to take it over or destroy it to undermine Naruto's influence in the village. Naruto would then have to use his combat skills and strategic thinking to protect his property.
