One challenge could be Naruto's own independence. He's been on his own journey for so long that he might be reluctant to give up his newfound freedom. Another challenge could be trust issues. If the family has let him down in the past, it'll be hard for Naruto to believe that they've really changed.
In the 'naruto wants to be promoted' fanfic, Naruto may struggle with the traditional ways of the village. His unique approach to being a ninja, which often involves thinking outside the box, might not be fully understood or accepted by the old - school ninja leaders. This lack of understanding could lead to resistance against his promotion. Additionally, he may have to deal with false accusations. Some might spread rumors about him to prevent his rise in rank, and he'll have to prove his innocence and worthiness for promotion.
They could start by showing him genuine love and acceptance. For example, his father could share all the things he sacrificed for Naruto in the past. His mother could cook his favorite meals, just like she used to dream about when he was a baby. And his friends in the family could show him how much they missed him and how empty the family feels without him.
His mother, Kushina, could also be part of the family that wants him back. She was a kind - hearted and strong - willed woman. If she were alive in the fanfiction, she would be desperate to have her son with her. She would want to protect Naruto and share all the things she didn't get to when he was growing up, like teaching him about their Uzumaki heritage.
One challenge Naruto might face is Sasuke's own will. Sasuke may be so consumed by his thirst for revenge or his dark path that he doesn't want to be brought back. Naruto has to break through that mental barrier. Another challenge could be the external forces that are influencing Sasuke, like the people or organizations that have turned him to the dark side. Naruto has to deal with them as well.
There are numerous possibilities in this 'naruto's family wants him back fanfiction'. Naruto's family could consist of powerful shinobi who were exiled or had to go into hiding for some reason. Now that they are back and want Naruto, they might offer him new powers or knowledge. This could change Naruto's role in the village of Konoha. He might become a bridge between his family and the village, leading to new alliances and adventures. Or perhaps his family has some secrets about his heritage that could change how he views himself and his place in the ninja world.
One challenge could be dealing with the new dynamic between him and the fem Kyuubi. If she is overly possessive, Naruto might feel pressured and it could affect his relationships with other friends. For instance, if he has to constantly consider the fem Kyuubi's feelings, he may not be able to hang out with his friends as freely.
Definitely Naruto himself. He is the one Konoha wants back, after all. And then there would be his old friends like Sasuke. Sasuke might play an interesting role, either helping Konoha get Naruto back or being a bit hesitant because of his own complex relationship with Naruto. Also, characters like Iruka - sensei, who has always been like a father figure to Naruto, would be important. He could be the one who first realizes how much Konoha needs Naruto and starts the ball rolling to get him back.
Well, she might face the challenge of Naruto's trust. Since she has been absent for so long, Naruto may not trust her immediately. Also, the ninja world is full of threats. There could be enemies who try to stop her from getting close to Naruto. And Naruto has his own sense of identity which is deeply rooted in being an orphan and a self - made ninja. Kushina has to respect that and find a way to fit into his life without disrupting it completely.
One challenge could be the differences in their village cultures. Konoha and Suna have different traditions, and they might have to find a way to blend them for their family. For example, in terms of how their children are trained as shinobi.
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.
