It could be due to the current situation in the village. There might be threats that required Naruto to stay. Tsunade, as the Hokage, had to consider the overall safety and stability of the village. So, she denied Naruto's request for the training trip to ensure he was available in case of any emergency.
In many Naruto fanfictions about Kakashi training Naruto, Kakashi might push Naruto to new limits. He could focus on Naruto's Rasengan training, making it more powerful or teaching him new variations. For example, Kakashi might introduce elements to the Rasengan, like wind or lightning, to enhance its destructive power. This kind of training would not only strengthen Naruto physically but also help him understand chakra better.
He might become more determined to prove himself to Tsunade. This could make him train even harder within the village. He could also start to question Tsunade's decisions and try to find ways to convince her that he is ready for such a training trip in the future.
Yes, there might be some fanfictions like that. In some fan - created stories, Kakashi could use hypnosis as an unorthodox training method for Naruto. It could be a way to help Naruto access deeper levels of chakra control or overcome mental blocks.
In the fanfiction, Kakashi might train Naruto in teamwork. Even though Naruto is often a solo fighter, Kakashi could show him the importance of working with others. He could arrange mock battles where Naruto has to team up with other characters, like Sakura or Shikamaru, and learn how to coordinate their attacks and defenses.
One possible result is that Naruto becomes much stronger in a shorter period compared to the original story. His combat skills improve significantly, allowing him to take on more difficult missions. For example, he might be able to defeat enemies that were previously out of his league with ease.
In this alternate scenario, it could lead to a lot of tension and conflict within the team. Naruto might be less inclined to follow Kakashi's lead and could even try to train on his own, causing problems for the group's dynamics.
Naruto's training would be more personalized. Instead of the general training he received in the academy, Kakashi would tailor his training to Naruto's strengths and weaknesses. Given Kakashi's knowledge of different ninja arts, he could expose Naruto to elements of different clans' techniques. This would make Naruto a more versatile ninja. Kakashi would also likely push Naruto to think more analytically during combat, rather than relying solely on brute force. This would help Naruto become a more well - rounded and formidable ninja in the long run.
Naruto could be confused. He may not understand why he was denied when he has accomplished so much. He might start to question the system and those in power. This could lead him to have some internal conflict as he tries to figure out whether he should continue to strive for the promotion within the existing framework or find his own path.
