One interesting moment could be when Kakashi trains Naruto in a unique way that wasn't shown in the original series. For example, he might take Naruto to a special training ground in the fanfiction and teach him a new jutsu by using his own experiences in a more in - depth way than in the canon.
Well, there could be. Fanfiction writers love to explore unique and unexpected relationships. Since Naruto and Kakashi are both popular characters in the Naruto universe, some writers might come up with such a plot for the sake of creativity and exploring different storylines. But it's not a part of the official Naruto story.
In this fanfiction, Kakashi could also be Naruto's mentor in magecraft. Kakashi is known for his adaptability. He could start to study mage powers along with Naruto. They could learn together about new forms of magic, and Kakashi could use his combat experience to help Naruto understand how to use his mage powers in battle situations.
A traveling nen master could be Naruto's mentor. This master could be on a journey to spread the knowledge of nen. He crosses paths with Naruto and decides to teach him. The master might have a strict teaching style, pushing Naruto to his limits, but also guiding him carefully through the complex world of nen.
There's a possibility that it's a spirit or a deity in the world of bending. This entity is impressed by Naruto's tenacity and chooses to guide him on his journey of learning bending.
Sasuke could be a popular character. He might be involved in the story in a way that either helps or hinders the situation where Naruto hurts Kakashi. For example, if Sasuke tries to stop Naruto from doing something stupid that would hurt Kakashi.
Another reason could be related to Kakashi's past actions. If there are some secrets or things Kakashi did in the past that come to light and Naruto doesn't like them, he could snap at Kakashi. Naruto has a strong sense of justice and loyalty, so if he feels betrayed or misled by Kakashi, his reaction could be to snap.
It could be Kakashi. Since Kakashi has a wealth of knowledge and experience, he might take Naruto on a secret training journey. He could teach Naruto some advanced sharingan - related techniques that Naruto can adapt to his own fighting style, even though he doesn't have the sharingan himself.
However, Naruto also has a lot to offer. So, in a way, they could be mutual mentors. Naruto's unwavering determination and his experience in facing powerful foes could inspire Shikamaru to be more bold in his actions. So, it's not necessarily a one - way mentorship.
Kakashi might be initially surprised. But then, he would probably use it as a teaching moment for Naruto. He could say something like 'Naruto, stealing is not the way of a ninja.' And then give him a punishment like extra training.
