To develop this theme, the writer could also focus on Kakashi's relationships. His guilt might cause him to distance himself from others, like his students. A good fanfiction would show how Naruto tries to break through that wall of guilt and help Kakashi move forward. This can add a lot of emotional depth to the story.
There is a fanfiction where Kakashi feels guilty for not being able to protect his comrades better. In this story, his guilt drives him to train Naruto more rigorously, but also makes him question his own worth as a mentor. It delves deep into his psyche and how he copes with his feelings.
The person who made Kakashi feel guilty for the rest of his life was Reina Hatake. I recommend a novel related to the Hatake clan,"The Last Man of the Hatake Clan of the Wood Leaf." Please read it. I hope you like this fairy's recommendation. Muah ~๐
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.
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.
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.
One more common theme is the team - up or rivalry between characters from both universes. You'll often see Naruto and his friends forming alliances with Guilty Gear characters to take on powerful foes. Or there could be rivalries where Naruto has to prove himself against a powerful Guilty Gear character. These themes help to create exciting and engaging stories that combine the best elements of both Naruto and Guilty Gear.
A really creative one is 'Guilty Crown Elements in Naruto's World'. It imagines what would happen if the technology and power concepts from Guilty Crown were introduced into the Naruto universe. It has some amazing battle scenes where Naruto and his friends face new threats with a blend of both worlds' powers.
One possible reason could be that Kakashi is preoccupied with other important matters in the village. Maybe he has some top - secret missions or tasks assigned by the Hokage that demand his full attention, leaving him with little time to focus on Naruto.
