Fanfiction: Naruto Revives Jiraiya - Is it Possible in the Naruto Universe?

It could be that Naruto finds a way to reverse time in a small area. This would require an extremely powerful and dangerous technique. He might have to sacrifice something in return, like some of his own memories or a part of his chakra permanently. But if he manages to do it, he could go back to the time when Mito Uzumaki was still alive and bring her forward to the present.

In some fanfictions, Naruto might use the power of the tailed beasts. Since he has a bond with all of them, they could combine their chakra in a way that creates a life - restoring energy. This energy could then be used to revive Jiraiya. Or perhaps Naruto, after achieving a new level of sage mode, discovers that he can access a spiritual realm where the dead reside. He battles the forces there and brings Jiraiya back. Also, there could be a situation where the memories and wills of all those Jiraiya has influenced come together and manifest as a power that Naruto uses to revive him.

One possible reason could be that Naruto feels he has learned all he can from Jiraiya at that point. Maybe he has reached a level in his training where he believes he needs new experiences and challenges that Jiraiya can no longer provide.

Perhaps in this fanfiction, Jiraiya discovers that Naruto is going to be the cause of a major catastrophe in the future. He might have seen a prophecy or some sort of sign that convinces him Naruto has to die to prevent this. It could also be that Jiraiya has been misled by false information about Naruto, which makes him think that Naruto has become an evil force that needs to be eliminated.

It's highly unlikely. In the Naruto universe, there's no concept of fanfiction as we know it. There are no computers or the Internet where fanfictions are typically hosted. Naruto is too busy with his ninja duties, training, and saving the world to even think about something like fanfiction.

One possible reason could be that Naruto feels he has learned all he can from Jiraiya at that point. Maybe he wants to explore his own path independently and test his skills without Jiraiya's constant guidance.

Perhaps Jiraiya has some personal issues or inner conflicts. He might be dealing with his own past traumas or demons that prevent him from taking on the role of Naruto's trainer. For example, he could be haunted by the failures in his previous relationships or battles, and he feels unfit to train Naruto until he sorts out his own problems.

It's highly unlikely. In the Naruto universe, they don't really have the concept of fanfiction as we do in our world. Their focus is more on real - life ninja activities, training, and village affairs.

One possible reason could be that the writer lost inspiration. Jiraiya has a complex character in the Naruto series, and it might be difficult to keep coming up with new and interesting plotlines for him in fanfiction. Another reason could be that the writer got involved in other projects or fandoms and simply didn't have the time to continue with the Naruto fanfiction centered around Jiraiya.

One possible reason could be jealousy. Maybe in the fanfiction, Jiraiya gives more attention to another character, and Naruto, being young and impulsive, starts to hate him for it.
