In fanfiction, Jiraiya seeing Naruto as Hokage can be a very emotional moment. It could be a vision Jiraiya has in a story where he's still alive, or perhaps it's a memory in a story set after his death. This often shows Jiraiya's pride in Naruto and his belief in Naruto's potential to lead the village.
One common theme is the passing of the torch. Jiraiya, who was part of the older generation, sees Naruto taking on the leadership role, representing the new era. Another theme is the realization of dreams. Jiraiya always hoped for Naruto's success, and seeing him as Hokage is that dream coming true.
One popular 'Naruto became Hokage' fanfiction is 'The Hokage's Legacy'. In this story, Naruto not only becomes Hokage but also has to face new and unexpected threats to the village. Another great one is 'Naruto: Hokage's Ascension' which focuses on Naruto's journey in the early days of his Hokage -ship, dealing with political intrigue within the village.
Well, Naruto would probably learn a great deal more about the world of ninjas at a faster pace. Jiraiya was a very experienced and powerful ninja. He could teach Naruto some really advanced jutsu, like the Rasengan much quicker. Also, Naruto might grow up to be more like Jiraiya in terms of his attitude towards women, which could lead to some interesting adventures and misadventures.
Perhaps a perk is the ability to shape the future of the ninja world. As Hokage, one can inspire the younger generation of ninjas. They can create new ninja academies or training programs. They also have the power to pardon or punish ninjas according to their deeds, which helps in maintaining law and order in the village.
Jiraiya is frequently shown as a very dedicated mentor. He is willing to sacrifice his own time and resources to train and guide his students. In some fanfictions, he goes to great lengths to protect his students from harm, even putting his own life on the line. This selfless aspect of his character is often emphasized.
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.
Their relationship would deepen. Itachi becoming Hokage would mean that Naruto has someone he truly admires in the highest position. Naruto would be more eager to prove himself worthy in Itachi's eyes. Itachi, on the other hand, would see Naruto as a symbol of hope and the future of the village. They would likely have private conversations about the future of Konoha, with Itachi sharing his long - term plans and Naruto providing his unique perspective based on his own experiences. This would create a bond that is not just based on respect but also on a shared vision for the village.
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.
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.
