The fanfic might also explore the idea that Naruto is not okay in terms of his relationships. Maybe he has had a falling - out with his friends or there are some unresolved issues within the village. Jiraiya, being observant, realizes these problems. He might then take it upon himself to act as a mediator in Naruto's relationship issues or try to boost Naruto's confidence within the village so that he can feel more at ease and get back to his normal self.
The main characters are Jiraiya and Naruto. Jiraiya is the one who realizes that Naruto is not okay. His role is like that of a mentor or a guardian. He is more experienced and has to figure out what's wrong with Naruto. Naruto, on the other hand, is the one in distress. He is usually a strong and determined character, but in this fanfic, he is facing some sort of problem that is affecting his normal state.
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.
It can create a sense of growth for Naruto. Without Jiraiya by his side, he has to rely more on his own instincts and the skills he has already acquired. This can lead to new character development as he faces challenges alone.
Naruto would likely experience a great deal of emotional turmoil. He has always looked up to Jiraiya as a mentor and father figure. So, this betrayal could shatter his trust in people and make him more cynical. He might also become more withdrawn and less likely to open up to others in the future.
One great fanfic could be about their adventures before Naruto was born. It might explore their relationship dynamics, how they trained together and supported each other. Maybe in this fanfic, Jiraiya tries to convince Tsunade to take on more dangerous missions with him, showing his trust in her abilities.
It could lead to Naruto becoming even stronger and more skilled than in the original story. Jiraiya's training methods might unlock new powers for him.
Perhaps the fanfic is exploring an alternate universe concept. In this universe, the relationship between Jiraiya and Naruto has been strained due to different events that didn't occur in the original story. Jiraiya's actions that seem like a betrayal could be a result of different political or personal circumstances in this alternate world. For instance, if there was a power struggle in the Hidden Leaf Village and Jiraiya sided with a different faction for some reason, Naruto would feel betrayed.
Well, it depends on the specific fanfic. Some might portray Naruto as loving all of Jiraiya's books because they are a link to his beloved teacher. However, other fanfics could show Naruto having a more nuanced view, perhaps not loving every single book but still having a great deal of respect for them.
The reasons are multi - fold. Firstly, Jiraiya's books are a source of inspiration for Naruto. They are full of tales of courage and perseverance, which Naruto admires. Secondly, these books are a form of emotional connection. Naruto lost Jiraiya, and the books are like a piece of him that Naruto can hold on to. Moreover, the books might contain hidden messages or prophecies that Naruto is interested in, as they could potentially help him in his journey to protect the village and become a better ninja.
