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.
It could be that the overall direction of the Naruto franchise changed in a way that made the existing Jiraiya fanfiction no longer relevant or interesting to write. For example, new official content might have contradicted the ideas in the fanfiction. Additionally, the writer may have had a change of heart about Jiraiya as a character to focus on. Maybe they discovered other aspects of the Naruto universe that they found more appealing and decided to shift their creative efforts elsewhere.
Well, perhaps the fanfiction writer faced some negative feedback regarding their portrayal of Jiraiya in the fanfiction. If they felt that they couldn't meet the expectations of the readers or were constantly criticized, they might have decided to abandon it. Also, real - life commitments like work, school or personal issues could have come in the way, making it impossible for them to continue writing about Jiraiya in Naruto fanfiction.
In some fanfictions, external forces might be the cause. Perhaps a powerful enemy threatens Hinata and tells her that staying with Naruto will put him in danger. So, to protect Naruto, she decides to abandon him. This adds a tragic and self - sacrificing element to the story.
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.
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.
Some writers might want to create a unique or controversial take. They think by bashing a well - liked character like Jiraiya, they can attract more attention to their fanfiction.
One possible reason could be that Naruto might feel Jiraiya is being too overbearing in his training methods. In some fanfictions, Jiraiya might push Naruto too hard without considering his emotional state, leading to Naruto snapping.
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.
One possible reason could be jealousy. If Naruto becomes too powerful too quickly, his friends might feel overshadowed and abandon him out of envy.
Another reason could be that Jiraiya has some doubts about Naruto's readiness or potential. He might think that Naruto is not yet at the level where he can fully benefit from Jiraiya's training. For example, Naruto may lack some basic skills or knowledge that Jiraiya believes are necessary prerequisites for his more advanced training.
One possible reason could be some sort of dark influence or curse that makes her lose her maternal instincts. Maybe a powerful enemy targets her and in order to protect Naruto from further danger related to her, she feels forced to abandon him. Another reason might be that she is made to believe false information about Naruto, such as that he will bring great disaster to the village in the future.
