In the fanfic, perhaps Naruto meets Jiraiya in the afterlife. Jiraiya gives Naruto some final words of wisdom and power that Naruto then uses to save the Hidden Leaf from a great danger back in the living world. This would be a very emotional and spiritual encounter.
One possible plot could be that Naruto goes on a special training journey with Jiraiya again, but this time they encounter a new and powerful enemy that has a connection to Jiraiya's past. Naruto has to learn a new jutsu from Jiraiya to defeat this foe.
In this fanfiction, perhaps Jiraiya didn't actually die. He was in a hidden place recovering from a serious injury. When he meets Naruto again, Naruto is shocked but overjoyed. Jiraiya then shares his newfound knowledge and powers with Naruto, and they team up to take on a powerful organization that threatens the Hidden Leaf Village. Jiraiya could teach Naruto some advanced Sage Mode techniques that he had been working on during his absence.
The plot might involve Naruto and Jiraiya getting transported to a different dimension. In this strange new world, they have to work together to find a way back home. They meet all kinds of strange creatures and characters. Jiraiya uses his wisdom and experience to navigate through this new environment, while Naruto's determination and growing power help them face the challenges. And during this adventure, Naruto might also develop a new form of his Rasengan, inspired by the things they encounter in this dimension.
Well, it could be about Naruto getting some really early and special training from Jiraiya. Maybe Jiraiya sees Naruto's potential right away and starts teaching him some basic but important ninja skills like how to better control his chakra. It might also involve some fun adventures where they encounter some small - time villains in the Land of Fire.
Perhaps in this fanfic, Naruto would be more confident earlier in his life. Since Jiraiya is a strong and experienced ninja, his early presence in Naruto's life could provide a sense of security. They might go on missions together earlier, and Naruto could learn about the importance of teamwork and strategy from Jiraiya at a young age. This could potentially change the course of Naruto's development, making him a more well - rounded and powerful ninja much faster.
One possible plot could be that Naruto has been misinformed about Jiraiya's actions. Maybe he heard false rumors that Jiraiya was involved in something bad. So, he decides to ignore Jiraiya out of disappointment. As a result, Jiraiya has to find ways to prove his innocence and regain Naruto's trust.
Maybe in the fanfiction, Jiraiya is summoned by a new jutsu gone wrong. When he meets Boruto, he mistakes him for Naruto at first. As they interact, Jiraiya realizes Boruto's own unique struggles. He shares his wisdom about handling the expectations that come with being a ninja from a famous family, and Boruto learns a great deal from him.
One possibility could be that Jiraiya is under the influence of a powerful enemy's jutsu that makes him lose control of his actions and accidentally attacks Naruto. This could lead to a great deal of guilt and self - loathing for Jiraiya later.
One possible plot could be Naruto making great leaps in his ninja skills. He might learn powerful jutsu more quickly under Jiraiya's intense training regime. For example, he could master new forms of Rasengan faster and also gain better control over his chakra.
Perhaps the mushroom is a rare and magical item that is said to grant great power. Jiraiya has been searching for it for years to use it against a powerful enemy. Naruko accidentally discovers its location. At first, Jiraiya is hesitant to involve Naruko, but she convinces him that she can be of help. As they try to retrieve the mushroom, they face many challenges, including traps set by other ninja who also want the mushroom for their own purposes.
One possible plot could be that Jiraiya, after all his travels, returns to the Hidden Leaf Village and meets Naruto. They could have a series of adventures together, like exploring some long - forgotten parts of the village or training the new generation of shinobi. Jiraiya could share some new jutsu or ninja wisdom with Naruto, which Naruto can then pass on to his students.
