Jiraiya may use a form of mental training. He could put Naruto in situations where he has to face his deepest fears. This not only strengthens Naruto's willpower but also helps him gain better control over his emotions. For example, Naruto might have to face illusions of losing his friends. By overcoming these, he becomes more mentally resilient.
One unique method could be training in extreme environments. Jiraiya might take Naruto to a desolate desert or a freezing tundra to test his endurance and ability to adapt. This forces Naruto to find new ways to use his chakra and skills.
Jiraiya's training methods in the fanfiction are quite diverse. He may start with basic physical conditioning such as push - ups, sit - ups and long - distance running to build Naruto's stamina. Then, he moves on to chakra - based training. He has Naruto practice chakra control by doing things like walking on water or climbing vertical surfaces using chakra. Jiraiya also teaches Naruto about the different types of chakra natures and how to combine them for more powerful jutsus. Additionally, he arranges mock battles for Naruto against various opponents, which could be either real people or summoned creatures, to improve Naruto's battle strategy and reaction time.
Jiraiya's training in the fanfiction might focus on Naruto's inner strength as well. He could help Naruto better understand and control the Nine - Tails' power. This new - found control would give Naruto a sense of calm and authority. His character would shift from being just a loud - mouthed underdog to a more respected and powerful ninja. Naruto would also learn about loyalty and sacrifice from Jiraiya, which would shape his values.
The training makes Naruto more confident in his abilities. Jiraiya constantly challenges Naruto and as Naruto overcomes these challenges, he realizes his own strength. He starts to believe in himself more, which is evident in the way he faces stronger opponents without hesitation later on. Also, Jiraiya's teachings about the ninja way and the importance of protecting those you love make Naruto more determined and focused on his goals.
In the fanfiction, Jiraiya's training methods for Naruto are comprehensive. Firstly, there's the physical aspect. Jiraiya could be making Naruto do things like carrying heavy rocks for long distances to build up his endurance. For ninjutsu, he'd be teaching Naruto not just new techniques but also how to innovate and combine existing ones. He might also take Naruto on dangerous missions where Naruto has to learn on the fly. Jiraiya would also focus on Naruto's mental strength, teaching him how to stay calm under pressure and not let emotions cloud his judgment during battles.
One possible reason could be that in this fanfiction, Jiraiya might be preoccupied with other important matters. Maybe he has a secret mission that demands his full attention and he simply doesn't have the time to train Naruto. Another reason could be that there is some sort of conflict or misunderstanding between them that prevents Jiraiya from taking Naruto under his wing. For example, Naruto might have unknowingly offended Jiraiya in some way, or there could be a prophecy or external force that is keeping them apart for the time being.
One idea could be that Jiraiya focuses on Naruto's rasengan training in a more extreme way. He takes Naruto to a secluded place full of natural challenges like strong water currents or rocky terrains. There, Naruto has to constantly adapt and use his rasengan in different situations to overcome obstacles. Another plot could involve Jiraiya teaching Naruto some secret clan jutsus that he discovered during his travels, which could give Naruto an edge in future battles. And also, Jiraiya could train Naruto in stealth and espionage skills, which are essential for a shinobi but Naruto hasn't had much focus on before.
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 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.
In the fanfiction, there might be a moment where Jiraiya takes Naruto to a secret training ground. This place has some special chakra - enhancing properties. Naruto has to endure a series of tough physical and mental challenges there. He struggles at first but gradually overcomes them, growing stronger in the process.
Well, if Jiraiya had trained Naruto from the start, Naruto might have developed a more strategic mindset and better control over his chakra. Also, he could have learned some secret techniques that Jiraiya knew but never got the chance to teach him.
