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 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.
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.
One possible plot development could be that Naruto quickly masters basic chakra control under Jiraiya's strict training. This early success might make Naruto overconfident, leading to a challenge where he realizes he still has a lot to learn. For example, he might face a powerful opponent in a sparring match arranged by Jiraiya and struggle initially, teaching him the importance of continuous training.
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.
Well, one interesting aspect could be the unique training scenarios it might depict for Naruto. It could show him training in ways that weren't explored in the original series, like training with long - lost techniques or under the guidance of unexpected mentors.
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.
Sasuke could be involved. Since they have a complex relationship, Sasuke might either be a rival during Naruto's training, pushing him to be better, or he could end up joining Naruto in some training sessions to become stronger together.
Naruto's character development is significant. With Jiraiya's serious training, Naruto becomes more disciplined. He learns advanced jutsu quicker and starts to understand the deeper aspects of being a ninja. His confidence grows not just in his strength but also in his decision - making abilities.
