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.
Jiraiya could also train Naruto seriously in fanfiction through intense physical conditioning. He might make Naruto run long distances, climb mountains, or swim across large bodies of water. This would build Naruto's stamina and strength, which are crucial in battle. Additionally, Jiraiya could teach Naruto advanced ninjutsu techniques, like new ways to use his Rasengan or how to combine different elemental jutsus.
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.
You can start by looking on popular fanfiction websites like FanFiction.net or Archive of Our Own. They have a large collection of Naruto - related fanfictions, and you can search specifically for ones where Naruto trains seriously.
One great 'naruto trains seriously fanfiction' could be where Naruto trains under a reclusive master. He might learn unique jutsu and develop his skills in a way different from the original series. For example, he could focus on combining nature chakra in new ways during his training.
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.
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.
In some fanfictions, Naruto's serious training after Mizuki might lead to him rapidly improving his skills. He could master new jutsu faster, like developing a more powerful Rasengan variation. His physical strength and endurance would also increase significantly, allowing him to better handle difficult missions.
