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.
The early training would enhance Naruto's ability to empathize. Jiraiya has been through a lot in his life, and he could share his experiences with Naruto. Naruto, in turn, would be able to understand the pain and struggles of others better. This would make him not just a stronger ninja, but also a more well - rounded and compassionate person in the village.
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 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.
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.
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.
Obviously, Naruto and Jiraiya are going to be the main characters. Naruto, the young and energetic ninja - in - training, and Jiraiya, the experienced and somewhat eccentric sage. There might also be some side characters like the villagers of Konoha who could react to Naruto's new relationship with Jiraiya.
Another great piece is 'Naruto: Early Days with Jiraiya'. This fanfiction goes into great detail about the environment when Jiraiya finds Naruto. It not only shows their first meeting but also the reactions of the villagers around them. It then progresses to show how Jiraiya starts to influence Naruto's way of thinking and his training regime, making it a very engaging read.
