Naruto's strong sense of justice and his unwavering determination to protect the village could also play a role. He has shown time and again that he would sacrifice anything for Konoha. His moral compass and his courage in the face of danger could be seen as qualities befitting a Jounin, even at a young age.
In this fanfiction, Naruto might become a Jounin at a young age due to his extraordinary growth. Maybe he has a special training regime with a powerful mentor. His quick rise could also be because of a new and powerful jutsu he discovers. This would make the village elders recognize his strength and promote him early.
Maybe Naruto has some secret training that accelerates his progress. For example, he could have found an ancient scroll or received special guidance from a hermit - like figure. This extra training gives him an edge over others, allowing him to meet the requirements for jounin at a young age.
If Naruto becomes a Jounin early in fanfiction, his relationship with his peers might change. They could look up to him more, seeing him as a role model. His friends like Sasuke might be a bit jealous at first but would also be proud. His relationship with his teachers could shift as he is now closer to their rank.
In terms of his romantic relationships, if there was a budding relationship with Hinata, for instance, his new status as a jounin could either strengthen their bond as she admires his achievement, or it could create some distance as he has more duties and less time for personal matters.
One consequence could be that he faces a lot of envy from his peers. Many ninjas who have been training for years might feel resentful that Naruto, who is much younger, has achieved such a high rank. This could create some tension within the village.
Perhaps Naruto, as a young Jounin sensei, has to deal with a student who has a dark past similar to his own. He has to figure out how to help the student open up and trust him. Naruto uses his own story of growing up alone and being shunned by the village at first to connect with the student. He shows the student that they can rise above their past and become a great ninja.
Perhaps the plot could revolve around Naruto's internal struggle. Even though he has achieved the Jounin rank, he still doubts his own abilities. He could face challenges from other Jounin who don't believe he's worthy of the rank. Meanwhile, he discovers a new and dangerous enemy that is targeting Konoha's Jounin. Naruto has to overcome his self - doubt and use his skills, like his Rasengan and Sage Mode, to defeat this new threat and prove his worth as a Jounin.
One common theme is growth. Since Naruto is now a young jounin, he has to grow into his new role. Another theme is leadership. He has to lead his team and make tough decisions. And also, there's often the theme of self - discovery as he figures out how he fits into the ninja world at this new level.
Yes, in some fanfictions Naruto can be depicted as a Jounin. Fanfiction allows for creative interpretations of the Naruto universe, and it's not uncommon for writers to accelerate Naruto's growth and have him reach the Jounin rank earlier than in the original series.
