It would be really dark. Naruto would have to hide his true beliefs from everyone around him. He might be involved in some really strange and cruel practices in secret, which would be a huge contrast to his friendly and positive image in the original series.
Well, it's very possible. In the realm of fanfiction, authors have the freedom to re - imagine characters in all sorts of ways. A fanfiction where Naruto is secretly a Jashinist might explore how he hides this from his friends and the village. It could also show the internal struggle he has between his new - found (secret) beliefs and his loyalty to the Leaf. Maybe there are some events that pushed him towards this path, like a sense of being an outcast or a misunderstanding of the Jashinist philosophy. It would be an interesting and controversial take on the character for sure.
In some fanfictions, Naruto might be depicted as a Jashinist, but this is a departure from the original Naruto canon. Fanfiction allows for creative and often out - of - the - box interpretations of characters, so it's possible for such a concept to exist in the world of fan - created stories.
Well, in this fanfiction, Naruto might idolize the Sannin secretly. He could be trying to learn their unique jutsus on his own. Maybe he secretly practices Jiraiya's toad summoning or tries to imitate Tsunade's super strength. He might even study Orochimaru's snake - related techniques in a more positive light, like for self - defense or to protect the village.
Another option is to ask other Naruto fans directly. You can join Naruto - related forums or groups and post a question asking for recommendations on 'Naruto Jashinist fanfiction'. Fans are often happy to share their favorite finds, and this way you can get some really good suggestions that might not be as easily found through general searches.
One implication is a change in his moral compass. Jashinists are often associated with dark and violent practices in the Naruto universe. So if Naruto is a Jashinist in fanfiction, it means he could be involved in actions that go against his original kind - hearted nature.
There might be a fanfiction where a Jashinist character forms an unlikely alliance with Naruto. This could lead to some really interesting character development as Naruto tries to understand their beliefs. It might also involve battles where the Jashinist's unique abilities are put to the test.
In some Jashinist Naruto fanfiction, the Jashinist character might be on a quest for power. They see Naruto as a potential source of power or a threat to their plans. For example, they could believe that Naruto's unique chakra could be used in their Jashinist rituals. This could create a complex plot where Naruto has to figure out the motives of the Jashinist while also dealing with other threats to the village. There could also be a story where a Jashinist forms an unlikely alliance with Naruto against a common enemy, and through this alliance, they both learn something about each other's worlds.
One possible plot could be that Naruto, disillusioned with the traditional ninja ways after facing some great betrayal in the village. He stumbles upon the teachings of Jashinism. At first, he's hesitant, but as he delves deeper, he starts to see the power it could offer him. He begins to adapt their rituals and beliefs, which causes a huge rift between him and his former friends. His new path makes him a target for those who oppose Jashinism in the ninja world, leading to many battles and a complex web of relationships being torn apart and rebuilt in new and unexpected ways.
Naruto could be gathering intelligence. Since he can move around freely in many places without arousing too much suspicion, he might be using his friendly and open - natured guise to collect information that Itachi needs. For example, he could be finding out about the movements of other ninja clans or potential enemies of Itachi's plans.
His relationship with Sasuke would likely become very strained. Sasuke, who has his own dark path, might still see Naruto's new Jashinist ways as too extreme. With Sakura, she would probably be very disappointed and try to convince Naruto to return to his old self. As for Kakashi, he would be deeply concerned and might even see Naruto as a potential threat to the village at first.
