Yes, there might be. Some fanfics like to give Naruto new abilities and having him quickly master Rokushiki could be an interesting plot point. Writers often enjoy exploring how a character from one universe would adapt to skills from another.
A possible storyline is that Naruto accidentally stumbles upon a hidden dojo where Rokushiki is practiced. The dojo master, seeing Naruto's potential, takes him in as a student. As he learns Rokushiki, he has to face the challenges of combining it with his ninja skills. He might also face opposition from some of the other students who are jealous of his natural talent. This could lead to various conflicts and growth for Naruto's character within the fanfic.
In a fanfic where Naruto knows the Chidori, it could change the power dynamics in battles significantly. Naruto's already vast chakra reserves combined with the piercing and fast - acting nature of the Chidori would make him an even more formidable opponent. He could use it in close - quarter combat situations, perhaps integrating it with his Shadow Clone Jutsu in creative ways. For example, he could have clones perform the Chidori from different angles, catching his enemies off - guard.
Definitely Sasori. He has that whole tragic backstory of turning himself into a puppet. In fanfic, he can be portrayed in different ways, like being redeemed or having even more powerful puppet - making skills. Kankuro is also up there. He's shown in the series to be quite talented with puppets, and in fanfic, he might be involved in epic battles or be the mentor to a new generation of puppet masters. There are also some fan - created puppet masters that gain a lot of fame in certain fanfic communities. These are often characters with unique abilities or backstories related to puppetry.
In addition to the original Naruto characters, there could be new characters introduced in the fanfic. Maybe a mysterious sage who has some connection to Naruto's all - knowing ability. However, the main focus would still be on Naruto and his friends from the original series. His knowledge would change the dynamics between them. For example, Naruto might know things about Kakashi's past that could strengthen their bond or create some interesting plot twists.
It depends on the specific plot of the fanfic. Sometimes he could be on a secret mission, in a hidden village, or facing a new challenge in an unknown location.
One interesting story could be Naruto using his all - knowing ability to prevent a major war. He might foresee the plans of the enemies and be able to take steps to stop them before they even start plotting. For example, he could figure out Orochimaru's next move and stop his experiments on innocent people.
His training would probably be more advanced. Since they know his connection to the fourth, they might give him access to special jutsus and training methods that were reserved for the elite.
It depends on the specific plot of the fanfic. Sometimes Naruto might be at the village, on a mission, or in a hidden place.
Often, they blend the ninja - based world of Naruto with the concept of conquering hearts from 'The World God Only Knows'. For example, Naruto might use some mind - influencing techniques similar to those in the other series. Another feature is the crossovers of characters. We might see some characters from 'The World God Only Knows' interacting with Naruto and his friends in the Hidden Leaf Village.
If Konoha knows Naruto is the fourth one in this fanfic, it would have a far - reaching impact. Firstly, Naruto's self - perception would be different. He wouldn't have to strive so hard for recognition. The plot would deviate from the original in many ways. The Akatsuki's view of Naruto might change as well, as they would be more cautious dealing with someone with such a connection. Konoha's internal politics could also be affected. There might be different factions trying to influence Naruto or use his connection to the fourth for their own purposes. His relationships with the Hokage lineage would be more open and complex, and he might be involved in Konoha's top - level decision - making at an earlier age.
