Well, in the Naruto universe, there's no concept of fanfiction. Naruto is busy with his ninja world stuff like fighting bad guys, training, and protecting his village. Fanfiction is something created by fans in our real world, not part of his world. So, he simply can't access it because it doesn't exist in his realm.
Think about it. Naruto's world has its own set of literature and stories, like the tales of the Sage of Six Paths. Fanfiction is something created by fans outside of his universe. He doesn't have the ability to access our world's internet or libraries where fanfiction exists. Also, his upbringing and the nature of his society don't prepare him for such a concept. He's more into learning ninja techniques and fulfilling his duties as a shinobi.
Maybe because in the Naruto world, his training mainly focuses on ninja skills like jutsu and combat, not on literary skills required for reading or writing fanfiction.
It could be that in Naruto's world, fanfiction isn't something that's common or known, so he's never been exposed to it and doesn't have the knowledge.
Well, Pokemon are fictional creatures and don't have the ability to read in the way we understand it. They don't exist in the real world to pick up a Naruto fanfiction and read it. So, the answer is no.
Well, in some fanfiction, the story might be set in an alternate universe where the whole ninja concept doesn't exist. So, Naruto can't be a ninja because there are no ninjas in that world. It could be a world with different power systems, like magic or super technology.
Well, Naruto is a character in his own fictional world. Fanfiction often involves concepts, interpretations, and crossovers that are outside of his original story. He's used to his own established reality in the Naruto series, so these fan - created ideas would be completely foreign to him.
Maybe Neville is too busy with his studies at Hogwarts. He has a lot of magic to learn, like Herbology and Defense Against the Dark Arts. Fanfiction might not be on his radar as he's focused on real magical knowledge.
Maybe he lives in a world where fanfiction doesn't exist or he simply doesn't have access to it. For example, in the wizarding world of Harry Potter, their literature mainly focuses on magic textbooks, historical records of the wizarding world, and some classic wizarding novels. Fanfiction might be a completely foreign concept there.
