Is there a fanfiction where Naruto is the older brother of Issei?

It could be full of action. Naruto would bring his ninja skills to Issei's world. He might train Issei in combat, much like he trained with Sasuke and others. Their relationship could also be full of brotherly banter and support.

Well, in the vast world of fanfiction, it's very possible. Some writers enjoy mixing different fictional universes and creating new family dynamics within them. If Naruto were Moka's older brother in a fanfiction, it could bring about a whole new set of adventures. For example, Naruto's ninja skills and Moka's vampire powers could combine in interesting ways to face various threats. But to actually find such a fanfiction, you should start by looking for crossovers between the Naruto and Rosario + Vampire fandoms on major fanfiction platforms.

Yes, there are likely some fanfictions out there with such a concept. Fanfiction writers often come up with creative crossovers like this. However, the quality and nature of such fanfictions can vary greatly. Some might focus on how Naruto's ninja skills could influence Erza's world in Fairy Tail, while others could explore the family dynamic between them in an interesting way.

Sure, there are likely fanfictions with this premise. Fanfiction thrives on taking established characters and putting them in unexpected situations. If Naruto were Kakashi's older brother, it would completely change the Naruto universe as we know it. It might mean that Naruto would have a different role in Kakashi's life, perhaps being more protective or having a say in his training. Also, it could impact the story arcs that involve Kakashi, as Naruto's presence as an older brother would add a whole new layer of complexity to his decisions and actions.

The older brother in the fanfiction might be a character with a tragic past. For example, he could have been experimented on by Orochimaru and gained some strange powers as a result. And he returns to the village later to protect Naruto from the threats that are coming towards him.

There are quite a few. One popular one is 'Brother's Bond' where Naruto takes on the role of an older brother with great responsibility and care.

There could be. Fanfiction writers like to explore different 'what - if' scenarios. Since Naruto and Kushina have a strong connection in the original series, some writers might be intrigued by the idea of reversing their relationship in a fictional context. But it goes against the established lore of the main Naruto storyline.

In some fanfictions, it's possible for Naruto to be depicted as Anko's older brother. Fanfiction often takes creative liberties with established characters and their relationships.

If Naruto was the older brother of Kushina, it would rewrite a lot of the backstory. For one, Naruto might be the one to introduce Kushina to Minato. He could see Minato's potential and think he would be a good match for his sister. Also, Naruto's skills and abilities could have a different origin. Maybe he learned some things from Kushina or their family that were unique. This would change his fight scenes and how he approaches challenges in the fanfiction. He might also have a different relationship with the Uzumaki clan as a whole, having more of a family - based influence within it.

One idea could be that Naruto, with his strong sense of justice and loyalty, helps Rias in the supernatural politics of her world. He might use his ninja skills to protect her and her peerage from other devils or threats. For example, when facing a powerful rival devil clan, Naruto's shadow clone jutsu could create a diversion while Rias plans a strategic attack.
