In some fanfictions, Naruto can be made into Rias' boyfriend through creative writing. Fanfiction allows for crossovers between different fictional universes, and writers can imagine unique relationships. However, in the original Naruto and High School DxD (where Rias is from) storylines, there is no such relationship.
Yes, there are likely fanfictions with this premise. In the Naruto fan community, fans often come up with various creative pairings. Some writers might be interested in exploring a relationship between Naruto and Anko, imagining how their personalities would interact, what kind of adventures they could have together, and how their relationship would develop within the Naruto universe.
It might also be Gaara. Their initial encounters were filled with tension, but as the story could be twisted in fanfiction, that could develop into a different kind of relationship. Gaara's own journey of self - discovery and Naruto's influence on him could be a basis for a romantic relationship in fanfic.
Well, it's somewhat common. Fanfiction gives fans the freedom to play around with the characters' relationships. For Naruto, having a boyfriend in fanfiction can be a way to appeal to those who want to see diverse relationship dynamics. However, it's not the most mainstream type of Naruto fanfiction. There are many other popular themes like Naruto's growth as a ninja, his friendships, and his battles that often overshadow this particular relationship - themed fanfiction.
If Anko had a boyfriend, it might change her interactions with other characters and influence her development. Maybe it would bring out new sides of her personality or create conflicts and resolutions.
If Naruto was Rias' boyfriend in fanfiction, there would be a huge cultural clash at first. Naruto comes from a world of ninjas and honor, while Rias is in a world full of demons and magic. But as they get closer, Naruto could teach Rias about loyalty and never giving up. And Rias could introduce Naruto to the more complex social and magical aspects of her world. Their relationship could also change the power dynamics in the High School DxD world as Naruto is extremely powerful in his own right.
Naruto might initially think it's a joke. He's used to Sakura being a bit unpredictable, but when he realizes she's serious, he could feel a bit pressured. He doesn't want to hurt her feelings, but he also doesn't want to lead her on. So he might try to avoid her for a while until he figures out how to handle the situation. He might also talk to his other friends, like Shikamaru, for advice on how to deal with Sakura's newfound belief.
It could change the dynamics between the characters. For example, if Naruto's secret boyfriend was Sasuke, it would add a whole new layer to their already complex relationship. The reactions of other characters like Sakura would be very different. She might feel betrayed or confused.
One possible plot could be that Naruto and Anko start off as friends who gradually realize their feelings for each other. They could go on missions together and protect each other, which deepens their bond. For example, they might be on a mission to infiltrate an enemy base, and through their combined efforts and trust in each other, they survive and realize they love one another.
In a modern AU, Naruto as a boyfriend would be an adventure. He'd be super enthusiastic about trying new things. He'd introduce you to his friends, who would become like a second family. He's not the most sophisticated, but his genuine nature makes up for it. He'd probably text you a million times a day just to check in and tell you how much he misses you when you're apart.
