One possible plot could be that Naruto somehow gets transported to Ophis' world. At first, they might be at odds due to their different natures. But as they start to understand each other, a relationship forms. Naruto could use his ninja skills to protect Ophis from threats in her world, and Ophis might offer Naruto some unique power or knowledge in return. Eventually, they get married and have to deal with the political and social implications of their union in both of their worlds.
There could be. Naruto is a very popular character and fanfiction writers love to pair him with all sorts of characters, including those from different universes like Ophis. But it's hard to say exactly what such a fanfiction would be like without actually reading it. It might involve Naruto's world of ninjas and Ophis' characteristics being blended together, perhaps with Naruto having to deal with new challenges due to his relationship with Ophis.
At first, Naruto might see Ophis as a powerful ally he needs to understand in order to protect his world. He would try to approach her with respect. Ophis, seeing Naruto's pure heart, would allow him closer. They would then go through various challenges together, like facing enemies that threaten both their existences. During these trials, they would rely on each other, and Naruto's positive attitude would start to melt Ophis' cold exterior. Their bond would strengthen over time until they realize they can't live without each other and decide to get married.
They could also have a mentor - mentee relationship in a way. Naruto, with his experience in combat and growth, could offer advice to Ophis on how to better control her power. Ophis, with her knowledge of the DxD world's magic and power systems, could teach Naruto some new skills or ways to enhance his chakra. This exchange of knowledge and experience would create a unique dynamic between them.
One interesting Naruto and Ophis romance fanfiction could be 'A New Bond'. In this story, Naruto discovers a strange portal and ends up in Ophis' world. Their initial encounters are filled with confusion but gradually turn into a deep connection. Another good one is 'The Unlikely Pair'. It shows how Naruto's positive attitude starts to influence Ophis and they develop feelings for each other through various adventures.
Yes, there might be such fanfictions out there. Fanfiction often combines different fictional universes in creative ways. However, not all of them are well - known or of high quality. Some might be more focused on the unique interactions between the characters from Naruto and Highschool DxD, exploring how their different powers and personalities would mesh in an unexpected relationship.
The exploration of different worlds or dimensions is also a theme. Since Ophis has connections to different realms, fanfictions often take Naruto and Ophis on adventures through these strange and new places. This allows for a lot of creativity in terms of world - building and the discovery of new and unique things.
In a Highschool DxD - Naruto crossover fanfiction with Ophis, she could form an alliance with some of the Akatsuki members. They might be interested in her power and knowledge. Ophis could use this opportunity to learn about the unique chakra system in Naruto. This could lead to a series of battles and power - up scenarios as she tries to adapt to this new world and the Akatsuki tries to use her for their own goals.
In this fanfiction, perhaps Naruto is transported to a dimension where Ophis is a powerful figure. Naruto, with his strong sense of justice, tries to understand Ophis' motives. He may initially be in awe of her power but then realizes that there are some dark aspects to her actions. He then has to decide whether to side with her or oppose her while also trying to find a way back to his own world.
One main theme is power. Naruto already has his own set of powers, and when combined with Ophis' abilities, the exploration of new power levels and how to control them is a big part. For example, in some fics, Naruto might struggle to master a power given by Ophis.
