In a Naruto x Rias High School DxD fanfiction, Naruto could bring his unique ninja abilities to the table. His shadow clone jutsu could be a real game - changer in the battles against the devils and other supernatural beings in the High School DxD universe. Rias, on the other hand, could introduce Naruto to the complex politics and hierarchies of her world. Their relationship could be a mix of mutual respect for each other's powers and a growing attraction. Maybe Naruto would initially struggle to adapt to the more risqué aspects of the High School DxD world compared to his relatively more conservative ninja world.
One possible idea for this fanfiction could be Naruto being transported to the world of High School DxD. He might end up attending the same school as Rias. Given Naruto's strong sense of justice and his combat skills, he could quickly become involved in the supernatural battles and power struggles in that world. He might also form an interesting relationship with Rias, perhaps starting as friends and gradually developing into something more as they face various challenges together.
In a Naruto and High School DxD crossover fanfiction involving an archangel, it could be really interesting. Maybe the archangel has powers that are similar to some of the shinobi abilities in Naruto. For example, the archangel might have a 'heavenly chakra' that is like the normal chakra but with more divine properties. It could also be that the archangel has a role in the DxD world similar to Naruto's role in his own world, like a protector or a catalyst for change.
Another possibility is that there is a tournament that spans multiple universes. Naruto is selected to represent his world, and Rias volunteers or is chosen to represent the High School DxD world. They meet at the tournament grounds. At first, they might be a bit suspicious of each other, but as they see each other's skills and determination in the battles, they start to respect and eventually become friends, working together to win the tournament for their respective worlds.
Naruto might teach some of his ninja skills to the students in the High School DxD. For example, his tree - climbing and water - walking techniques could be really interesting for them to learn. Rias could be intrigued by Naruto's determination and his never - give - up attitude. She might see him as a valuable addition to her peerage. And in return, Naruto could be fascinated by Rias's devil powers and the way she manages her group. They could also have some cultural clashes, like Naruto's more simple and straightforward ninja culture compared to the complex and often flamboyant devil culture in High School DxD.
One possible reason for such a fanfiction could be to explore a different dynamic in the story. Maybe the author wants to show a more complex relationship where Issei has some deep - seated issues with Rias' leadership style or her decisions. It could also be a way to create conflict and drama, which are essential elements in fan - created stories.
There could be a storyline where Naruto is summoned to the High School DxD world by some ancient magic. He is seen as a powerful ally or a threat depending on who you ask. Rias takes it upon herself to figure out Naruto's intentions. As she gets to know him, she realizes that his values of friendship and protecting the weak are similar to her own. Together, they start a journey to stop a dark force that is rising in the DxD world, with Naruto teaching the devils some ninja techniques along the way.
A great plot could be a tournament - style story in the 'Naruto x Rias High School DxD' fanfiction. The tournament could be a mix of ninja and devil skills. Naruto enters representing his ninja heritage and Rias enters on behalf of the devils. Along the way, they have to face opponents from different factions. As they progress, they start to understand each other better and develop a deeper bond. Naruto's determination to win for the sake of his new friends in the DxD world and Rias's desire to prove the strength of the devils would drive the story forward, and their combined efforts could lead to an unexpected victory.
One potential plotline could be Naruto being summoned to the world of Rias by accident. He then has to figure out how to get back home while also getting involved in the power struggles within the devil world. Maybe he becomes a key player in a battle for control of a certain territory.
He'd probably have a complex relationship with Sirzechs. As Rias's father, Naruto would be protective of his daughter and might be cautious around Sirzechs at first. But given Naruto's ability to see the good in people, they could end up as allies. With Issei, Naruto might see a bit of himself in the young pervert - turned - hero and could offer him some guidance in terms of power and relationships.
Yes, there are some. You can start by looking on fanfiction platforms like FanFiction.net or Archive of Our Own. Some authors create crossovers where Naruto characters interact with the High School DxD universe in a platonic or adventure - based way. For example, they might have Naruto and his friends visit the DxD world to help with a demon - related problem, without any inappropriate content.
In this fanfic, Naruto's unique abilities like his shadow clones and Rasengan could be combined with the magic and powers in the DxD universe. For example, a fallen angel might be interested in Naruto's chakra and try to use it for their own purposes. Naruto, being the hero he is, would not let that happen and would start a conflict that could lead to an epic adventure.
