Naruto and Rias both believe that they are the ones to fulfill this prophecy. So they meet, initially as rivals, each thinking they are the true hero. But as they learn more about each other and the challenges ahead, they realize that they need to work together. This plotline could involve them traveling between the two worlds, gathering allies, and facing off against those who oppose the idea of the two worlds uniting.

In a Naruto and Rias Gremory fanfiction, Naruto's chakra system could interact in interesting ways with the magic in Rias's world. His ability to control and manipulate chakra might be seen as a form of power that the devils would either fear or try to understand. Rias, on the other hand, could introduce Naruto to the political and social aspects of her world. They could also exchange combat techniques, with Naruto showing the devils how to move with the speed and stealth of a ninja, and Rias's group teaching Naruto some devil - specific magic that could enhance his abilities in different ways.
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.

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.

A plot twist might involve Rias having to choose between her duties in the Gremory clan and her love for Naruto.

For example, she might be forced to enter an arranged marriage for the sake of her clan, but she really loves Naruto. This would lead to a complex and emotional storyline.

In the ninja world, his old sensei or comrades who respect his decision to embrace his new identity could be his allies. Also, there might be some mythical creatures in the devil realm that recognize Naruto's pure heart and decide to fight alongside him.
