Well, it could start with the discovery of the OC's identity as Grayfia's son. This would surely stir up a lot of reactions among the different factions in the Highschool DxD universe. He could be thrust into various adventures, like having to protect a certain character or retrieving a powerful artifact. His relationship with his mother, Grayfia, would also play a significant role, perhaps she has certain expectations of him that he struggles to meet while also dealing with his own desires and goals.
Issei could be a potential ally. He is always getting into adventures and might see the OC as a valuable addition to his group. Also, Rias might be an ally as she is often involved in power plays and could use the OC's connection to Grayfia to her advantage while also providing protection to the OC in return.
Grayfia in this fanfiction might be a powerful figure. She could be a ninja with unique abilities or a non - ninja with influence in the Naruto world. Since she betrays Naruto, she probably has her own set of beliefs and goals that conflict with Naruto's. Maybe she's part of a secret organization or has a personal vendetta against Naruto that we'll find out as the story progresses.
It could be the one who manipulated Grayfia into betraying Naruto. Maybe it's a powerful and cunning villain from Naruto's world or even from another dimension. This antagonist could have a hidden agenda that involves getting rid of Naruto by using Grayfia.
A big characteristic is the exploration of different worlds and cultures. The OC can bring in a whole new set of values and backgrounds, and when paired with Grayfia, who has her own established world in the original story, it creates a contrast. It also allows for the expansion of the existing lore, like adding new magic systems or social hierarchies related to the OC's world.
Since lemon often involves romantic or sexual themes, in Grayfia lemon fanfiction, a common theme could be her relationship with other characters in a more intimate context. But again, this may not be suitable for all audiences.
I really like 'Naruto and Grayfia: A New Beginning'. In this fanfic, Naruto's positive energy and Grayfia's elegance are well - portrayed. It shows how Naruto's unique skills can be useful in Grayfia's world which is full of different power dynamics. There are also some great character development arcs for both of them. For example, Grayfia learns from Naruto's never - give - up attitude.
One good Grayfia Naruto fanfiction could be 'Grayfia in the Naruto World'. It might explore how Grayfia, with her unique abilities from her original context, adapts to the Naruto universe. She could interact with Naruto characters in interesting ways, like perhaps teaching some of them her special magic or combat skills.
Yes, there are some. You can try searching on fanfiction platforms like FanFiction.net or Archive of Our Own. Just type in 'naruto x grayfia' in the search bar and browse through the results.
The plot might involve Naruto growing up in a world that's a mix of Naruto - like elements and High School DxD. Grayfia would be his mother figure, and he'd inherit some of her abilities or characteristics. There could be a conflict where Naruto's original ninja values clash with the values of the new world. He might also have to face enemies who are after him because of his connection to Grayfia. And as he grows, he discovers more about his true identity and his place in this strange new world.
