Who could be the potential allies of the 'Highschool DxD OC Son of Grayfia' in a fanfiction?

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.

Aang could be an ally. Despite the OC being Ozai's son, Aang, with his forgiving nature, might see the potential for good in the OC. He could help the OC to understand the importance of balance and peace.

His mother Tsunade could be one of his first and most important allies. She would surely use her influence and skills to protect and guide him. Shizune could also be an ally, as she has been with Tsunade for a long time and would likely support the OC. Additionally, Naruto could be an ally, as he is known for befriending and helping out those in need in the ninja world.

The devils who oppose Grayfia's family could be the main antagonists. They might see Grayfia's brother - in - law as a weak link or a potential threat to their power. So they would try to get rid of him or manipulate him for their own gains.

Issei and his group could be potential allies. They are often on the side of good and protecting the balance in the DxD world. Their strength and determination would make them great companions for the Messiah.
