One possible plot could be Naruto discovering his divine heritage. He might gain new powers related to Amaterasu Okami. For example, he could have the ability to control some form of sacred fire or light. This would change his relationship with the other characters. His friends might be in awe or a bit scared at first. His enemies would surely see him as an even greater threat.
In this fanfiction, the plot may also focus on how Naruto's new identity affects the ninja world. The villages might react differently to him. Some may see him as a savior, believing that his divine powers can bring peace. Others may fear that he will use his powers to dominate. Naruto would then have to navigate these complex political and social situations while also coming to terms with his own identity.
Naruto's character development might include a deeper sense of responsibility. Since he is the son of Amaterasu Okami, he may feel a greater obligation to protect the world. He could develop new skills not just in combat but also in diplomacy. He has to deal with different factions in the ninja world who have different views on his new status. This would force him to grow and mature in ways he hadn't before.
One plot idea could be a crossover where Naruto gains the power of Amaterasu from Okami. He could struggle to control this new and powerful ability, facing challenges from both within his own village who fear his new power, and external enemies who want to use it for their own evil purposes.
I'm not sure specifically as there can be many different interpretations in fanfiction. It might involve Naruto having some special connection to Okami, perhaps inheriting certain powers or facing unique challenges related to this new heritage.
Well, in this fanfiction, Naruto's origin as the son of Amaterasu could lead to a story where he is initially shunned by some in the DxD world because of his strange powers. But as he proves himself in battles and shows his kind heart, he starts to gain allies. His journey could also be about uncovering the secrets of his mother Amaterasu and how that relates to the overall balance of power in the DxD universe. Maybe he has to face an ancient evil that only his combined ninja and divine powers can defeat.
Well, one possibility could be that Naruto has extraordinary powers due to his divine heritage. He might be able to control both the fire of Amaterasu in a unique way and also possess some of Zeus' lightning or godly strength. Maybe he has to face enemies who are threatened by his existence and his combined powers make him a target. He could also struggle with his identity, being part of two very different mythologies.
Well, it could be about Naruto having some special connection to Amaterasu. Maybe in this fanfiction, Naruto has powers related to Amaterasu that change his journey.

The plot could involve Percy traveling to Japan to learn more about his newfound 'parentage'. There, he meets other Japanese demigods or spirits who either help or hinder him. Maybe he discovers a prophecy that only he, as the son of Amaterasu, can fulfill, which has something to do with saving both the Greek and Japanese mythological worlds from a great threat.
Perhaps he forms a team of his own, like Naruto did with Sasuke and Sakura. His teammates could be from different backgrounds, and together they embark on various missions. His story could also involve exploring the origin of Amaterasu's powers more deeply and how it affects him. He might also have to deal with political situations in the ninja villages, as his existence could change the power balance.
For Naruto, his development could involve learning to master the Amaterasu power from Okami. He might start off being reckless with it, but as the story progresses, he becomes more in control. This could also lead to his growth in terms of how he is perceived by others, from being seen as just a boisterous ninja to a powerful and respected figure with a new, mysterious ability.
Well, it could be about the Son of Amaterasu having to deal with the power struggles in the High School DxD world. Maybe he has some unique abilities inherited from his mother that make him a target or a valuable ally.
