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. It could explore how he uses these new powers in battles or how it affects his relationships with other characters like Sasuke or Sakura.
Obviously Naruto would be one of the main characters since it's about him being the son of Amaterasu. Other likely main characters could be his friends like Sasuke and Sakura. They would play important roles in Naruto's journey as he discovers and deals with his new identity.
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.
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.
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.
Naruto in this fanfiction would likely have a different sense of self - identity. He's used to being a ninja from Konoha, but now as the son of Amaterasu, he has a whole new heritage to grapple with. He might be more confident in his abilities, as he has this divine blood in him. Also, his relationships with others could change. For instance, he might be more cautious around devils, given his divine origin, but also be more curious about their ways compared to his original Naruto self.
He'd be more confident. With Zeus as a father, he might inherit that godly self - assurance. And the power from Amaterasu would make him more intimidating. So he'd probably be less hesitant in battles.
It's possible that he has the power to summon creatures related to Amaterasu. Maybe some sort of fire - spirit or a mythical beast associated with the goddess. And from Naruto, he could inherit the ability to enter Sage Mode, which would further enhance his combat capabilities when combined with his fire - based powers.
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.
