Kakashi could also play a major role. He has a wealth of knowledge and experience, and could guide the son in his training. And then there's Tsunade. As the Hokage, she might be involved in decisions regarding the son's presence in the village and could also offer her medical expertise when the son gets injured during his adventures. There could also be some of the tailed beasts as characters, as they have their own powers and could interact with the son in various ways.
Well, it could be about the son of a Shinigami and a Kami in the Naruto universe having to deal with the complex politics and power struggles between different clans and villages. Maybe he has unique powers from both his parents that make him both feared and respected.
Obviously, the son of Kami would be a main character. And some Shinigamis would also be important. Naruto and his friends could also be main characters as they are part of the Naruto universe. They might interact with the son of Kami and the Shinigamis in different ways.

His existence could disrupt the existing power dynamics. He might have abilities that are a blend of Kami - like powers and something unique to him. The story could explore how the ninja world reacts to his presence, how he forms alliances or rivalries, and how his story unfolds in the context of the Naruto universe filled with ninjas, jutsus, and hidden villages.
Obviously, Naruto is the main character since it's about him being the son of Kami. But other important characters could include his friends like Sasuke and Sakura. They might play a role in how Naruto copes with his new identity.

One character could be Jiraiya. He could have known something about Naruto's true heritage all along and be the one to finally reveal it to Naruto. From the Greek side, Triton, Poseidon's son in mythology, could be a character. He could either be a rival or an ally to Naruto. In the ninja world, Shikamaru might be involved. His intelligence could be used to help Naruto understand and strategize with his new powers, especially when dealing with any threats that come his way because of his connection to Poseidon.
One possible antagonist could be those in the ninja world who fear Naruto's new - found power. They might see him as a threat to the existing power structure. For example, some of the more traditional ninja clans could be against him.
Perhaps there's a group of magic - wielding ninjas who are either friends or foes. They could have different types of magic, like earth - magic ninjas or wind - magic ninjas. And there might be a powerful sorceress who has a connection to Naruto's family and she could play a key role in his journey to understand his magic.
There might be a friend of Alucard's son. This friend could be a normal human who has no idea about Alucard's true nature. He could be the one who encourages Alucard's son to seek out his father and be there for him during the difficult process of getting to know Alucard.
Samul, of course, since he's Naruto's supposed father in this fanfic. He could be a powerful ninja who had some great influence in the past. Another character could be Naruto's mother, who might have a different story now considering her relationship with Samul. Also, characters like Jiraiya could still play an important role.
