Well, considering the title, there might be a lead shinobi character who is highly skilled and brave. Maybe there are also some supporting characters like a wise old shinobi mentor or a young apprentice. And since it's set on the high seas, there could be some non - shinobi characters as well, such as a ship captain or a mermaid who interacts with the shinobi in different ways.
Another possibility is that there are rival shinobi groups in the story. One group could be the protagonists, trying to achieve a certain goal, while the other group might be antagonists, causing trouble for the main shinobi characters. Without reading the fanfiction, we can only speculate about the main characters.
Since it's a Naruto - related fanfic set in the high seas, Naruto is bound to be a central figure. His determination and powerful jutsu would play a key role. However, other characters from the Naruto world would also be involved. For instance, Rock Lee could be there, showing off his unique taijutsu skills on the ship decks or against enemies in the water. And Hinata might be part of the story too, perhaps using her Byakugan to detect hidden threats in the vast ocean or on uncharted islands.
I'm not sure specifically as I haven't read it. But generally, 'shinobi' might refer to ninja - like characters. It could be a fan - made story set on the high seas involving such characters with some unique plot twists and adventures.
It could be about Naruto characters in a high - seas adventure setting. Maybe they're on a ship, facing pirates or other sea - related challenges, while still using their shinobi skills.
Obviously Naruto is one of the main characters since it's in the title. He is likely to be the central focus of the story as the last shinobi.
There could be new characters as well. The fanfiction might introduce some young shinobi who are the last hope of the shinobi world. These new characters could have unique abilities and backstories, and they might learn from the older, more experienced shinobi. They could be mentored by the likes of Kakashi or Guy.
Obviously, Naruto would be the main character as it's about him being the 'god of shinobi'. But there could also be other characters like Sasuke, who might be in a different relationship with Naruto now that he is a god - like figure. Sakura could also play a role, perhaps as a healer trying to understand Naruto's new powers.
The main characters could be a combination of well - known Naruto characters and new ones made for the fanfic. Maybe a Kiri shinobi could be a main character, someone with a unique backstory and abilities. It could also have characters from other villages who come to Kiri for some reason, like a joint mission or to seek refuge. And of course, there might be some antagonist characters within the Kiri village who create conflict for the protagonists.
I don't know for sure, but it could be a young and talented shinobi who is the protagonist.
Harry Potter would be a central character. There may be some original shinobi characters created specifically for this fanfiction. His Hogwarts professors could also play important roles, perhaps being involved in the shinobi training or having some sort of connection to the shinobi world. And of course, if there are any antagonists, they could be from either the wizarding or the shinobi side, or a combination of both, making for some really interesting conflicts.
In many 'naruto kami no shinobi fanfiction', Kakashi could play an important role. He might be the one guiding Naruto in understanding the ways of the kami, as he has a vast knowledge of different jutsus and the ninja world in general. Also, characters like Hinata could be involved. Maybe she has some sort of connection to a kami as well, which could lead to a new relationship dynamic with Naruto.
