Naruto would most likely be one of the main characters. Given the title, there might also be some original vampire characters created specifically for this fanfiction.
Obviously, Naruto would be one of the main characters since it's in the title. He's the one with the 'vampire god' transformation. There might also be his friends like Sasuke and Sakura. Sasuke could be either a rival or an ally in Naruto's new vampire - related adventures. Sakura might be concerned about Naruto's change and try to help him control his new powers.
Well, Naruto is probably the central character as the title implies he has a significant role as the 'first vampire'. Other characters from the Naruto series like Sasuke or Sakura could also be important. They might be involved in Naruto's transformation into a vampire or they could be trying to help him deal with his new state. And of course, there could be some powerful vampire antagonists who play a major role in the story.
I'm not sure about the specific plot of this fanfiction as there could be many different interpretations. It might involve Naruto characters in a world where vampires exist, perhaps with Naruto having some new powers related to vampirism or facing off against vampire enemies.
Most likely Naruto would be one of the main characters since it's a Naruto fanfic. He is usually the central figure in any Naruto - related story.
It could be Sasuke. Since the fanfic has 'Sharingan' in the title, Sasuke, who is well - known for his Sharingan abilities in the original Naruto series, might be one of the main characters.
There might also be a mentor figure, someone who has taught the ultimate swordsman their skills. This character could be an old and wise ninja with a lot of experience in swordsmanship.
Maybe there are some non - fairy characters as well, like a human who accidentally stumbles into the fairy world and becomes involved in their adventures. This human character could bring a different perspective and add an element of novelty to the story.
Naruto and Shinso are the primary ones. But we could also have an old and wise vampire elder as a main character. This elder could have knowledge about a prophecy that involves Naruto and Shinso, and his actions and decisions would drive a lot of the plot as he tries to either fulfill or prevent the prophecy.
There could be a team of trainers. One might be a strong and experienced trainer who has a deep connection with a powerful Pokemon. Another could be a more tech - savvy trainer who helps figure out how the ultimate weapon works. And perhaps a young and naive trainer who is there to learn and grow throughout the story. There may also be an antagonist, like a powerful Team Rocket - like organization leader who wants the weapon for evil purposes.
Well, the main characters are usually Silver and Blaze. Silver, who might be portrayed as a vampire with his own set of powers and weaknesses. And Blaze, who could be a love interest, a fellow vampire, or a mortal caught up in the vampire world.
