Since I haven't read it, it's hard to say for sure. But it could be the usual Naruto characters like Naruto himself, Sasuke, or Sakura if the demon blade is something that gets involved in their storylines. Maybe there's a new character introduced specifically for this fanfic who is the one directly related to the demon blade, like a wielder or a protector of it.
There might be a character who is drawn to the power of the demon blade. It could be a rogue ninja who wants to use it for his own gain. On the other hand, there could be a good - hearted character who tries to keep the blade out of the wrong hands. It's also possible that an older, more experienced ninja from the Naruto world, like Kakashi, could play a role in dealing with the implications of the demon blade.
Well, Naruto is almost always going to be a central figure in a 'mortal blade naruto fanfic'. He has the drive and the power to be involved with such a powerful and mysterious object like the mortal blade. Sakura might also play a more prominent role, maybe as a healer who has to deal with the consequences of those who use the blade. Another possible main character could be a rogue ninja who is after the mortal blade for his own evil purposes. He could serve as the main antagonist in the fanfic, constantly causing trouble for Naruto and his friends.
I think Naruto is the central character. His friends, such as Kakashi, who was his teacher, would also be main characters. They would be involved in Naruto's journey of dealing with being labeled as a demon in Konoha. Additionally, any villains or antagonists who oppose Naruto because of his 'demon' status could be main characters. For example, if there are some villagers who are against Naruto and try to drive him out, they could be considered main characters in the context of this fanfic.
Since I haven't read it, I can't say for sure. But it's likely that Naruto could be one of the main characters given that it's in the title. There might also be new characters created specifically for this fanfic, like a demon breeder character who could be central to the story.
Obviously Naruto would be one of the main characters since the title mentions him. There might also be characters like Kakashi who could be guiding Naruto through this situation with the demon in the lake.
Well, Naruto would obviously be the main character as the story is centered around him being a half - demon. There might also be characters like Sasuke. Sasuke could be involved in Naruto's journey, perhaps initially being suspicious of Naruto's new powers but later coming to accept and even help him control them.
Obviously, one of the main characters would be the demon. Another would be the princess. And depending on how the story is written, Naruto and some of his friends like Sasuke or Sakura might also be important characters as they could be involved in the events related to the demon and the princess.
Obviously, Naruto would be one of the main characters. There might also be some original characters created specifically for this fanfic that are from the demon village. They could be demon villagers with unique powers or personalities.
Well, obviously Naruto and Blade are main characters in most of these fanfictions. Naruto brings his ninjutsu skills, his never - give - up attitude, and his dream of becoming Hokage. Blade, on the other hand, has his superhuman strength, speed, and his weapon skills. He also has his vampire - like powers which make him a very unique addition to the Naruto universe.
Obviously, Naruto would be one of the main characters. He's the protagonist of the Naruto series, so it's very likely he'll play a central role in the fanfic. Sasuke could also be a main character as he often has his own story arcs that intersect with Naruto's. And maybe Sakura too, since she's part of the main trio. There might also be some new characters introduced specifically for this fanfic related to the Dragon Blade, like a mysterious ninja who has a connection to the blade's history.
Main characters in naruto demon harem fanfic are Naruto, who is in the middle of all the action. Female characters such as Temari from the Sand Village might also be included. And the demon, which is what makes it a 'demon harem' fanfic. The demon might have its own motives and goals, which often clash with Naruto's. The female characters are caught in between, having their own feelings for Naruto and being affected by the presence of the demon. This complex web of relationships is what drives the story forward.
