There could be a new ninja created specifically for this fanfic. This ninja might be the one fated to wield the sword with the soul. Alongside them, characters like Kakashi could be involved. Kakashi, being a skilled and experienced ninja, could serve as a mentor to the new character. He could help them understand the nature of the sword's soul and how to control its power. And of course, villains from the Naruto series like Orochimaru might also make an appearance, trying to get their hands on the powerful sword for their own evil purposes.
It might have Sasuke as one of the main characters. Given his quest for power, he could be drawn to the sword with the soul. He might try to steal it or form an alliance with the wielder to gain access to its power. Another possibility is that it could introduce an entirely new character who is the rightful owner of the sword's soul, and the story could be about this character's journey to reclaim the sword and use it for good in the Naruto world.
Well, it could be Naruto himself, but with new abilities related to soul magic. He might be the one to discover this new form of magic and use it to protect his village in a different way.
It could be Sasuke too. He has a complex character arc in the Naruto series, and in a fanfic about a soul's home, his search for meaning or a place of belonging could be explored. He might be one of the main characters in this fanfic.
Since it's a Naruto - related fanfic, Naruto himself is likely to be one of the main characters. There might also be other characters like Sasuke or Sakura who could be involved in the story related to the Sword of the Angels.
It could be Naruto himself. Since it's a Naruto - related fanfic and the sword is involved, he might be the main character trying to either obtain or protect the Sword of Totsuka.
In the 'Soul Sword Novel', the main characters might include a group of adventurers. One of them could be a female warrior who is strong and fearless and has a special connection with the Soul Sword. There might also be a thief - turned - good - guy who uses his skills to help the group protect the sword. And then there could be a powerful sorcerer who tries to unlock the full potential of the soul within the sword.
Urahara Kisuke would be a great addition. His mysterious nature and vast knowledge could either help or hinder Naruto. Yoruichi could also be a main character. Her cat - like abilities and combat skills would make for some exciting interactions with Naruto. She could teach Naruto some new moves or they could team up against a common enemy.
I'm not sure exactly as I haven't read it. But generally, a Naruto fanfic with'soul of the sword' in the title might be about a special sword that has a soul or spirit in the Naruto universe. It could involve a character finding this sword and having adventures related to it, like unlocking its powers or using it to fight powerful enemies.
Obviously, Naruto would be one of the main characters. Since it's a Naruto - centric fanfiction with the dragon soul element, he's likely to be at the center of the story, dealing with the powers and responsibilities that come with the dragon soul.
It could be Naruto himself. Since he has such a complex backstory and has faced a lot of hardships, it's likely that he could be a main character in a story about broken souls.
Sasuke is an obvious choice. He's already associated with swords like the Kusanagi. A fanfic could explore his further development with the sword, perhaps unlocking new abilities or techniques.
