I'm not entirely sure as I haven't read it specifically. But generally in Naruto fanfictions, it could involve new adventures of Naruto with a special black blade, perhaps facing new enemies or exploring uncharted areas of the Naruto world.
Naruto is likely to be one of the main characters since it's in the title. There might also be characters like Sasuke or Sakura who could be involved in the story related to the black blade.
Naruto himself is often a popular character in these fanfictions. He might be the one who wields the black blade and uses it to fight against powerful enemies, bringing his usual determination and spirit to the story.
One interesting plotline could be the origin of the black blade. Maybe it's a weapon created by an ancient shinobi clan with a special power. For example, it could be a blade that absorbs the chakra of those it cuts, making the wielder stronger.
Definitely. There's a fanfic where the black blade allows Naruto to access a special chakra mode. This mode not only makes him stronger but also gives him the ability to sense his enemies' moves before they make them. It's a really cool power - up and changes the dynamic of his battles. In this fanfic, the black blade is like a key to unlocking Naruto's hidden potential.
Perhaps in the 'black blade naruto fanfic', the black blade has a connection to an ancient and forgotten clan. Naruto, being the main character, then delves into the history of this clan, uncovers secrets, and uses the knowledge and power associated with the blade to protect the Hidden Leaf Village from a looming threat that only he with the black blade can face.
Another possibility is a powerful shinobi from a rival village who believes that the black blade should belong to their village. They see Naruto as an unworthy wielder and will stop at nothing to take the blade from him, leading to a series of battles and political tensions between the villages.
Perhaps it's passed down to him by a mysterious figure. This figure could recognize Naruto's potential and believe he's the right one to wield the dragon blade. The figure might be an old ninja who has been protecting the blade for years and now sees Naruto as the savior of the ninja world who needs this extra power.
Maybe in the fanfiction, Fem Blade is on a mission to find a powerful artifact that has been lost in the Naruto universe. Naruto gets involved when he discovers that this artifact could potentially be used to destroy his village. They start off as enemies but as they learn more about each other's motives, they form an alliance and a deep friendship. Along the way, Naruto helps Fem Blade understand the concept of friendship which she has never really experienced before.
