Well, if Naruto had Akame's sword in fanfiction, it could significantly change his combat style. He might rely less on his shadow clones and more on the sword's unique abilities. For example, Akame's sword is known for being able to cut through almost anything. Naruto could use this to his advantage in battles against tough opponents like Sasuke or Pain. He could also incorporate his chakra into the sword, making it even more powerful. This would add a whole new dimension to his fighting and could potentially lead to different alliances and rivalries in the Naruto universe.
Naruto could potentially gain the ability to sense danger more acutely with Akame's sword. In some interpretations, the sword has a certain awareness. This could help Naruto in battles, allowing him to anticipate his opponents' moves better. Also, if the sword has any hidden powers related to Akame's world, Naruto might be able to tap into them. For instance, if there are special enchantments on the sword, he could use them to his advantage, like making himself invisible or resistant to certain types of attacks.

In fanfiction, the sword could have a spiritual power. It might be able to communicate with Naruto on a spiritual level, guiding him in battles or revealing secrets about the past. It could also have the power to create illusions specific to the Cloud Village's history or mythology, confusing enemies and giving Naruto an advantage in combat.
The demon sword could potentially give Naruto new jutsu. Maybe it has some sort of dark energy that he can learn to manipulate and turn into unique attacks. However, he would have to be careful not to let the dark side of the sword overtake him. He might start with simple things like using the sword to focus his chakra in a different way, creating new types of rasengan-like attacks.
The cursed sword could enhance Naruto's physical strength. Since Naruto already has a lot of raw power, the sword might multiply it, making his punches and kicks even more powerful. For example, if he punches an enemy while holding the sword, it could send the enemy flying farther than normal.
