In Naruto fanfiction, how could Kisame's sword be a major plot device in a story with Naruto?

Well, in some fanfictions, Naruto might defeat Kisame in a battle and take the sword as a trophy. Maybe he uses his newfound Sage Mode powers or some other advanced jutsu to overpower Kisame and claim the sword.

The plot could involve Naruto getting the sword as a gift from an unexpected source. With Kisame's sword in his possession, Naruto becomes a target for many who either want the sword for themselves or fear the power it could give Naruto. Naruto then has to protect the sword while also trying to master it. He might seek out old sword - masters in the ninja world to train him. Along the way, he could face off against enemies who are also after the sword, and his friends might be in danger because of it.

In this fanfiction, perhaps Naruto is on a quest to learn more about Kisame. He could meet people who knew Kisame and through them, uncover secrets about his supposed father. This could lead to him having to make difficult decisions, such as whether to follow in Kisame's footsteps in some aspects or completely break away and forge his own path as a ninja.

The plot could involve Naruto being shunned by the Hidden Leaf Village for some reason and Kisame, seeing an opportunity, takes him in. Kisame might see Naruto as a tool at first, but as time passes, he develops a sort of father - son bond with him. Naruto would then have to deal with the fact that he's now associated with the Akatsuki, which would put him at odds with his former friends. He could use this new position to try and change the Akatsuki from within, with Kisame's begrudging support.

Well, it could be that Naruto's relationship with the other Konoha ninjas changes drastically. They might see him as an outcast because of his association with Kisame. On the other hand, Naruto might try to bridge the gap between Konoha and the Akatsuki due to his upbringing by Kisame. This would create a whole new set of conflicts and alliances within the Naruto universe.

One interesting plot could be that Naruto discovers a hidden power within Kisame's sword. Maybe during a battle, the sword starts to react to Naruto's chakra in an unexpected way, leading to a new form of combat for Naruto.

She could start off as an enemy to Naruto's friends, but as she gets to know them better, she becomes more friendly. For example, she might initially be sent to spy on Sakura, but ends up respecting her medical skills. With Shikamaru, she could engage in strategic battles of wits. And with Choji, she might be intrigued by his unique eating habits and the power it gives him.

The plot could involve Naruto using Samehada to gain an understanding of the Akatsuki's motives. Since Samehada has a connection to the Akatsuki through Kisame, it might hold some secrets. Naruto could use it to track down other Akatsuki members or find out more about their plans.

However, it might also attract unwanted attention. Other villains or even some of the shinobi villages could see Naruto with Kisame's sword and assume he has some sort of alliance with Kisame or the Akatsuki. This could lead to him being targeted or distrusted by others.

At first, it would be full of suspicion. Naruto is a Konoha ninja and Kisame is from the Akatsuki. But as the teaching progresses, they might develop a mutual respect. Naruto would respect Kisame's power and knowledge, and Kisame might respect Naruto's determination.
