Well, in this fanfiction, it might be that Naruto is given the right hand of the Shinigami as a last resort to defeat a powerful enemy. This could lead to a whole new set of adventures. He may have to learn to control the power, which could be extremely difficult as the Shinigami's power is not of this world. There could be a sub - plot about Naruto trying to keep this power a secret from his friends while still using it to protect them.
Obviously Naruto would be the main character as the title mentions him. There might also be Sasuke, as he often has a role in Naruto - related stories. Kakashi could also be involved, perhaps as a mentor to Naruto in understanding and controlling the power of the Shinigami's right hand.
Well, in the Naruto universe, the Shinigami is a very mysterious and powerful entity. In this 'Left Hand of the Shinigami' fanfiction, it could be that Naruto discovers something about the Shinigami's left hand that no one else has. Maybe it has a hidden seal or a power that can be harnessed. It could also lead to a new arc in Naruto's life where he has to deal with the consequences of this discovery, like facing new enemies who are also interested in this power. And he might have to figure out how to control this newfound connection to the Shinigami's left hand.
Since it's a Naruto - based fanfiction, Naruto is definitely a main character. In addition, it could feature the Hokages, as they often play important roles in Naruto's life and they might be involved in the mystery of the Shinigami's left hand. Also, villains from the Naruto series could show up. For example, Orochimaru might be interested in this power of the Shinigami's left hand and try to take it from Naruto, making him a major character in this fanfiction as well.
The plot might involve a new character who is bestowed with the 'Right Hand of God' power. This character could initially struggle with this power as it's so overwhelming. They might be hunted by those who want to take the power for themselves. Along the way, they team up with Naruto and his friends to protect the power and use it for good in the shinobi world.
Well, in some fanfictions, the Shinigami might save Naruto by using its special powers to reverse a fatal curse or injury. For example, it could extract a harmful entity that was about to kill Naruto from his body.
Maybe the Shinigami uses its special powers to heal Naruto's severe injuries. For example, it could transfer some of its own spiritual energy to Naruto to revive his fading life force.
It's a bit of a stretch to call Naruto a Shinigami fanfiction. Naruto has a deep - rooted Japanese cultural influence in terms of its ninja theme, which is quite different from the core concept of Shinigami. However, if we look at some aspects like the idea of a character having some form of power over life and death, there could be a very loose comparison. But overall, Naruto stands on its own as an independent and well - developed story that has been carefully crafted by its creator, not a derivative work based on Shinigami.
One possible story could be about a young ninja who is chosen to be Naruto's right - hand when he becomes Hokage. This ninja might have to learn from Naruto's leadership style and face various challenges together with him, like dealing with new threats to the village.
