In this fanfiction, the story might start with Naruto being found or taken in by the Shinigami. The Shinigami could train Naruto in a different way than the regular ninja training. Naruto could learn secrets about the afterlife which could give him an edge in battles. He may also have a strange connection with the souls, which could be both a strength and a burden. For example, he might be able to communicate with the souls of fallen ninjas and gain their knowledge or power.
The plot could also focus on how Naruto's relationships change. Since he's raised by the Shinigami, he might be an outcast among the normal ninja. His friends might be wary of him at first. However, his new powers and abilities could also attract some who want to use him for their own purposes. Naruto would have to struggle not only with his new identity but also with those who would try to manipulate him because of it.
In a 'Naruto raised by Shinigami' fanfiction, the story could go in many directions. The Shinigami might train Naruto in secret, away from the prying eyes of the Hidden Leaf. Naruto could be taught how to use reaper - like powers, like being able to sever spiritual bonds. This would give him an edge in battles against enemies who rely on normal ninjutsu. Also, his relationship with the Nine - Tails might be affected as the Shinigami has its own connection to powerful entities.
Naruto would probably be more independent in his thinking. Instead of relying on the typical ninja values taught in the village, he'd draw from the Shinigami's teachings. This could make him a bit of a rebel in the eyes of the ninja community. He might question the established norms more often. His development would also be influenced by any special tasks or missions the Shinigami gives him. For instance, if he has to deal with restless souls, it would make him more empathetic towards those in pain, but also more determined to maintain the order between the living and the dead.
The plot might revolve around Harry having to keep his relationship with the shinigami a secret from the wizarding world. As he grows up, he starts to notice how his upbringing by a shinigami gives him an edge in dealing with dark magic. He could use the knowledge of the shinigami to face Voldemort in a way that no one else could, like understanding the true nature of death and using it to his advantage.
He'd probably be more solemn. The Shinigami is a being associated with death, so Naruto would be exposed to serious concepts early on.
Well, it could be really interesting. Harry might grow up with a different set of values. Shinigami are often associated with death in some cultures. So Harry could have a more solemn and perhaps darker view of life. He might be trained in some unique skills related to the Shinigami's nature, like being able to sense death or having some special powers to deal with the afterlife.
One possible plot could be that Naruto grows up with Hanzo's strict and combat - focused training. He might learn unique jutsu and combat strategies from Hanzo early on. This could make Naruto a more battle - hardened ninja at a young age, with a different outlook on the ninja world compared to his canon self.
In this kind of fanfiction, Naruto might grow up with unique abilities and perspectives. Maybe he'd have an instant connection with the bijuu's power and be more in tune with nature. He could also face less discrimination as the bijuu might protect him from the start, leading to a very different Naruto compared to the original story.
One possibility is that Naruto would grow up with a different set of skills. Mei is skilled in water-based jutsu, so Naruto might be more proficient in water techniques rather than wind ones. He could also have a different view on politics and village relations as Mei is from Kirigakure, a village with a complex history.
One possible plot could be that Shisui, with his skills and kind heart, trains Naruto in unique ways. He might teach Naruto advanced stealth techniques early on. Naruto could also inherit Shisui's sense of justice and loyalty, which would shape his character differently from the original series. Shisui could also introduce Naruto to different aspects of Uchiha culture, which would give Naruto an edge in understanding his friends like Sasuke better.
Well, one possibility is that Naruto would grow up with a different view of the ninja world. Nagato's experiences with pain and his radical ideas might influence Naruto. He could be more cynical about the shinobi system at first. But Naruto's own kind heart might also start to change Nagato's views over time, leading to a very different Akatsuki perhaps.
