It could be Kakashi. He's very knowledgeable about all kinds of ninja techniques. He might have come across some ancient scrolls or something related to summoning kami and help Naruto figure it out. Another possibility is that an unknown hermit in the fanfiction, who has been secretly observing Naruto and decides to come forward to teach him the secrets of summoning kami because he sees Naruto's potential and the good in him.
Maybe Jiraiya. Since Jiraiya was Naruto's mentor and taught him a lot of things. He might have some knowledge about summoning kami and pass it on to Naruto.
Well, it could make the plot more complex. Naruto's new ability might give him an edge in battles. For example, if he summons kami during a fight with a powerful enemy like Sasuke, it could turn the tide. Kami might have special powers that Naruto can use to his advantage, like some sort of super - healing or powerful attack that was previously unavailable to him.
Maybe it's a completely new and unknown kami. A kami created specifically for this fanfiction. This kami could have unique powers and a different view of the ninja world compared to the existing characters in Naruto. It would add a fresh and exciting element to the story.
Maybe it's an existing character from Naruto who has been elevated to Kami status. For example, Tsunade could be turned into a Kami, and Naruto's relationship with her could be a very different dynamic from their previous ninja - leader relationship. Or it could be Kaguya, who was already a very powerful being, and in this fanfiction, she reforms and becomes a Kami and Naruto's wife.
In fanfiction, the 'kami' could be an original deity created by the author. This new 'kami' could have its own motives and reasons for giving a gift to Naruto. Maybe it's a kami that has been observing Naruto's journey and decides to interfere to help him achieve a greater purpose. It could be a kami associated with nature, like a kami of the wind or the fire, and the gift could be related to that element.
Perhaps it could be a female version of an existing kami from Naruto lore. For instance, a female counterpart of the Sage of Six Paths. She would have vast knowledge and power, and her training of Naruto would be a way to pass on that ancient wisdom and strength.
Since there are countless fanfiction works, especially in the Naruto fandom, it's very difficult to say who the author of 'kami saves naruto fanfiction' might be. It could be an amateur writer who just wanted to explore this unique idea of a kami saving Naruto, or it could be someone more experienced in writing fanfiction, but without further research, we can't be sure.
Many 'kami naruto fanfiction' pieces tend to blend the spiritual elements of Kami with Naruto's more physical and combat - oriented world. They might explore how Kami's existence affects the balance of power in the ninja villages. Also, these fanfictions sometimes create new relationships between Kami and other characters in the Naruto universe, like Kami having a special bond with Kakashi or Sasuke in some stories.
It could be fire - breathing dragons. Given Naruto's own energetic and passionate nature, fire - breathing dragons would be a fitting match. They could add a new level of destructive power to his arsenal.
In some Naruto fanfictions, it's possible for Naruto to summon snakes. Fanfiction often takes creative liberties, so writers might give Naruto this ability for the sake of an interesting plot twist or a new power - up. It allows for different storylines to develop, like Naruto using snake - based jutsus or having a connection to snake - related elements in the Naruto universe that he doesn't have in the original series.
Obviously Naruto is one of the main characters as he is the one being revived. And Kami, who is performing the revival, is also a crucial character. There might also be other characters like Sasuke, Sakura, and Kakashi who could be involved in the story after Naruto's revival. For example, Sasuke might be initially skeptical about Naruto's return or Sakura could be overjoyed and help Naruto get back to his normal self.
