Well, in 'naruto god of shinobi fanfiction', it often explores Naruto attaining a god - like status within the Naruto universe. It could involve him having extraordinary powers, perhaps being able to control all the elements in a way far beyond what was shown in the original series, and having an almost omnipotent influence over the shinobi world.
Often, in Naruto fanfiction, Naruto himself could be depicted as the 'god of shinobi' in some alternate universe scenarios. Since he has the Nine - Tails' power and has achieved great feats in the original series, it's not a stretch for some fanfiction writers to take his powers to a god - like level.
Typically, the 'god of shinobi' in Naruto fanfiction would have extremely powerful chakra. This could be chakra on a scale that far surpasses even the most powerful shinobi in the original Naruto series, like Hashirama Senju or Madara Uchiha.
In this fanfiction, it may start with Naruto already on a path to becoming the next god of shinobi. He could be training in a secluded place, away from his friends and village. As he progresses, he might encounter strange and powerful creatures or beings that test his resolve and power. His journey could also be about uniting the different shinobi clans under his leadership as the new 'god'. This would require him to not only show his physical and jutsu - based strength, but also his wisdom and ability to bring peace. He might also have to make sacrifices along the way, like giving up some of his personal relationships or his own desires for the greater good of the shinobi world.
It could be about Naruto achieving a god - like status among shinobi. Maybe it details his super - powered feats, new jutsus he develops that are almost divine, or how he overcomes impossible odds and is revered as a god by the shinobi world.
Obviously, Naruto would be the main character as it's about him being the 'god of shinobi'. But there could also be other characters like Sasuke, who might be in a different relationship with Naruto now that he is a god - like figure. Sakura could also play a role, perhaps as a healer trying to understand Naruto's new powers.
In a 'naruto god of shinobi fanfic', it may tell the story of Naruto becoming a god - like figure in the shinobi universe. This could include him gaining divine powers such as immortality or the ability to see the future. The fanfic might also show how Naruto uses these powers to bring peace to the shinobi world. He could use his new powers to end all wars and conflicts, and to create a new era where all shinobi live in harmony. However, it might also explore the challenges that come with such great power, like the temptation to abuse it or the isolation that might come from being so much more powerful than everyone else.
One interesting concept could be new and unique jutsu created by the god - level shinobi. For example, a jutsu that manipulates time in a different way than the existing ones in the Naruto universe. Another concept might be the relationships between these super - powerful shinobi and the normal characters. They could act as mentors, or their presence could change the power dynamics in the Hidden Villages.
One common theme is friendship and alliances. Naruto is known for making friends and in the DxD fanfiction, he might form new alliances with characters from DxD. Also, the theme of self - discovery. As Naruto enters a new world, he has to learn about himself in this different context. For example, how his ninja way might change or stay the same. And of course, there's often the theme of combat. Since both series have a lot of action, seeing Naruto fight in the DxD world against different opponents is a big draw for these fanfictions.
Obviously Naruto would be one of the main characters. Since it's about him becoming the next god of shinobi. There might also be Sasuke, as he has always been an important part of Naruto's story. And perhaps some of the older characters like Kakashi could also play important roles, guiding Naruto in his journey.
Most likely Naruto would be the main character since it's in his name. But there could also be other characters like Sasuke, Sakura, Kakashi etc. as they are important in the Naruto universe and might interact with Naruto in his 'god among shinobi' state.
