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.
Obviously, Naruto would be the main character as it's about him being the 'god of shinobi'.

Sakura could also play a role, perhaps as a healer trying to understand Naruto's new powers.
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.
Obviously, Naruto is one of the main characters as it's about him being a shinobi god. His friends like Sasuke and Sakura are likely to be important as well. They might support Naruto in his new role or have their own story arcs related to Naruto's transformation.
Obviously Naruto would be one of the main characters as the title implies he's the 'god of shinobi'. Sasuke could also be a main character as he has a long - standing relationship with Naruto in the original Naruto story. Sakura might be in it too, since she was part of Team 7 with Naruto and Sasuke.
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.
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.
Obviously Naruto is one of the main characters since it's in the title. He is likely to be the central focus of the story as the last shinobi.
There could be new characters as well. The fanfiction might introduce some young shinobi who are the last hope of the shinobi world. These new characters could have unique abilities and backstories, and they might learn from the older, more experienced shinobi. They could be mentored by the likes of Kakashi or Guy.
The main characters could be a combination of well - known Naruto characters and new ones made for the fanfic. Maybe a Kiri shinobi could be a main character, someone with a unique backstory and abilities. It could also have characters from other villages who come to Kiri for some reason, like a joint mission or to seek refuge. And of course, there might be some antagonist characters within the Kiri village who create conflict for the protagonists.
Naruto himself is often a popular choice in these fanfictions. Since he already has a lot of growth potential in the original series, it's easy to take him to a god - level. Sasuke is also popular as he is Naruto's rival and has his own set of powerful abilities. Another popular character could be Madara Uchiha. Given his already strong powers and complex character, fanfiction writers like to take him to new heights in the god - level shinobi concept.
