Most likely Naruto would be one of the main characters since it's in the title. And probably some of the well - known characters from the DxD world like Issei Hyoudou would also be important. They might interact in various ways, like Naruto could be a rival or an ally to Issei.
It's also possible that some minor characters from either universe could become more important in this fanfiction. Maybe a side character from Naruto who was overlooked in the original series gets a chance to shine in the DxD world. Or a less - known devil in DxD becomes a key figure in Naruto's new adventure. The fanfiction author has the freedom to reimagine and elevate the roles of various characters to create a unique and engaging story.
Since it's a fanfiction, it could be a very creative take on combining these two universes. It could explore how Naruto's values and personality would interact with the often more complex and morally ambiguous world of DxD. He might bring his sense of justice and friendship to a world full of power struggles and different factions. It could also be about Naruto getting a chance to correct some mistakes he made in his own world, but in the context of the DxD world, which would add a whole new layer of challenges and opportunities.
Naruto is likely to still be one of the main characters. His journey and growth are central to the Naruto universe. Sasuke would probably also be a main character as his relationship with Naruto is so important. Sakura might also be there, as she was an important part of the original team. And Kakashi could be a main character as well, being their sensei.
Perhaps there is a group of friends. One of them might be the central character who is given this second chance, and the others play important roles in either helping or hindering this new opportunity. For example, one friend could be really supportive, while another might be jealous and try to undermine the main character's efforts.
Often, in a 'another chance at life fanfic', the main character might be someone who has a lot of regrets. For instance, it could be an old man who looks back on his life and wishes he could change things. When he gets this second chance, he becomes the focus of the story. There could also be supporting characters, like his family members or friends from his previous life who are affected by his new - found opportunity.
Since I haven't read the novel, I can't say for sure who the main characters are.
Well, aside from Naruto and Issei, there could be other important characters. Rias Gremory, who is a devil princess in DxD, might play a significant role. She could be curious about Naruto and his powers, or she might even see him as a potential ally or threat. Also, characters like Akeno Himejima, Kiba Yuuto, and others from the DxD series could be part of the story and interact with the reborn Naruto in different ways.
Naruto is the key character in 'Naruto Chance to Change Fanfiction'. However, other main characters could be the Hokage at the time, like Tsunade. Her leadership and the decisions she makes in the village would be affected by Naruto's changes. Also, characters like Shikamaru, who is one of Naruto's friends and a strategic thinker in the village, would be important as he would be involved in any new plans or changes Naruto brings about.
The Hokage, whether it's Tsunade or others, would also be main characters. Since Naruto's actions often have a big impact on the village leadership and vice versa. With a second chance, Naruto's interactions with the Hokage could lead to different policies and decisions for the Hidden Leaf Village, making the Hokage an important part of the story.
Naruto is definitely a main character. His presence and his god - like abilities are what make this fanfiction unique. Then, there could be characters like Rias Gremory. She's an important figure in the DxD world, and her relationship with Naruto could range from being an ally to a potential love interest. Also, characters like Akeno Himejima could be involved. She might be curious about Naruto's powers and his different way of doing things compared to the DxD characters.
Obviously, Naruto is one of the main characters. And then there's his new brother. Depending on the fanfiction, there might also be other well - known Naruto characters like Sasuke or Sakura. They could be involved in the story in different ways, like being friends or foes to the new brother.
