The Akatsuki members might also play a role. Since Naruto's past could be related to the larger shinobi world, the Akatsuki, with their various motives and powers, could be involved. For example, if Naruto's family had something to do with a powerful tailed beast that the Akatsuki is after, it would draw them into the story and make them important characters in this fanfiction.
Perhaps in the fanfiction, Naruto's past catches up when he discovers that he has a long - lost relative who has a unique power. This relative might be on a different path, either good or bad, and Naruto has to figure out how to deal with this newfound family connection. It could involve a lot of emotional turmoil as he tries to understand his place in this new family dynamic.
Obviously, Naruto himself is a crucial character. His experiences and growth form the backbone of the story.
Obviously, Naruto is one of the main characters. Since it's about him in the past, he is central to the story. His friends like Sasuke and Sakura might also be involved in some way. And of course, characters from the past like the Sannin (Jiraiya, Tsunade, and Orochimaru) could play important roles as they are key figures in Naruto's world history.
Sasuke also plays a crucial role. His relationship with Naruto, whether it's one of friendship or rivalry in the end of the fanfiction, can shape the overall story. He has his own journey of redemption or further descent into darkness, depending on the plot.
Well, Naruto himself is of course a very important character. Since it's about him being blessed by the gods, he's at the center of the story. The gods who bless him are also important characters, although they might be more of a mysterious and powerful presence. And his friends like Sasuke and Sakura are likely to be important too. They would probably react to Naruto's new powers and the changes in his life. Sasuke might be a bit jealous at first or curious about how to get similar powers, while Sakura would be concerned about Naruto's well - being.
Obviously Naruto and Kushina are the most important. But Minato, Naruto's father, also plays a big role as he is part of the family. Also, characters like Jiraiya, who was Minato's teacher and had an influence on Naruto as well, could be important in the fanfiction.
In this fanfiction, Naruto is central. But the Kyuubi itself is also a key character in a way. The way it interacts with Naruto during the revelation and how it affects Naruto's actions is crucial. Other characters like Jiraiya might also be important. Jiraiya could have some knowledge about the Kyuubi that he shares with Naruto to help him better understand and control this new - found power. And of course, the enemies that Naruto faces after the revelation would also be important characters in the story.
Obviously Naruto and Kaguya are the most important. Naruto as the one to free Kaguya, and Kaguya as the one being freed.
Obviously Naruto is a crucial character as he is the host of the Kyuubi. His family members like his father, Minato, and his mother, Kushina, are also important. Minato was the Fourth Hokage and had a role in sealing the Kyuubi within Naruto. Kushina was the previous Jinchuriki of the Kyuubi.
Obviously, Ino is a very important character. Her father, Yamanaka Inoichi, is also crucial as he has a lot of influence on Ino and their family. Ino's mother, although not as much in the spotlight, can play an important role in family dynamics. And then there are Ino's friends like Sakura who could interact with her family and be part of the story in some way.
