Obviously, Naruto would be one of the main characters. He brings his ninja skills, his strong will, and his unique personality. And from the Rias family, Rias herself would be a main character. She has her own leadership within the family and her devil powers. Also, her peerage members could also be important characters as they interact with Naruto.
Naruto and Rias are bound to be the central characters. Naruto with his determination and power, and Rias with her leadership and magic. But we can't forget about the other members of Rias' peerage. They might have different reactions to Naruto being adopted. Some could be welcoming, while others might be a bit skeptical at first. And Naruto's own comrades from Konoha might also be relevant, perhaps in flashbacks or if they somehow cross over into Rias' world.
Obviously, Harry Potter would be one of the main characters. He brings his own story, skills, and personality from the Harry Potter series. And Rias Gremory would also be a main character as she is from her own universe. Her leadership and unique abilities would play a major role. Hermione and Ron could also potentially be main characters as they are Harry's closest friends. In the Rias Gremory side, her peerage members like Akeno or Koneko might also be important characters in the fanfic.
Obviously Naruto would be one of the main characters as the title implies that he is the one being broken by his family. His family members, whether it's his father Minato, mother Kushina, or other relatives in the Uzumaki clan, would also be main characters as they are the ones causing Naruto's distress.
Well, obviously Naruto himself would be the main character. There could also be his friends like Sasuke and Sakura, who might be involved in the interactions between the two Narutos. Maybe they are confused at first by seeing two Narutos, but then they help them figure out what's going on.
It could still be Naruto himself. Since he's the central character in the original series, many fanfics would likely continue to build on his story.
Cultural clash is also a common theme. Naruto is from a ninja - based culture with its own values like loyalty and hard work. Rias is from a world of demons with a different set of rules. Their interactions often highlight these differences. For example, in some fanfics, Naruto's sense of justice might conflict with the more self - serving nature of some of Rias's allies at first.
Naruto is definitely one of the main characters. He is the key figure in the Naruto universe. His family, which includes Hinata, Boruto, and Himawari, are also likely to be main characters. Boruto, with his own dreams and potential, might be facing some internal or external conflicts. Himawari, being the younger one, could be used to show the family's protective side. And of course, other characters from the original series like Sasuke might also make appearances, as he is Naruto's best friend and they have a deep connection.
Obviously Naruto himself would be a main character. His family members, such as his father Minato and mother Kushina, if they are part of the family issues in the fanfiction, would also be key characters.
Obviously, Naruto himself would be the main character. Since it's about him growing tails, he's at the center of it all. The Nine - Tails would also play a crucial role. It's the source of his tail growth. And his friends like Sasuke and Sakura are likely to be important too. They'll probably be involved in Naruto's journey and how he deals with his new situation.
Most likely Naruto himself. Since it's in the Naruto universe, he's often the central figure. His friends like Sasuke, Sakura, and Kakashi could also be main characters as they usually accompany Naruto on his adventures.
