The two main characters are Naruto and Rias. Naruto, with his ninja skills and his journey of growth in his original story. Rias, whose actions towards Naruto are the central focus of this fanfiction. There could be side characters like Naruto's friends from his world who might try to find out what happened to him, or characters related to Rias who could either support or oppose her decision to leave Naruto to die.
Well, perhaps Rias, for some reason, abandons Naruto in a dangerous situation where he is left to die. Maybe there's a conflict of interests or a misunderstanding between them. It could be that Rias has to make a tough choice that unfortunately leaves Naruto in a life - threatening state.
Obviously, Naruto would be one of the main characters. Depending on the specific plot, Sasuke could also be involved. He might be one of the ones who either helps Naruto or is part of the reason Naruto is left to die. Sakura could also play a role, maybe she has a change of heart towards Naruto in the fanfic.
Naruto and Rias are the central characters. Naruto is known for his never - give - up attitude and his array of ninja techniques. Rias is a complex character with her own political and social standing in the devil world. However, in some fanfictions, other characters from both the Naruto and High School DxD universes can become important. Kiba from Naruto might befriend Naruto in the new world and help him understand the devil society better. And from the High School DxD side, Akeno, Rias' friend, could play a role in either supporting or testing Naruto's relationship with Rias.
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.
The main characters are Naruto and Rias. Naruto is known for his rasengan and his ability to make friends and inspire those around him. Rias, on the other hand, is a leader among devils and has a group of loyal servants. In this fanfiction, with Rias being pregnant, their relationship and how they handle this new situation become the central focus of the story.
Danzo could be the main villain. He is known for his underhanded tactics and his dislike for Naruto. He might see Naruto as a threat to his power and plan to get rid of him by leaving him in the Forest of Death. Danzo could have manipulated some other characters to make it seem like it was a legitimate mission gone wrong.
Well, Naruto is the key character as the title implies. However, in fanfictions, authors often introduce new characters as well. There could be a new villain who is constantly trying to kill Naruto but fails every time. And of course, Naruto's friends like Sakura, Kakashi, and Shikamaru might also be main characters. They could be involved in protecting Naruto or helping him out of those life - threatening situations. For example, Sakura might use her medical skills to heal Naruto when he's on the verge of death, and Kakashi could use his wisdom to guide Naruto to avoid death - traps.
The main characters are Naruto and Rias. Naruto is the godlike character. His role is often to be the overpowered force that challenges or opposes Rias. He might use his incredible powers to put Rias in difficult situations. Rias, on the other hand, is the character who is often on the receiving end of Naruto's actions. She may be portrayed as an antagonist or at least someone who has to deal with Naruto's godlike presence.
Issei could be involved. He might be initially skeptical of Naruto, but as they train together or fight side by side, they become friends. Akeno could also play a part. She might be curious about Naruto's powers and try to learn some of his techniques. Kiba would be another character. Since he has his own combat abilities, he and Naruto could have friendly competitions to see who is stronger in different aspects.
Kakashi could also be involved. Maybe he's put in a difficult position where he can't save Naruto for some reason, like being under a powerful genjutsu or being blackmailed. This would create an interesting conflict as he's Naruto's teacher and mentor.
