It's also possible that Kushina, Naruto's mother, could play a significant role even if she's not alive in the main Naruto storyline. The fanfic could explore her love for Naruto in a different way, perhaps through flashbacks or some sort of spiritual connection. And of course, characters like Iruka Sensei or Jiraiya could be involved as they have also shown parental - like affection towards Naruto in different ways.
I don't know for sure as I haven't read it. But it could be the mother, of course, and the 'knight' character. There might also be other Naruto characters like Naruto himself, Sasuke, or Sakura if the story is set in the main Naruto timeline and intersects with the main characters' storylines.
Obviously, Hinata's mother would be one of the main characters. Hinata's father would likely be another important character as their relationship is crucial to Hinata's family background. Also, young Hinata herself could be a main character in flashback scenes, showing how her mother influenced her in her formative years.
I don't know for sure, but it could be the mother herself, her children, and perhaps some of the well - known Naruto characters like Naruto, Sasuke, or Sakura who might be involved in the story related to the mother's sins.
Maybe it could be an existing female character from the Naruto series who steps into a motherly role for Naruto. For instance, Tsunade. She already has a sort of protective and guiding role in Naruto's life, and in the fanfiction, this could be developed further into a full - fledged motherly relationship.
It could be Naruto and Hinata. Their relationship in the original series had a lot of potential for further exploration in a love - story - centered fanfic. Hinata has always had deep feelings for Naruto, and a fanfic could really expand on how their relationship developed into a full - blown love story.
Well, of course, the mother is a central character. She could be a strong - willed woman who has to face many difficulties in life while still showing great love for her child. For instance, she might be a single mother who has to work multiple jobs to support her family but still finds time to be there for her child's school events.
I think Tsunade could be a main character in a 'naruto himekishi fanfic'. Given her strength and leadership, she could be in charge of the himekishi in the Hidden Leaf Village. Another possible main character could be Rock Lee. His hard - working and determined nature would fit well with the concept of the himekishi. And of course, Sasuke could also be involved. Maybe he has a complex relationship with the himekishi, either as an ally or an antagonist depending on the story's direction.
Obviously, Naruto could be one of the main characters. He could be either a patient or someone helping out at the hospital. Another main character could be Sakura. Since she has medical skills, she could be a doctor or a medic - ninja in charge at the hospital. And then there could be a new character, like a young orphan who is being trained as a medic - ninja at the hospital and has an interesting backstory.
In a 'Naruto of the Sand' fanfic, the main characters could be Kankuro. He has his own unique puppet - using abilities and his relationship with his siblings and the Sand Village could be explored. Another main character could be the Kazekage at the time of the fanfic's setting. Their leadership and decisions would impact the story greatly. Also, Shukaku could be a main character in a sense. Since it is related to Gaara and has a powerful presence, its influence on the events in the Sand Village could be an interesting aspect to write about.
Obviously Naruto himself could be a main character. His determination and never - give - up attitude would be key in facing the Eldrazi threat. Sasuke could also be a main character, his powerful Sharingan and combat skills would be useful in battles against the Eldrazi.
