There's no way to tell for sure who the main characters are without more information. It could be original characters created by the fanfiction writer, or it could be based on existing characters from a book, movie, or TV show. For example, it could be two characters from a superhero story who end up becoming fathers.
Obviously Naruto would be one of the main characters since the title has his name. And his father, Minato Namikaze, would also be a central figure as the gift - giver. There might also be other characters like Jiraiya, who was Minato's teacher and could have some connection to the gift or its backstory. Sakura, Sasuke, and Kakashi might also be involved as they are important in Naruto's life and could be affected by the gift in some way, perhaps in their team dynamics or in the battles they face together.
The son would be a younger character, full of new ideas and a bit more rebellious. He might be influenced by new intellectual or social movements of the time. He is in a constant struggle with his father's values and is trying to find his own place in the world.
The main characters are the soldiers who raised the flag on Iwo Jima. Their stories and experiences are central to the novel.
Most likely, the main characters would be the well - known Founding Fathers such as George Washington, Thomas Jefferson, Benjamin Franklin, and Alexander Hamilton. These were key figures in the founding of the United States and would be central to a graphic novel about the Founding Fathers.
Maybe there's an elderly character, perhaps the father's old friend who knew the house in its prime and can share stories about the past. And of course, the mother figure, if she is still part of the family in the context of the novel. She could play a role in the family dynamics within the father's house. There could also be a neighbor who is involved in some way, adding an external perspective to the story of the house.
Typically, the father is often portrayed as more conservative, rooted in the old ways. The son, on the other hand, is more eager for change and new experiences. They interact in ways that highlight their differences and similarities.
I'm not sure as I haven't read the specific story, but it could be the fathers themselves and their children. Maybe there are also other family members like grandfathers or uncles who play important roles in passing on the faith.
The main characters are those soldiers who participated in the Iwo Jima flag - raising. This includes the ones who actually raised the flag, like Ira Hayes, John Bradley, and Rene Gagnon. Each of them had their own story, their own journey to that fateful moment. For instance, Ira Hayes was a Native American who faced discrimination even after his heroic act. John Bradley was a medic. Their individual experiences and how they interacted during the war and after the flag - raising are central to the story.
Since it's based on a true story, the main characters are likely to be the real - life father and daughter involved in that story. There could also be other supporting characters like the mother, siblings, or friends who play important roles in the relationship between the father and daughter. For example, a sister might be a witness to the father - daughter relationship and provide some insights from her perspective.
Gabriel Knight is likely one of the main characters, as his name is in the title.
