Well, the main characters might be divided into two main groups. On one side, we have the well - known and respected ninja families in the Leaf Village. On the other side, the Agents Mist could be made up of characters with unique abilities and backgrounds. There could be a female ninja from the Leaf Village who is curious about the Agents Mist and tries to learn more about them. And within the Agents Mist, there could be a character who has a personal vendetta against the enemy the Leaf Village is facing, which drives his actions during the war.
The main characters could include the Hokage of the Leaf Village, who has to make the tough decisions regarding the war. Among the Agents Mist, there might be a mysterious figure who holds the key to their special powers. There could also be a group of young ninjas from the Leaf Village who are initially skeptical of the Agents Mist but later come to respect and rely on them. For example, a ninja with a strong sense of justice might be one of the main characters, constantly challenging the Agents Mist to prove their good intentions.
Most likely, there would be the leaders of the Leaf Village. And of course, the members of the Agents Mist. Maybe there's a young, brave ninja from the Leaf Village who befriends a member of the Agents Mist, and they become the central characters.
Well, it could be about the Leaf Village facing a powerful enemy and the 'Agents Mist' playing a crucial role. Maybe they have some special powers or skills that turn the tide of the war. They might be a new group in the Leaf Village that was previously unknown, and now they are the village's last hope.
Obviously, Naruto would be one of the main characters as he is from the Leaf Village and would likely lead the charge against the agents of Mist. Sasuke could also be there, as he often teams up with Naruto in important battles. Sakura might be involved too, using her medical and combat skills. And from the Mist side, there could be some important ninja agents who are the antagonists, though their identities would be developed as the story progresses.
Well, in this fanfiction, perhaps the 'agents mist' are actually a secret group within the Mist Village that has been causing trouble. So, the Leaf decides to go to war to stop them. The story could involve Naruto learning about the motives of these agents and trying to find a diplomatic solution while also being prepared for combat. There might be some betrayals and unexpected alliances along the way. For example, some members of the Mist Village might side with the Leaf against the agents. And Naruto's friends from the Leaf, like Sasuke and Sakura, would play important roles in the battles and the diplomatic efforts.
Haku is also very popular. His loyalty to Zabuza and his gentle yet powerful nature are appealing aspects. Fanfictions might explore his life in the Hidden Mist Village more, like his training and how he came to be so skilled at using his ice - related jutsu.
I'm not entirely sure, but it could be some of the survivors from the original 'the mist' story. They might have different personalities and skills that are further explored in the fanfiction.
Since it's 'the lion goes to war story', the main character is most likely the lion itself.
Since the title only mentions Sakura, she's likely to be one of the main characters. But there could be others, like the prison guards or fellow inmates. Maybe there's a character who befriends Sakura or an antagonist who makes her life difficult in the prison.
Kakashi could also be a main character in certain 'naruto red mist fanfiction'. His experience and knowledge could be important in figuring out the mystery of the Red Mist. He might be mentoring the younger characters on how to handle the new threats and challenges that the Red Mist brings.
Obviously, Sakura is one of the main characters. In many such fanfictions, there could also be characters like Naruto and Sasuke who interact with Sakura in different ways due to her being from the Hidden Mist. Maybe Kakashi could also be involved to mentor or guide her.
Definitely Naruto. His whole life was full of suffering because of the Leaf Village's treatment of him as a jinchuriki. Sakura could also be involved. In some fanfictions, her growth might be stunted by the village's lack of proper support or opportunities for female ninjas. And Kakashi. His past traumas related to the village, like the loss of his teammates, could be used as a way to criticize the village's way of handling missions and the safety of its ninjas.
