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.
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.
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.
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.
The plot could involve Naruto coming back to the Leaf Village to fulfill a prophecy. He may have discovered something during his travels that made him realize he has a crucial role to play in the village's future. Along the way, he could face challenges from within the village, like some people being skeptical of his newfound knowledge or power. But through his determination and the bonds he has with his friends, he overcomes these obstacles and helps the village thrive.
In one possibility, Naruto might leave the Leaf due to a misunderstanding. For example, if the villagers continue to show distrust towards him despite his efforts. He could set out on a journey to find a place where he truly belongs. Maybe he meets some new allies on his way, people who understand him without any prejudice.
Well, it could be about Marco using his unique skills and experiences from his regular adventures to face the challenges of war. Maybe he has to lead a group of soldiers, or he's on a special mission behind enemy lines.
Well, it could be about Jon Snow leading his men into a great battle against the White Walkers. Maybe he discovers new strategies or forms unexpected alliances during the war.
Maybe it's to protect the village. He could discover a threat that he can only face away from the Leaf Village, to keep the danger from directly reaching his home and loved ones. He leaves as a form of self - sacrifice.
Perhaps Harry goes to Forks because he senses some dark magic there that is related to the Volturi. He could end up getting involved in their power struggles. He might also start to learn about the unique rules and powers in the Forks supernatural world and compare them to what he knows from the wizarding world. For example, the way vampires have their own kind of 'magic' with their super strength and speed.
One possible plot could be Naruto struggling to adapt to the magical world. He might try to use his ninja skills in Hogwarts, which could lead to some hilarious situations. For example, he might attempt to run up the walls using chakra in a magic - filled corridor and startle the other students. Also, his strong sense of justice would likely make him stand up against any dark magic threats in Hogwarts, just like he did in his own world.
