Naruto would likely be stronger in a direct combat situation. He has been through numerous battles, has a vast array of jutsu at his disposal, and his physical strength and speed are enhanced by his ninja training and the Nine - Tails. Shin Natsume, while having interesting spiritual powers, may not be as well - equipped for a full - on battle. But Shin's powers could be useful in a support role, like helping Naruto detect hidden enemies or sense danger from afar.
One possible plot could be that Shin Natsume, with his unique abilities, somehow gets transported to the Naruto world. He meets Naruto and they initially have a misunderstanding as their worlds are so different. But then they realize they both have a strong sense of justice. Shin could use his powers to help Naruto in a battle against a powerful enemy, like a new Akatsuki member. They learn from each other's determination and courage.
One possible theme could be friendship. Despite their differences, they could learn to appreciate each other and form a bond. Another theme might be the contrast between their personalities. Shin's solemnity against Cayde - 6's levity can create an interesting dynamic throughout the story.
Often, they combine the elements of the Naruto universe, like ninja skills and the idea of friendship within a team, with the yokai - filled world of Natsume Yuujinchou. So you get these really interesting crossovers.
One great Naruto and Maya Natsume fanfiction could be about them teaming up on a mission. Maybe they have to rescue a group of kidnapped villagers. Naruto's strength and Maya Natsume's unique abilities would combine in interesting ways to take on the villains.
Perhaps in a fanfic, Naruto and Maya Natsume are forced to work together in a tournament. They start off not getting along but as they face tougher opponents, they learn to trust and rely on each other. This could lead to a deep friendship or more.
One possible scenario in Tanuma x Natsume fanfiction could be their exploration of a new spiritual mystery together. Tanuma's ability to sense the supernatural to some extent and Natsume's strong connection with youkai would make for an interesting adventure. They might discover a new type of youkai that has a unique power and they have to figure out how to deal with it, whether it's befriending it or finding a way to keep it from causing trouble.
Fanfiction about Matoba and Natsume in Natsume Yuujinchou often explores their complex relationship. It might show how Matoba, with his rather mysterious and sometimes morally ambiguous nature, interacts with Natsume, who is kind - hearted and has the ability to see spirits. Some fanfictions could focus on their potential friendship development, despite their initial differences and the wariness Natsume has towards Matoba due to his methods of dealing with spirits.
Well, in such a fanfiction, they might start by sizing each other up. Shin Malphur is known for his serious and somewhat mysterious nature. Cayde - 6, on the other hand, is more of a joker. So perhaps there would be some initial tension due to their different personalities. Maybe they meet in the middle of a mission. Shin could be all about getting the job done efficiently, while Cayde - 6 might be looking for a more fun - filled approach. This could lead to some interesting banter and a bit of a clash in their methods at first.
It could be the First Hokage, Hashirama. Naruto would be amazed by his powerful Wood - Style jutsu and his ability to create the village. He could learn about the original ideals behind the Hidden Leaf from Hashirama.
