One common theme is the clash of different power systems. Naruto has his chakra - based ninja abilities and Nioh has its own unique combat mechanics like ki and yokai powers. Fanfictions often explore how these two different power systems interact when the characters from both universes meet. Another theme is the exploration of new worlds. Naruto coming into the Nioh world or vice versa allows for a lot of world - building and discovery within the fanfic.
One great Naruto x Nioh fanfiction is 'Naruto in the World of Nioh'. It has an interesting plot where Naruto is somehow transported to the Nioh universe. He uses his ninja skills in the new and dangerous world filled with yokai. Another one could be 'Nioh's Influence on Naruto'. This fanfic explores how the mechanics and lore of Nioh might change Naruto's abilities and his way of thinking.
One interesting Naruto Nioh fanfiction could be about Naruto being transported into the world of Nioh. He might use his ninja skills in the dark and dangerous world filled with yokai. For example, his shadow clone jutsu could be used in creative ways to fight off hordes of enemies.
You can try websites like Fanfiction.net. It has a large collection of fan - made stories, and you can simply search for 'Naruto Nioh' in the search bar. There are likely to be many different takes on the crossover there.
One reason is the unique gameplay of Nioh. The intense combat and the way the game presents its challenges inspire fanfiction writers. For example, they can write about how a character overcomes a particularly difficult boss in a different way. Also, the characters in the game have a certain charm. Writers can develop their relationships further in fanfiction, or even create new characters that fit into the game's universe. The game's setting also plays a role. The dark and moody atmosphere of feudal Japan in the game is a great backdrop for all kinds of stories.
Some might like a Nioh crossover with anime universes. For instance, a crossover with Naruto. The ninjas in Naruto could meet the samurai from Nioh. They could have battles or even learn from each other's fighting styles. It would be really exciting to see how the jutsus in Naruto compare to the combat skills in Nioh.
