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.
First, decide on the crossover universe. Whether it's another game, an anime, or a historical setting. Then, research both Nioh and the other universe. Know the characters, the lore, and the rules of each. After that, come up with a basic plot. For example, if it's a Nioh and Final Fantasy crossover, you could have a plot where the crystal in Final Fantasy is somehow related to the Amrita in Nioh. Then start writing your first chapter, introducing the main characters and the initial situation.
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.
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 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.
Well, 'Nioh: A Samurai's Redemption' is a fanfiction worth checking out. It follows a samurai who has fallen from grace in the game's world and his journey to regain his honor. It has some great action scenes that are really in - line with the combat style of the Nioh game. Also, 'Nioh: Shadows of the Past' is good. It explores the history of the various yokai in the game and how they came to be, adding more depth to the game's lore.
