The Naruto world has a rich lore with tailed beasts and different bloodlines. The Devil May Cry world has its own lore regarding demons and the underworld. In fanfictions that combine these two, the merging of these lores can result in really unique storylines. For example, a fanfiction could explore what would happen if a tailed beast was possessed by a powerful demon from the Devil May Cry world, and how the characters from both universes would deal with such a situation.
Naruto's ability to create shadow clones would be very useful. He could send clones to scout out areas full of demons, or use them as distractions in battle. His rasengan could be a powerful close - range attack against demons. Also, his chakra control could potentially be used to enhance Devil May Cry weapons, like making a sword cut through tougher demon hides more easily.
Naruto himself is often a very popular character in these fanfictions. Since it's a Naruto - based concept with elements of Devil May Cry, he is usually the main focus. Writers like to explore how he would adapt to new powers or new situations.
A Naruto May Cry fanfiction might involve Naruto getting a Devil Arm similar to those in Devil May Cry. This arm could have unique powers that he has to learn to control. It could be a source of both great power and internal struggle for him as he tries not to let the power corrupt him while using it to protect his village and friends.
Another reason might be that they faced some sort of writer's block. Coming up with new plot ideas, especially for a crossover as complex as Naruto and Devil May Cry, can be really challenging. They might have hit a point where they didn't know how to progress the story further. Or perhaps they received some negative feedback early on that discouraged them from continuing.
One great Naruto Kushina Devil May Cry fanfiction could be about Kushina having some sort of connection to the Devil May Cry world. Maybe she has a hidden power that is similar to the devil arms in Devil May Cry. For example, her chakra chains could be related to a special weapon in the Devil May Cry universe.
Yamato's wood - style jutsu could be seen as a form of nature - based magic in the Devil May Cry world. He could use it to create barriers against demons or even trap them, much like how Dante uses his devil arms to fight. His ability to sense chakra might also translate to sensing demonic energy, allowing him to detect hidden demons.
Another option is a new character created specifically for this fanfiction. This character could be a hybrid of a ninja and a demon. They would have an in - depth understanding of both cultures and be the perfect person to run the 'Naruto Devil May Cry Shop'. They could use their dual nature to source and sell items that are relevant to both worlds, and also act as a bridge between the two different groups of characters.
The power - up trope is also popular. In these fanfictions, a character from either universe might gain new powers from the other. For instance, Naruto could gain some devilish abilities from Devil May Cry, like enhanced speed and strength similar to Dante's. This not only makes the character more powerful but also changes the dynamics of the story as they have to learn to control these new powers and how it affects their relationships with other characters.
First, you need to know the characters well from all three universes. Naruto is a determined ninja with a big heart, Dante is a cool and cocky devil hunter, and the characters in Highschool DxD have their own unique supernatural abilities. Then, think of a good plot. It could be a simple story like they all team up to fight a powerful enemy that threatens all their worlds. Or it could be more complex, like a mystery that involves the different power systems of each universe.
