Well, it could sell ninja weapons with a Devil May Cry style twist. For example, kunai knives that have a demonic glow or are made with special materials from the Devil May Cry universe. Maybe there could also be jutsu scrolls that teach techniques inspired by Devil May Cry's combat moves.
In a 'Naruto Devil May Cry Shop' in fanfiction, it might sell items like chakra - enhanced Devil Arms. These could be weapons that can be wielded by both ninjas and Devil May Cry characters. Also, there could be potions that restore both health and chakra at the same time, which would be a really useful item for characters in this crossover setting.
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 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.
One possible plot is that there's a powerful demon in the Naruto universe that has a connection to the underworld of Devil May Cry. Naruto and his friends seek help from Dante and Vergil. Along the way, Naruto learns about the different types of demons in the Devil May Cry world and how to combat them using his chakra in new ways. The story could be filled with intense battles and character development as they all try to stop the demon's evil plan.
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.
Well, one possible plot could be that in a strange crossover world, Naruto's chakra somehow connects with the demonic energy in the Devil May Cry universe. Lady and Trish, being the powerful demon hunters they are, initially see Naruto as a threat. But as they get to know him, they realize his noble intentions. Maybe Naruto helps them in a fight against a powerful new demon that is immune to their usual weapons and tactics. His unique abilities could be the key to victory, and during this adventure, a deep bond forms between them, not exactly a'mate' in the romantic sense at first, but more like comrades. As time passes, this bond could potentially develop into something more, with Naruto learning about their world and they learning about his ninja way.
Well, it could have been about a character from Naruto ending up in the Devil May Cry universe. Maybe Naruto himself gets transported there and has to use his ninja skills to fight demons. He might learn new abilities from the Devil May Cry characters, like Dante's swordsmanship or Vergil's cool moves. And perhaps there would be some sort of conflict between the ninja way and the demon - hunting way of the Devil May Cry world.
One of the main themes is definitely the crossover of abilities. You'll often see Naruto characters using Devil May Cry weapons or Devil May Cry characters using chakra. Also, friendship across universes is a big one. Imagine Dante becoming friends with Naruto and they team up to fight a common enemy. It's all about bringing two different fanbases together through shared story elements.
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.
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.
