Is there any Naruto fanfiction involving Casull and Jackal?

It could be about a new adventure. Maybe Naruto and his friends encounter Casull and Jackal, who have some special powers or knowledge that can help them in their fight against the villains in the Naruto world.

Well, one idea could be that Naruto is somehow transported to ancient Egypt and gets involved with the Jackal Army. Maybe he uses his ninja skills to help them in a battle against an evil force that threatens both the ninja world and the Egyptian realm.

The unique combination of Naruto's world and the concept of a Jackal. In normal Naruto, there are no Jackals, so in fanfiction, it brings in a new type of character or creature that can change the dynamics of the story. For example, it might have different abilities compared to the regular Naruto characters.

There might be a fanfiction where Naruto is summoned to the devil world by Serafall. In this story, Naruto could be seen as an exotic being, and he has to navigate the complex politics and power struggles in the devil world. Serafall might take Naruto under her wing, teaching him about the devil world while Naruto teaches her about his ninja way. It could be a story full of adventure and cultural exchange between two very different universes.

Yes, there are quite a few. Some focus on her training and growth within the Hidden Leaf Village. They might explore her relationship with her sister Hinata and how she's influenced by the events in the Naruto world.

Yes, there are Naruto fanfictions with magic. Many fans like to add unique elements to the Naruto universe, and magic is one of them. It can create really interesting and different storylines, like Naruto having a new power that is related to magic, or characters from the Naruto world interacting with magical beings.

Yes, there are many Naruto fanfictions that explore the relationship between Naruto and Itachi in appropriate ways. Some might focus on their different ideologies, their potential as allies in different scenarios, or how they could have interacted more deeply in the Naruto universe without straying into inappropriate territory.

Perhaps the Jackal Army is in search of a powerful artifact that was lost long ago. Naruto, with his skills in finding hidden things and his ability to overcome obstacles, joins them on their quest. Along the way, they face many challenges like traps in ancient tombs and battles with other mythical creatures. Naruto uses his shadow clones to solve some of the puzzles and his Rasengan to fight off enemies. The Jackal Army, on the other hand, uses their knowledge of Egyptian magic and their physical strength. As they get closer to the artifact, they realize that there is a greater conspiracy at play that involves a powerful ninja from Naruto's world who wants to use the artifact for his own evil purposes.

Sure. One great Naruto Jackal fanfiction is 'The Jackal's Path in Naruto'. It has an interesting plot where the Jackal character is introduced into the Naruto universe in a very unique way, adding new elements to the existing Naruto storylines.

I'm not sure if there is specific fanfiction directly involving both Naruto and Grayfia from Highschool DxD. Fanfiction can cover a vast range of combinations and crossovers, but this particular one might be quite rare. You could try searching on specialized fanfiction websites to see if any exist.
