One common theme is friendship. They start off as strangers or even with some animosity, but over the course of the story, they become friends. For example, in many fics, they realize they have more in common than they thought.
Well, obviously Nero and Sparda are the main characters. Nero, with his white hair and his Devil Bringer arm, is a key figure in the Devil May Cry series. He's known for his brashness and his strong sense of justice. Sparda, on the other hand, is a legendary demon. He's the father of Dante and Vergil. He's a very powerful and mysterious character. In this fanfiction, their encounter would be the central focus, and their different personalities and powers would drive the story forward.
Perhaps Nero meets Sparda in a dream - like realm. Sparda appears as a sort of spirit guide. He shows Nero visions of the past, including his battles against powerful demons to protect the human world. Nero, inspired by these visions, tries to incorporate Sparda's fearless and strategic approach in his own battles. In the real world, Nero starts to notice a strange connection between his powers and some of the relics left behind by Sparda, and he embarks on a quest to uncover the secrets of this connection.

Give the Okami in human form a backstory that ties them to their original form. Maybe they were cursed to be in human form as a punishment or they chose to take human form to better understand humans. Their actions should also be influenced by their Okami nature.

Their speech could also be a bit more formal or archaic, reflecting their otherworldly origin.
Well, in some fanfictions, Asta's demon form might have a different appearance. Instead of the typical spiky look, it could be more streamlined and elegant, with a black and red color scheme that gives off an even more menacing vibe. Also, his demon form could possess the power to create illusions, which he uses to deceive his enemies. This would make him a more versatile fighter and add a new dimension to his battles.
