One idea could be a 'what if' scenario. For example, what if Yusuke had accepted Raizen's offer to become a full - fledged demon right away. Another idea is to focus on the relationships between the characters in a different way, like a deeper exploration of Kuwabara and Yukina's relationship that was only hinted at in the original. You could also do a time - travel fanfic where a character goes back in time to change a key event in the Yu Yu Hakusho story.
One common theme is unrequited love. Often, a character might have feelings for another that are not initially reciprocated, creating a lot of tension and drama. For example, a character could be secretly in love with their rival.
The main difference is the gaming element. In 'yu yu hakusho gamer fanfiction', there are often references to game mechanics like leveling up, stats, and skills. Regular Yu Yu Hakusho fanfiction usually focuses more on the original story elements and character relationships without these gaming aspects.
In general, it is legal to engage with Yu Yu Hakusho fanfiction. Fanfiction exists within a legal gray area in some ways, but as long as it adheres to certain principles. The fanfiction should be non - commercial (in most cases), and not be using the characters in a way that defames or misrepresents the original work too severely. Reading fanfiction on common platforms is a common and legal practice, as long as the platforms also follow the appropriate laws regarding intellectual property.
There is a bit of a love story in Yu Yu Hakusho. It's not the main driving force of the show, but it does contribute to the character development and adds some emotional complexity to the narrative.
The Miyuki x Yusuke relationship in Yu Yu Hakusho fanfics often delves into the uncharted territories of the story. Fanfic writers might take liberties with their relationship to show how they could grow together. It could be a slow - burn relationship where they start as acquaintances and gradually develop deeper feelings. Or it could be a more instant connection based on a shared goal or a life - changing event that brings them closer.
Another theme is often the outsider status. Since the character is an original creation (OC), they are likely to be an outsider in the established 'Yu Yu Hakusho' world. This can lead to themes of acceptance or rejection. They may struggle to fit in among the demons, spirit detectives, and other beings in the story. Also, there can be themes related to the witch's origin. Maybe they come from a different dimension or a hidden coven within the 'Yu Yu Hakusho' world, and exploring this origin can be a major part of the story.
