One great 'Inuyasha Sesshomaru x OC Fanfiction' is 'A Bond Beyond Time'. It has a really interesting plot where the OC is a time - traveler who gets entangled with Sesshomaru's quest. The way the author develops their relationship is quite engaging.
First, you need to understand the characters well. Sesshomaru is a complex character, so study his personality traits from the original series. For the OC, give her a distinct personality and backstory. For example, if she's a healer, explain how she got those skills.
One common theme is the idea of forbidden love. Since Sesshomaru and Inuyasha have a complex relationship in the original series, when Inuyasha is female in these fanfictions, that dynamic of a relationship that goes against the norm is often explored. Another theme could be redemption. Sesshomaru might be on a path of redemption through his relationship with female Inuyasha.
In some fanfictions, Sesshomaru being Inuyasha's father can lead to really interesting plot developments. For example, it can create complex family dynamics. There might be stories where Sesshomaru has to come to terms with his new - found fatherhood and how it changes his relationship with Inuyasha, who he may have previously seen as an enemy or a rival. It also allows for exploring Inuyasha's feelings towards having a father figure like Sesshomaru, who is such a powerful and complex character in the Inuyasha universe.
Sesshomaru would raise the baby with a combination of discipline and protection. He would protect the baby from any threats, using his powerful abilities. At the same time, he would discipline the baby when it made mistakes, teaching it the ways of the demon world. Inuyasha, on the other hand, would add a more carefree and emotional touch to the parenting, creating a balance in the baby's upbringing.
In fanfiction, the baby could be the key to unlocking some long - lost secrets in the Inuyasha universe. Since Sesshomaru and Inuyasha have such complex histories and lineages, the baby might hold the answers to ancient prophecies. It could also have a special bond with the Jewel of Four Souls, perhaps having a unique way of controlling or protecting it that neither of its parents had. And of course, there would be all kinds of emotional drama as the two brothers - turned - co - parents deal with their new relationship.
Sure, there are. A lot of fanfic writers like to experiment with different pairings. In a 'female Inuyasha x Sesshomaru' fanfic, the story could be centered around the power dynamics between them. Since Sesshomaru is a powerful demon and Inuyasha, even as a female, has her own strength. Their relationship could be a complex mix of rivalry and attraction, and the fanfics often play around with these elements.
The theme of coexistence is also quite prevalent. Given their different natures and goals, fanfictions explore how they can live in the same world. Some stories show them finding a balance between their demon and human sides, which is related to their individual identities. It's about how they can tolerate and even support each other in a world that doesn't always accept them for who they are.
A popular one is 'The Meeting of Paths'. This fanfiction focuses on a situation where Inuyasha and Sesshomaru meet under different circumstances than in the original series. It has great characterizations, and the way the two interact and gradually change their views of each other is really well - written.
Yes, there are likely fanfictions out there with such a plot. Fanfiction writers often explore different relationships and scenarios that might not be part of the original canon. They can create unique stories where Rin and Sesshomaru end up getting married, imagining how their relationship could develop over time and what kind of life they would lead together.
