Another good one is 'The OC in Sesshomaru's World'. Here, the OC is from a different dimension and her presence disrupts Sesshomaru's normal life in an unexpected way. The fanfiction delves deep into Sesshomaru's character and how he copes with this new addition to his world.
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.
I really like 'Sesshomaru's Unlikely Companion'. In this fanfiction, the OC has a unique power that draws Sesshomaru's attention. It's full of action and the slow - burn romance between them is well - written. There are also some great descriptions of the Inuyasha universe.
There's also 'Fem Inuyasha's Adventure'. This one is interesting because it focuses on fem Inuyasha's journey alone at first, and then Sesshomaru enters the story later. It shows her growth as a character and how their relationship evolves in a somewhat unexpected way.
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.
You can start by looking on fanfiction websites like Archive of Our Own (AO3) or FanFiction.net. AO3 often has a great variety of Inuyasha Sesshomaru OC fanfictions with different themes and writing styles. FanFiction.net also has a large collection, though the quality may vary more. Another option is to join Inuyasha - related forums or groups on social media platforms, where fans might share their favorite OC fanfictions or even write their own and post links there.
Characterization is key in a great Inuyasha Sesshomaru OC fanfiction. The writer needs to capture the essence of Sesshomaru and Inuyasha accurately. Sesshomaru should still be his aloof, powerful self, and Inuyasha his hot - headed but good - hearted character. The OC should interact with them in a believable way. Moreover, the writing style matters. A vivid and engaging writing style that can bring the feudal Japan setting of Inuyasha to life is a big plus. Good use of description, whether it's about the landscapes or the characters' emotions, can make the fanfiction stand out.
Another great one is 'Fate's Intertwining'. This fanfiction focuses on how their destinies are linked in ways they don't initially understand. It has a lot of emotional depth and some beautifully written scenes between Sesshomaru and Fem Inuyasha.
One idea could be to give the sister a unique power. For example, she could have the ability to control the elements, which would set her apart from Sesshomaru and Inuyasha. This power could also create interesting storylines as she might have to learn to control it.
You can also build a plot around her relationship with Sesshomaru. Maybe there is a rift between them that needs to be healed. She tries to do something to regain his trust or respect, but things keep going wrong. This internal family drama can be intertwined with external threats like demon battles.
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.
I really liked 'The Moonlit Mate'. In this fanfiction, the OC is a powerful healer who catches Sesshomaru's attention. The story is filled with adventure as they face various challenges together. It also delves deep into Sesshomaru's character, showing how he gradually opens up to the OC. And there's 'Destined Encounter' where the OC has a mysterious past which ties in with Sesshomaru's own journey. The writing is engaging and the relationship between the two characters feels very natural.
