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.
Sure, in the world of fanfiction, the possibilities are endless. Since Rin has a special connection with Sesshomaru in the original Inuyasha series, it's not surprising that some fans would write stories where they get married. These fanfictions might explore how Rin grows up and how her relationship with Sesshomaru transitions from a protector - protected dynamic to a romantic and eventually marital one, delving into their emotions and the challenges they might face in such a relationship.
Yes, it is a somewhat popular concept in the Inuyasha fanfiction community. Many fans are intrigued by the idea of Sesshomaru and Rin's relationship evolving into a romantic and marital one. Their unique bond in the original series, where Sesshomaru protects and has a special connection with Rin, makes it an interesting topic for fanfiction writers to explore.
One common theme could be the exploration of their relationship's growth. It might start from Sesshomaru's initial coldness towards Rin and how it gradually thaws as they get closer. Another theme could be the acceptance within the demon world, as Sesshomaru is a powerful demon and Rin is human - or at least was human originally. And there could also be themes of family, as they build a life together and perhaps face issues related to having children or integrating into each other's 'familial' circles.
A frequent theme is the transformation of their relationship. In the original series, it was more of a guardian - ward relationship. In fanfiction about their marriage, it transforms into a romantic and equal partnership. Also, the idea of Rin growing up and becoming a strong character who can stand beside Sesshomaru is a common theme. It shows how she matures and how their relationship evolves over time.
Well, it depends on the specific fanfiction. Some authors might choose to include a kiss between Sesshomaru and Rin as a way to show the development of their relationship. But not all fanfictions will have this. There are many fanfictions that focus more on their platonic bond or other aspects of their characters. For example, some might explore Sesshomaru's growth as a character through his interactions with Rin without getting into a romantic kiss.
One great sesshomaru and rin fanfiction is 'The Bond Beyond Time'. It beautifully explores their relationship as Rin grows up under Sesshomaru's protection. It shows how their bond deepens over the years and the challenges they face together.
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.
Their relationship could start off as a bit rocky. Inuyasha might be a bit impatient with Rin's naivete at first. But as they face challenges together, like fighting off demons or finding their way through a maze - like forest, they start to respect each other. Rin would look up to Inuyasha's strength, and Inuyasha would come to appreciate Rin's kind heart.
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.
For female Inuyasha and Sesshomaru fanfiction, I'd suggest checking out AO3 first. It has a great tagging system that allows you to specifically search for what you want. Also, keep an eye on some dedicated Inuyasha fanfiction review websites. They often feature new and popular stories that involve these characters in different scenarios, which can be really interesting to read.
Another option is Wattpad. Although it's not as specialized in anime - related fanfictions as the other two, you can still find some interesting 'Inuyasha' and 'Sesshomaru' crossover stories there. Some of the stories on Wattpad have a more modern take on the characters, which can be quite refreshing.
