Start by deciding her backstory. Maybe she was separated from her brothers at a young age and grew up in a different environment. This could influence her values and beliefs. Then, think about her relationships. Does she look up to one brother more than the other? How does she interact with other characters in the Inuyasha universe? Also, give her flaws. If she's too perfect, she won't be believable. Maybe she's a bit too trusting or has a short temper when it comes to protecting her family.
One plot idea could be that their little sister has a unique power that both Inuyasha and Sesshomaru don't fully understand. This power could attract various demons who either want to use it or destroy it. Another idea is that she gets lost in a different realm and has to find her way back while learning about her own abilities and the relationship between her brothers.
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.
Yes, there are likely some fanfictions out there with such a plot. However, the quality and nature of these can vary greatly. Some may be well - written character - driven stories, while others might not be as good.
One possibility could be that in this fanfiction, female Sesshomaru uses her demon powers to protect Naruto. Maybe she has her own motives, like she sees a kind of potential in Naruto similar to what she once saw in someone else. She could be a very strict but effective guardian, teaching Naruto new combat techniques from her own demon - related knowledge.
One great 'kagome and sesshomaru fanfiction' is 'The Unlikely Bond'. It explores their relationship in a very unique way, with Kagome gradually breaking down Sesshomaru's cold exterior.
No, it's not appropriate. Forced scenarios in any form of literature, including fanfiction, are unethical as they involve non - consensual actions. Fanfiction should be a medium for positive exploration of characters and their stories, not for promoting inappropriate and unethical content.
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.
I'm not sure if there is a specific fanfiction exactly like that. Fanfiction can cover a wide range of scenarios and pairings, but this particular one might be a bit unusual considering the nature of the characters in the original story. You could try searching on major fanfiction websites to see if such a story exists.
