One great fanfiction is 'Sesshomaru's Unexpected Bond with Kagome'. It beautifully weaves a story where their relationship develops in a unique way. The author's description of their interactions is very engaging.
Friendship is a big theme. How they start from being at odds, especially considering Sesshomaru's initial disdain for humans like Kagome, and gradually develop a bond of friendship. Some fanfics also focus on the power dynamics. Since Sesshomaru is much more powerful than Kagome in terms of physical strength, how they balance that in their relationship, whether it's through Kagome's intelligence or spiritual abilities, is also a common theme.
Yes, there are quite a few. One great way to find them is to search on Tumblr. Many fans share their favorite sesshomaru x kagome fanfictions there. Some of these fanfictions may show sesshomaru protecting kagome in dangerous situations, which gradually makes kagome see a different side of him. This could be the starting point of a special relationship between them in the fanfiction world.
One common theme is the idea of 'opposites attract'. Sesshomaru is often portrayed as cold and aloof, while Kagome is warm and empathetic. Their different personalities coming together is a popular concept.
Common themes include the power dynamic between them. Sesshomaru is a powerful demon and Kagome has her own spiritual powers, so how they interact in terms of power is often explored. Friendship is also a theme that can develop into something more. As they face various challenges in the Inuyasha universe, they start to rely on each other, which can lead to deeper emotional connections. And sometimes, there's a theme of redemption for Sesshomaru, with Kagome being a part of that journey.
One common theme is the growth of their relationship. Starting from distrust or indifference, they gradually come to understand and care for each other. Another theme could be adventure. They might go on quests together, facing various demons and challenges, which brings them closer. Also, the theme of cultural clash might be present, as kagome is from a different time and has different values compared to sesshomaru.
I really like 'A Different Path'. In this fanfic, kagome and sesshomaru are forced to team up due to a common enemy. The story is full of interesting dialogues between them as they struggle with their new - found partnership. It also delves into their individual growth as characters as they deal with their feelings for each other.
The theme of 'growth and acceptance' is also prevalent. As they interact, both kagome and sesshomaru often have to grow as individuals to accept their feelings for each other. They need to overcome their prejudices and past experiences, which makes for a very engaging read.
I'm not sure specifically about 'dark lemon' fanfiction involving them as it often involves inappropriate and non - canon content. However, there are many regular Kagome and Sesshomaru fanfictions that explore their relationship in different ways, such as on fanfiction.net or Archive of Our Own. You might want to focus on those for more positive and in - line - with - the - original - spirit stories.
The theme of sacrifice could be present. Sesshomaru might have to sacrifice his solitary lifestyle and some of his pride to be there for Kagome and the baby. Kagome may have to sacrifice her own plans and dreams for a while to focus on the pregnancy. Additionally, the theme of unity could be explored as they have to be united in facing the challenges that come with her pregnancy, such as potential threats from other characters who don't approve of their relationship.
