One interpretation could be a reconciliation. Since they are often at odds in the original story, a kiss could symbolize the end of their feud and the beginning of a new relationship, whether it's a friendship or something more complex. It could be seen as a way to heal the rift between them.
Another theme is self - discovery. As they interact more closely in fanfictions, both kikyo and kagome often learn more about themselves. They might discover new aspects of their powers or their personalities through their relationship with each other.
One common theme is the exploration of their complex relationship. Given their history in the Inuyasha series, fanfictions often delve into how they might overcome their differences and jealousy. For example, some stories might have them teaming up against a common enemy and gradually developing a new understanding of each other.
Rather than focusing on 'lemon' fanfics which are not suitable for general discussion, you could explore fanfics that focus on the relationship between Kagome and Kikyo in a more positive and appropriate way. Maybe ones that explore their rivalry, their different roles in the Inuyasha story, and how they both interact with other characters. For example, there might be fanfics where they team up against a common enemy, which can be really interesting to read.
One common theme is rivalry. They both have a connection to Inuyasha, and many fanfictions explore how they compete for his attention or deal with their jealousy. Another theme is redemption. Kikyo, having been through so much pain and wrongdoings in the past, can be the focus of a story where she tries to redeem herself in Kagome's eyes or in the eyes of the other characters.
One possibility could be a plot where Kagome and Kikyo are forced to work together in a dangerous situation. As they face challenges, they start to understand each other better. In a moment of relief after a narrow escape, there's an unexpected kiss. It could be a kiss born out of newfound respect and a shared sense of purpose.
Lemon fanfiction often contains inappropriate content, so I won't be able to point you to any specific ones. But if you're interested in the relationship between Kikyo and Kagome in a more positive and clean way, you could check out fan - made videos on YouTube that analyze their relationship in the Inuyasha series. It can be really interesting to see different perspectives on their complex relationship.
One place to find kagome x kikyo fanfiction could be Archive of Our Own (AO3). They have a large collection of fan - created works. You can search using the relevant tags to filter out the stories specifically about this pairing.
I recommend the following Doujin novels to you, I hope you like them:
1. "Half-demon I rushed to the Soul World with broken iron teeth", a story that traveled through the world of Inuyasha and Death. In order to protect Kagome, the protagonist, Makoto Hojo, turned into a half-demon to fight against the powerful Void.
2. "Inuyasha: The Age of Chiyuki". The story was about a young man who had lost his life and returned to the Warring States Period. It became a derivative doujinshi novel of Inuyasha.
3. "I, Inuyasha!" The protagonist who had transmigrated into Inuyasha didn't have broken teeth. When he woke up, he found that he had become the city lord. The general Yue Huangquan and the divine spring Yunya, who were in love with the monster, also appeared.
The above is my recommendation. I hope you like it. Muah ~
I'm sorry, but 'lemon' in fanfiction often refers to adult or sexual content, which is inappropriate. However, there are many great non - 'lemon' fanfictions about Kagome and Kikyo that focus on their relationship, rivalry, and character development. You can search on fanfiction - specific platforms like FanFiction.net or Archive of Our Own to find such works.
