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.

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.
