One common theme is the exploration of a different power dynamic. Since Kaneki is male in the original, making her female changes how she might interact with other characters in terms of power struggles.

One common theme is identity. Since it's a female version of Kaneki Ken, the fanfiction often explores how her gender affects her identity as a ghoul. Another theme is relationships. There are different takes on how she interacts with other characters like Touka or Hide.
A common theme is romance. Since Ken Kaneki is a complex and interesting character, many female - authored fanfictions explore a romantic relationship between a female character and him. Another theme is friendship. Female characters might form deep friendships with Ken Kaneki and support him through his struggles. Also, self - discovery is often there. Ken Kaneki's own journey of finding out who he is as a half - ghoul can be paralleled with a female character's journey in some fanfictions.
One common theme could be the exploration of their relationship dynamics. Since they are both characters from Tokyo Ghoul, their different personalities and experiences within the Tokyo Ghoul universe might be explored.
One common theme is survival. Given the nature of their world, they often have to fight to survive together, which strengthens their bond.
Self - acceptance is a very prevalent theme. The two Kanekis need to come to terms with their own existence and their relationship with each other. Identity crisis is also common.

Given that they are the same character in different states, fanfics might delve into how they interact with this shared yet distinct self - awareness.

One idea could be a crossover with the 'Harry Potter' universe. Ken Kaneki could be a new student at Hogwarts, dealing with his ghoul powers while also learning magic. Another could be a crossover with 'Attack on Titan', where he helps the Scouts fight Titans, using his unique abilities. Or perhaps a crossover with 'My Hero Academia', where he attends UA and has to navigate the world of heroes and villains.
Another theme is the power dynamic. Kaneki gains power throughout the series, and Tsukiyama is also a powerful ghoul. Fanfics often play with how this power dynamic affects their relationship, whether it's a source of conflict or a way for them to bond and support each other.
