The theme of redemption can also be present. Rize's actions towards Kaneki were quite cruel in the original story. Fanfictions may attempt to give her a chance at redemption, perhaps through her relationship with Kaneki. This could involve her showing remorse for what she did and trying to make amends in some way.
In fanfiction, the relationship between Kaneki and Rize can be very complex. Some fanfictions might explore their initial encounter in a more in - depth way, like how Kaneki's life was forever changed after meeting Rize. It could show his internal struggle with his newfound ghoul nature which was a result of Rize's actions.
A fanfic could focus on Rize teaching Kaneki how to fully embrace his ghoul side. She could show him how to use his powers more effectively and how to hunt without attracting too much attention. In return, Kaneki could teach Rize about human emotions and values, which she might have lost touch with over the years of being a ghoul. This exchange could lead to a deep bond between them.
In some fanfiction, their kiss might be a very passionate and intense moment. It could be described with a lot of detail, like the way their lips meet and the emotions that flood through them at that instant.
One possible fanfic could be about how Rize and Kaneki's relationship evolves in a world where they manage to overcome their differences. Maybe they start to understand each other's pain and loneliness, which were deeply rooted in their ghoul and half - ghoul existences respectively.
The kiss between Kaneki and Rize in fanfiction could hold various meanings. It could be a foreshadowing of future events. For example, it might lead to Kaneki's transformation in a different way than in the original story. It could also be a moment of passion that shows a deeper, hidden attraction between them that the original plot didn't fully explore.
One common theme is the struggle for identity. Female Kaneki, being both human and ghoul, constantly has to figure out who she really is. This is often explored through her interactions with both humans and ghouls, and how she feels like she doesn't fully belong to either group.
One common theme is love and sacrifice. Kaneki and Touken's relationship is often depicted as a deep, selfless love. They might be willing to sacrifice their own safety or desires for the other. For instance, Kaneki could put himself in danger to protect Touka from a powerful enemy.
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. They both represent different aspects of Kaneki's identity and the fanfic often explores how to reconcile these different identities. Additionally, the theme of power and control can be seen, as they may fight over who gets to be in control in certain situations.
In a fanfiction where Kaneki is overpowered, he could have the power to heal the rift between humans and ghouls in a more radical way. He could use his extreme strength to force the humans to accept the existence of ghouls and also make the ghouls understand the importance of not preying on humans. His overpowered abilities would be like a shockwave that shakes the very foundation of the existing relationships and rebuilds them in a more positive way. For instance, he could create a safe zone where both humans and ghouls can live together without fear, and his overpowered presence would ensure that no one breaks the peace.
The theme of friendship in the face of adversity is quite common. They are in a world full of conflict between ghouls and humans, yet they form a connection. There's also the theme of sacrifice. In some fanfics, one may sacrifice for the other to uphold their new - found relationship or to protect the greater good in the Tokyo Ghoul universe.
