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.
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.
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.
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.
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 interesting female Kaneki fanfiction could be one where she forms an unexpected alliance with a group of ghouls from a different territory. In this story, she might use her unique perspective as both human and ghoul to bridge the gap between different ghoul factions. It could explore her internal struggle in a new light as she tries to maintain her humanity while also fitting into the ghoul world.
One possible fanfiction could be where Kaneki, after fully mastering his ghoul powers, becomes a sort of protector in the ghoul world. He could use his strength to keep the balance between humans and ghouls, defying the traditional enmity. He might be able to create new rules that both sides can abide by, making the world a more harmonious place for both species.
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.
