Kaneki and Touka could be in a situation where they have to team up with some former enemies to save the ghoul community from a new threat. This would test their ability to forgive and their leadership skills within the community.
One possible scenario in a fanfiction could be that after a long and arduous battle against the CCG, Kaneki and Touka find a moment of peace. They look into each other's eyes, realizing how much they've been through together. Then, slowly, Kaneki leans in and their lips meet. It's a tender and passionate kiss that symbolizes not only their love for each other but also their hope for a better future in the dark world of Tokyo Ghoul.
In fanfiction, Kaneki and Touka's love is often portrayed as a deep and complex bond. They've both been through so much trauma in the Tokyo Ghoul world. Their love can be seen as a source of healing for each other. Kaneki, with his internal struggles, finds solace in Touka's strength and determination. Touka, on the other hand, is drawn to Kaneki's kindness beneath his tortured self. Fanfic writers explore how they support each other, grow together, and face the challenges of their ghoul - human coexistence world side by side.
A fanfiction might explore the idea of Kaneki and Touka's married life in a more comical way. Maybe they argue about who does the dishes, as ghouls don't really have normal eating habits. Or they have to deal with their friends constantly dropping by unannounced. Their relationship would still be full of love, but these little everyday situations would add a touch of humor to their married life.
One possible fanfiction could focus on Kaneki and Touka building a life together after the chaos in Tokyo. They might start a small coffee shop where they can interact with both ghouls and humans in a more peaceful way. This could be a symbol of their hope for a harmonious co - existence between the two species.
Common themes in fanfictions about their love include growth. Both Kaneki and Touka grow as individuals because of their relationship. They become more empathetic and stronger. Another theme is the exploration of the forbidden. Their love is a bit of a taboo as a ghoul - human relationship (even though Kaneki is half - ghoul). It adds an element of excitement and danger to their story. And unity is also a theme, as they unite against the forces that try to tear them apart and the discriminatory world around them.
Love and acceptance are very common themes. Given that Kaneki is a half - ghoul and Touka is a full ghoul, their relationship often explores how they accept each other's differences.
In some fanfictions, Kaneki and Touka team up with other ghouls to fight against a common enemy that threatens the existence of all ghouls. Their relationship is a key factor in bringing the different ghouls together and leading the fight.
There's 'Under the Moonlight'. This fanfic focuses on the more emotional side of their relationship. It shows Kaneki and Touka dealing with their past traumas while falling deeper in love. It has great character development and some very touching scenes that will make any fan of the couple happy.
For Kaneki, it would likely make him more protective. He's already been through so much, and now with a child on the way, he'd be even more determined to keep his family safe. Touka, on the other hand, might become more nurturing. She has always been strong, but the pregnancy could bring out her softer side as she prepares to be a mother.
