One idea could be a post - apocalyptic scenario where Kaneki and Hide are trying to survive in a world that has become even more hostile to ghouls. They could be on a journey to find a safe haven, relying on their deep - seated friendship and Hide's unwavering loyalty to Kaneki. Along the way, they face various challenges that test 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. 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.
Their relationship could be developed in a unique way by having Hide become a ghoul. This would completely change the power dynamic between them and force them to re - evaluate their friendship. They would have to learn to understand each other from a new perspective, as Hide now experiences the same struggles as Kaneki.
Many Kaneki x Tsukiyama fanfics also tend to be set in the dark and gritty world of Tokyo Ghoul. The setting adds to the overall atmosphere of the relationship. The fanfics might include elements like their interactions within the ghoul society, their battles together or against each other, and how these experiences shape their relationship. For example, a fanfic could show how they bond over a shared enemy or a difficult situation in the ghoul underworld.
I've heard of a fanfic named 'Eyes of the Self'. In this one, the two Kanekis are constantly at odds, yet they also have a deep understanding of each other. It's really well - written, with great descriptions of their internal battles. There's also a fanfic that's more action - oriented called 'Battle of the Kanekis' where they fight against a common enemy while also dealing with their own relationship. And 'The Kaneki Bond' is a heart - warming fanfic that shows the bond between the two Kanekis growing over time.
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.
One common theme is the exploration of their complex relationship. Given their different personalities and backgrounds within the Tokyo Ghoul universe, fanfics often focus on how they interact, whether it's a love - hate relationship or a gradual understanding and acceptance.
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.
One idea could be a fanfic where a human character tries to form a peaceful co - existence pact with the ghouls. They might start by secretly helping a friendly ghoul and gradually work towards getting both sides to understand each other better.
One popular 'Tokyo Ghoul Tsukiyama x Kaneki' fanfic is 'A Different Kind of Bond'. It explores their complex relationship in a post - apocalyptic Tokyo. The author delves deep into their psychological states, showing how they rely on each other in unexpected ways.
One idea could be that the reader is a new ghoul in the area and Naki takes it upon himself to show them the ropes. Maybe he teaches them how to hunt without getting caught. Another plot could involve the reader being injured and Naki protecting them from other ghouls who might see them as easy prey. A third plot idea is that the reader has a special ability that Naki discovers and they team up to use it for their survival in the harsh ghoul world.
