The theme of forbidden love often comes up as well. In the Tokyo Ghoul universe, the relationship between a ghoul and a human is generally not accepted. So, in Nishiki x Reader fanfictions, there's often the tension of this forbidden love, with the two having to hide their relationship from others, whether it's other ghouls or the CCG.
Another place to look could be Tumblr. There are many Tokyo Ghoul fans on Tumblr who might post or recommend Nishiki x Reader fanfictions. You can search for relevant tags such as #TokyoGhoul #Nishiki #ReaderFanfiction. However, the content on Tumblr can be a bit more scattered compared to dedicated fanfiction sites.
A possible fanfiction could focus on their past. Maybe they first met when Nishiki was still struggling with his own identity as a Ghoul. Kimi was the one who showed him kindness and acceptance. As time goes by, Nishiki starts to develop feelings for Kimi, but he's afraid to admit it because of the dangerous world they live in. The story could explore how he overcomes this fear.
First, their personalities. Nishiki is often seen as a bit of a rough character, while Kimi is more gentle. So showing how these different personalities interact is important. Second, the Ghoul world setting. You can include things like the struggle for food, the danger from other Ghouls and investigators. Third, their relationship development. Maybe start with a simple acquaintance and gradually build up to deeper feelings.
One common theme is the struggle for identity. The male reader often has to figure out whether they are more human or more ghoul. For example, in many fanfics, they might have human emotions but also the uncontrollable urges of a ghoul.
One common theme is power combination. Since both Naruto and Tokyo Ghoul have unique power systems, fanfics often explore how the ninja techniques and kagune powers can be used together. Another theme is the clash of cultures. The shinobi way from Naruto and the harsh reality of the Tokyo Ghoul world are very different.
One popular theme is the exploration of a forbidden love between Uta and the reader. Since Uta is a ghoul and there are many differences between their worlds, this creates a lot of tension and drama. Another theme could be the reader's journey of understanding the ghoul world with Uta as their guide. This often involves facing various challenges and prejudices in the Tokyo Ghoul universe.
One key theme could be the exploration of the 'otherness'. Uta being a ghoul and the reader being in a relationship with him. It's about bridging the gap between two different worlds. There's also the theme of secrecy. Ghouls have to hide their identity, so their relationship might be filled with secrecy and the need to protect each other from discovery. Another theme could be the acceptance of differences. The reader might have to accept Uta's ghoul nature, with all its implications like his diet and his connection to the ghoul world.
Well, start by choosing a theme. Maybe it's about the reader character's journey to accept their new life as a ghoul or their struggle against the ghoul - eating nature. Then, focus on character development. The reader character should grow and change throughout the story. As for the Tokyo Ghoul elements, use the canon locations and events to add authenticity. For instance, you could set parts of the story in Anteiku or during a fight with the CCG. Also, make the interactions between the reader character and the Tokyo Ghoul characters believable. This might require you to study how the characters in the original series interact with each other.
A common theme is redemption. Since both characters have done things they're not proud of in the original story, many fanfictions explore their journey towards redemption through their relationship with each other.
One great Tokyo Ghoul x Reader fanfiction is 'A Ghoul's Embrace'. It has a really engaging plot where the reader character gets caught up in the complex world of ghouls in Tokyo. The author does an amazing job of portraying the emotions and the struggle for survival.
