A plot might involve a ghoul ending up in the Loud House world. This ghoul could be on the run from other ghouls or the CCG in its own world. In the Loud House, it has to hide its true nature from the Loud family while also trying to adapt. The Loud kids start to notice strange things happening around the house, like missing food (because the ghoul needs to eat). Eventually, they discover the truth and have to decide whether to help the ghoul or turn it in.
I think Lincoln Loud would be really interesting. He's used to dealing with a large family and all kinds of chaos at home. In the Tokyo Ghoul world, he would have to use those skills to survive among the ghouls. His sense of curiosity and determination could lead him to try and understand the ghouls better, and he might even try to find a way to bridge the gap between humans and ghouls, which is a major theme in Tokyo Ghoul.
Well, perhaps the ghouls from Ghoul School are on a field trip to the human world and end up in Royal Woods. They meet the Loud family and chaos ensues at first as the Loud kids are scared. But then they realize the ghouls are friendly. Together, they have to figure out how to get the ghouls back to their school before the sun rises, which is dangerous for the ghouls. And along the way, they learn about each other's cultures and make new friends.
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.
I think Luna from the Loud House would be really interesting. She has that rocker vibe which could mesh well with the spooky and unique nature of the ghouls. And then there's Spectra Vondergeist from Ghoul School. She could use her ghostly abilities to have some cool interactions with the Loud kids. Maybe she could play pranks on them that are more friendly than scary as they get to know each other.
Well, for a Tokyo Ghoul fan, reading fanfiction while being a fan of the original can be a mixed bag. On one hand, it's exciting to see how other fans' creativity expands the world. For example, there could be fanfictions that focus on the backstories of minor characters. However, sometimes the quality can vary. Some might not capture the essence of the Tokyo Ghoul world as well as others. But overall, it gives a chance to delve deeper into the fandom.
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.
You can try looking on fanfiction websites like Archive of Our Own (AO3). There are often a lot of fan-made stories about different pairings from Tokyo Ghoul, including Tsukiyama and Chie. Just search for their names in the search bar on the site.
One great fanfiction is 'The Unlikely Bond'. It really delves into the deep connection between Kaneki and Tsukiyama in a unique way. Another is 'A Shift in Dynamics' which shows an interesting change in their relationship over time.
