In 'Black Butler in Our World' fanfiction, an exciting concept could be the introduction of time - travel. What if Ciel and Sebastian travel back and forth between their Victorian era and the modern world? They could bring elements from one world to the other. For example, Ciel could introduce Victorian fashion trends in the modern world, and in return, learn about modern medical advancements to try and cure his ailments. Another concept is that of a parallel universe where the Black Butler world and our world co - exist, but there are some glitches that start to make the two worlds collide, and Ciel and Sebastian have to fix it.
One concept could be that Sebastian and Ciel are transported to modern-day London. Sebastian has to adapt to modern technology like smartphones while still serving Ciel. Another idea is that a modern-day detective discovers the existence of the Black Butler world and gets involved in their affairs. And perhaps a fanfiction where Ciel attends a modern school undercover and has to deal with bullies and normal school problems while Sebastian tries to keep his identity a secret.
In Black Butler fanfiction, a common concept is the exploration of different endings. Instead of the somewhat open - ended or tragic nature of the original, fanfics can give Ciel a happy ending, or perhaps a more complex and bittersweet one. There are also fanfictions that delve into the moral grey areas more deeply. For example, how far is Sebastian really willing to go for Ciel, and what are the implications of their contract from a moral perspective?
Well, one interesting concept could be modernizing the Victorian setting. For example, making the Phantomhive manor a high - tech mansion with advanced security systems instead of the old - fashioned one. Another concept might be the modern occupations of the characters. Instead of being a butler in the traditional sense, Sebastian could be a personal assistant with extraordinary skills in a corporate world. Also, modern OC (original character) can bring new dynamics to the story, like a modern detective OC who gets involved with the dark secrets of the Black Butler world.
One interesting concept could be being reborn as a servant in the Phantomhive household. You'd get to interact with all the unique characters like Sebastian and Ciel up close. Another might be being reborn as a noble who has some hidden connection to the underworld events that the main characters are involved in.
Well, in 'dragons in our world fanfiction', there might be the concept of dragons having their own secret societies. They could have ancient laws and traditions that are completely unknown to humans. And also, the concept of dragons being able to transform into human form to interact with society without causing panic is really cool.
One interesting concept could be the reversal of traditional gender roles. For example, female versions of male characters might display different leadership styles. In a genderbend fanfic, a female Sebastian could bring a new level of elegance and subtlety to the role, while still maintaining the character's loyalty and competence. Another concept could be the different relationships that form. A genderbent Ciel might have a more complex relationship with a female Sebastian, perhaps with added elements of friendship or sisterly/brotherly love.
One interesting concept could be how the characters' relationships change due to time travel. For example, Sebastian might have to adapt to a different era's social norms while still serving Ciel, which could add new layers to their dynamic. Another concept could be the alteration of the plot. If Ciel travels back in time, he could potentially prevent certain tragedies from occurring in his family's past, completely changing the story's trajectory.
The way OCs are integrated into the fanfiction's world is also fascinating. Sometimes they start as outsiders and gradually become an important part of the story. They can change the power dynamics or relationships within the story. For instance, an OC might befriend a character who was previously isolated, thus altering the character's arc.
Sebastian would be really interesting. He's a demon, so seeing him interact with modern - day society would be full of comical and also rather dark moments. He'd be confused by some things like traffic laws but would quickly figure out how to use his powers to his advantage in a world full of new challenges.
Well, in 'Black Butler Real Life Fanfic', a great concept is the exploration of the power dynamics. In the original, there's a clear master - servant relationship. In a real - life version, this could be seen as a relationship where one person is extremely devoted to another, perhaps in a mentorship or a very unequal friendship. Also, the dark undertones of the original, like the deals with demons, could be reimagined as dangerous or risky choices people make in real life, like getting involved with the wrong crowd for some sort of gain.
One idea could be creating a story where a new character arrives at the Phantomhive manor with a special power that Ciel is initially suspicious of but later realizes can be useful in his battles against his enemies. For example, the power to communicate with the dead, which could provide valuable information in their investigations.
