What are some popular themes in Kuroshitsuji fanfic?

Well, some 'kuroshitsuji lemon fanfic' could explore different alternate universes within the Kuroshitsuji world. For example, they might change the setting or the circumstances of the characters' meetings. These fanfics often attract readers who are looking for new and creative takes on the original story, while also adding elements of romance or drama that might not be as prominent in the official work.

Some fanfictions explore the concept of Sebastian's true nature as a demon and how it affects Ciel. For example, his demonic abilities might both protect and endanger Ciel at the same time. The theme of revenge also comes up a lot. Ciel's quest for revenge and how Sebastian aids him in it can be a central plot. There's also the theme of sacrifice. Whether it's Ciel sacrificing something to keep Sebastian by his side or vice versa, it adds an interesting layer to the stories.

One common theme is the clash of different power structures. In 'ao no exorcist', there are exorcist powers and demon - slaying swords, while in 'kuroshitsuji' there are demon contracts. When these two worlds cross, seeing how the characters with different power sources interact is a big theme.

One common theme is the forbidden love. Since Sebastian is a demon, a relationship with a human (the reader) is against the natural order. Another theme could be the power dynamic, as Sebastian has a lot of power and the reader may be in a more vulnerable position. And of course, there's the theme of mystery, as Sebastian's true motives and the nature of his relationship with the reader are often explored.

One common theme is the power dynamic. Ciel, as a human, has power over Sebastian in the sense of their contract, but Sebastian's demonic powers far exceed Ciel's. Another theme is loyalty and betrayal. There's always the underlying question of whether Sebastian will truly fulfill the contract or if he might find a way to betray Ciel. Also, the theme of revenge is prominent as Ciel is seeking revenge for his family's death and Sebastian is a key part of that journey.

One common theme could be friendship development. Since they are both characters in the Kuroshitsuji universe, their relationship might start as acquaintances and grow into a deeper bond in fanfics. Another theme might be adventure, where they go on some sort of journey together.

Some 'dark kuroshitsuji fanfiction' stories focus on alternative timelines where things take a much darker turn. Maybe Ciel fails in his revenge and descends into complete despair, or Sebastian betrays Ciel in a more sinister way than in the original story. These types of fanfictions often play with the psychological and emotional darkness of the characters, showing how they could be pushed to their limits and beyond.

One interesting concept could be a crossover with other Victorian - era related works. It might bring in different characters and storylines from that time period, adding more depth to the Kuroshitsuji universe. For example, a crossover with Sherlock Holmes - like characters could lead to some exciting detective - related plots within the Kuroshitsuji world.

Sebastian is often a popular choice. His demonic nature and his loyalty (in a rather twisted way) to Ciel make him a very interesting character to cross over. He can easily interact with characters from other dark or supernatural works, and his powers and suave personality can add a lot to a crossover story.

It's quite popular. A lot of people love it for its unique story and art style.
