What are some interesting ideas for kuroshitsuji fanfiction?

Another idea is a crossover with 'Fullmetal Alchemist'. Ciel could be interested in the alchemy in that world and perhaps try to use it for his own purposes. Sebastian would be there to either help or hinder depending on his own motives.

A plot could involve Ciel Phantomhive being magically transported to Hogwarts. Since he's used to a world of mystery and intrigue in his own story, he might quickly adapt to the secrets of Hogwarts. He could form an unlikely alliance with Harry Potter and his friends, and together they face a new threat that combines elements from both universes, like a dark wizard who has made a deal with a demon.

There could also be a kuroshitsuji lemon fanfiction that delves into an alternate universe. In this AU, the characters have different personalities and the story could revolve around a love triangle between Ciel, Sebastian and a new character. The lemon aspect would add a touch of sensuality and passion to the complex relationships in this new world.

One interesting story could be about Sebastian from 'Kuroshitsuji' finding himself in the wizarding world of 'Harry Potter'. He might interact with the Hogwarts students and teachers in unique ways. Maybe he uses his demon powers to solve some of the magical mysteries in the castle.

One interesting story could be about Pluto's hidden past in the Kuroshitsuji universe. Maybe it explores how Pluto came to be in the service of the characters in the series. Fanfiction often takes the known elements of the original work and twists them in unique ways.

One interesting story could be about a dog OC that has a special power and gets involved in the complex world of Kuroshitsuji. For example, a dog OC that can see supernatural entities and helps the main characters in their investigations. Another could be a story where the dog OC is a stray that forms an unexpected bond with Ciel or Sebastian.

Perhaps a fanfiction where Alois and Ciel are transported to a modern - day world. They have to adapt to the new environment and in the process, they find unexpected common ground. Alois is fascinated by the technology, while Ciel is more interested in the new business opportunities. Their relationship evolves as they face challenges together in this strange new world.

Well, perhaps a concept is the power dynamics. If Harry is death in this crossover, he would likely have a great deal of power. In Kuroshitsuji, power is a major theme, especially with Sebastian's demonic powers. Harry's power as death could either clash or complement Sebastian's. This could lead to some really intense and unique storylines where the characters are forced to navigate around these two powerful forces.

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.

Well, some 'Kuroshitsuji Female Ciel' fanfictions might explore her relationship with Sebastian differently. For example, since she's female, there could be a more complex emotional dynamic. In one fanfic, she might be more conflicted about her feelings towards Sebastian, not just as a master - servant relationship but with a touch of romantic tension. Also, there could be fanfictions that focus on her growing up as a female in a male - dominated world of the Kuroshitsuji story, facing different challenges compared to her male counterpart.
