The theme of mystery also crops up a lot. Since the Black Butler universe has a lot of mystery already, fanfictions might add more. For instance, there could be a mystery surrounding Lizzy's family and how it ties into Ciel's past. This makes the readers keep reading to find out the truth.
There's also 'Ciel and Lizzy: A New Chapter'. This fanfiction takes a different approach. It starts with Ciel and Lizzy getting into an argument over a decision Ciel has made. But through the course of the story, they come to understand each other better. The writing style is engaging and it keeps you hooked from start to finish.
One popular theme is the power dynamic between Ciel and Alois. Given their different personalities and backgrounds in the Black Butler universe, exploring how they interact in a yaoi context can be fascinating. For example, Ciel's more reserved and calculating nature against Alois' more erratic and desperate personality creates an interesting contrast that many fanfiction writers like to play with.
A fanfic could show a moment where Ciel is at his most vulnerable, and Lizzy is the only one there to comfort him. Perhaps after a particularly difficult encounter with a foe, Lizzy finds Ciel in his study, and she simply holds him without saying a word, which means a great deal to Ciel.
A fanfic might explore their relationship in a different time period. For example, what if they were children again? They could have innocent playdates that gradually reveal their deep - seated feelings for each other. Ciel might be less guarded around young Lizzy, and she could bring out his softer side.
One common theme is Lizzy's growth and development. Writers often explore how she becomes stronger and more independent in different scenarios, especially in relation to her relationship with Ciel. For example, some fics show her learning self - defense skills to better protect herself and those she cares about.
The theme of mystery is quite prevalent. There are always secrets between Sebastian and Ciel. Sebastian's true nature as a demon and his long - term plans are often a mystery. In fanfiction, this mystery is sometimes deepened or resolved in different ways. And the theme of sacrifice can also be found. Ciel might have to sacrifice parts of his humanity to achieve his goals with Sebastian by his side, and Sebastian may also have to sacrifice some of his demonic desires for the sake of the contract.
One popular theme is the complex relationship between Ciel and Sebastian. It often explores the power dynamics, with Sebastian being a demon bound to serve Ciel. Another theme is the dark and mysterious world they inhabit. Many fanfictions delve into the supernatural elements of the Black Butler universe, like the existence of other demons and their motives. Also, the idea of Ciel's revenge and how Sebastian aids him in that quest is a common theme. It shows how their goals are intertwined despite their very different natures.
One common theme is identity. Since Ciel already has a complex identity, adding a twin doubles that complexity. Another theme is family, exploring the relationship between the twins and how it affects their actions.
One common theme is the exploration of gender roles. Since Ciel is female in these fanfictions, it often shows how she defies or conforms to the Victorian era's expectations of women while dealing with the underworld and supernatural elements. For example, she might have to balance her ladylike image with the need to be a strong and decisive leader like the male Ciel was.
Family or surrogate family is also a theme. Given Ciel's tragic family situation in the original, fanfictions may introduce new characters or develop existing relationships in a way that gives baby Ciel a sense of family. For instance, some stories might have the servants of the manor taking on more parental roles towards the baby Ciel, creating a warm and loving environment for him to grow in.
