Black Butler: Fanfiction about Ciel's Little Sister - What Are Some Common Themes?

To write a great fanfiction about Ciel's little sister, start with a strong backstory. Explain how she ended up in the Phantomhive family. Was she adopted? Or is there a more mysterious origin? Build on her relationships not just with Ciel, but also with the servants. For instance, a budding friendship with Finny could show her kind - hearted side. When it comes to the plot, make it engaging. Maybe she discovers a conspiracy that threatens the family and has to use her wits to solve it. Don't forget to give her growth throughout the story. She should change and develop as she faces different challenges. And use vivid descriptions to bring her world to life, whether it's the grandeur of the Phantomhive manor or the seedy underbelly of London.

One common theme is Ciel's revenge. Since his backstory in the original series is about seeking revenge, many fanfictions explore this further. Another is his relationship with Sebastian, so there are a lot of fanfictions that focus on their master - servant dynamic in different situations.

One common theme is the exploration of Ciel's relationship with Sebastian as a demon. How their contract changes and how Ciel adapts to his new demonic nature. Another theme is Ciel's struggle for power in the underworld, as he is now a demon. It often involves him facing other powerful demons.

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.

One common theme is mystery. Ciel's eye is already quite mysterious in the original work, and fanfictions often delve deeper into it. For example, they might explore the origin of its power in more detail.

In Black Butler Alois x Ciel fanfiction, a frequent theme is the idea of redemption. Despite their often cruel actions, some fanfictions try to show a path of redemption for either or both of them. Also, the theme of rivalry is common. They compete for various things, like influence in the underworld or the loyalty of certain characters. And there's the theme of emotional turmoil, as both Alois and Ciel have deep - seated emotions that are often in conflict with each other.

One idea could be that Ciel's sister was secretly alive all along and has been in hiding, training to avenge the family. She could emerge with unique powers and a strong will, partnering with Sebastian in unexpected ways to take on the enemies that Ciel has faced.

One common theme is loyalty. Finny's unwavering loyalty to Ciel is often a central aspect. Another theme could be protection. Finny protecting Ciel from various threats, be it other supernatural beings or human enemies. Also, growth is a theme. Ciel might grow as a person because of his interactions with Finny, learning about emotions like trust and kindness that he may not have fully understood before.
