Love and loyalty are common themes. Often, these fanfics explore how Lizzy's love for Ciel endures despite his dark secrets. Another theme is growth. Ciel may grow as a person because of Lizzy's influence, and vice versa.
Adventure could also be a theme. Writers might put Ciel and Lizzy in various adventurous situations where they have to rely on each other and their relationship deepens as a result. For example, they could be on a quest together to solve a mystery or defeat an enemy. This not only adds excitement to the story but also gives more depth to their relationship.
In some ciel x lizzy fanfictions, there is a theme of self - discovery. As they interact more, they learn more about themselves. Ciel might discover a softer side of himself because of Lizzy, and Lizzy might find more strength in herself. Also, the theme of loyalty often comes up, as they prove their loyalty to each other in different situations in the stories.
The plot also matters. A fanfic could be about their relationship evolving during a dangerous mystery they have to solve together. This gives the story an exciting backdrop and allows for interesting interactions between the two characters. It should have a good balance between their personal relationship growth and the external events happening around them.
The theme of power dynamics is quite common too. In undertaker x ciel fanfic, we often see how the power balance between them shifts. Ciel, as a young noble with his own authority, and the Undertaker, with his unique skills and knowledge, interact in ways that show a constantly changing power dynamic. And there's also the theme of trust, as they have to learn to trust each other in many of these fan - created stories.
In Ciel x Pluto fanfics, a frequent theme is protection. Since Ciel is in a rather dangerous world, Pluto's role in protecting him can be a central part of the story. Also, the theme of mystery might come up. Pluto has his own mysteries, and how Ciel deals with those or tries to uncover them can be an interesting plot in the fanfics. There could also be themes related to power dynamics, as Ciel has a certain power over Pluto, and this can be played with in different ways in the stories.
Another theme is the power dynamic. Ciel is a young noble with his own kind of power, while Undertaker is a very powerful and somewhat otherworldly figure. Fanfics play with how their different levels of power interact and influence their relationship. For example, sometimes Ciel tries to assert his authority over Undertaker, but Undertaker has his own ways of getting what he wants.
The theme of redemption also pops up sometimes. Since both characters have their dark sides, some fanfics explore the idea of them finding redemption through their relationship with each other. They might help each other overcome their past traumas and grow as characters.
The theme of transformation also appears often. The presence of the doll may change Ciel in some way, either making him more empathetic or leading him to question his own identity. This is because the doll represents something different from his normal world, and his interaction with it forces him to grow or change in unexpected ways.
Sure. One popular 'ciel x lizzy fanfic' is 'A Royal Engagement'. It beautifully portrays their relationship in a Victorian - era setting, with lots of sweet interactions between Ciel and Lizzy. Another great one is 'Lizzy's Choice' which delves deeper into Lizzy's character and how she navigates her feelings for Ciel in a complex world filled with danger and mystery.
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.
