Romance is also a big theme. A female Ciel might be paired with different characters in new and interesting ways. It could be with Sebastian in a different dynamic than in the original, or with other characters from the 'Black Butler' universe. Writers often explore how a female Ciel's relationships would develop in terms of love and friendship.
One common theme is the exploration of gender roles. Since Ciel is male in the original but is female in these fanfictions, it often delves into how different her experiences would be in the Victorian - era setting of the story. For example, how she might face different social expectations compared to her male counterpart.
Well, a frequent theme is the exploration of Ciel's femininity. It might be about how she balances her female identity with her role as the head of the Phantomhive family. Also, there's often the theme of how other characters perceive her differently as a girl, which can lead to new storylines and conflicts.
One common theme is the exploration of power dynamics. Sebastian is a powerful demon and Ciel, even as a female in these fanfictions, often has her own form of power, be it through her position or her own wits. Their relationship is often a dance of power, with Sebastian being dominant but Ciel trying to assert herself in different ways.
One common theme is mystery. Ciel's own past and the secrets of the Phantomhive family often play a big part. Another theme could be revenge, as Ciel is on a quest for vengeance in the original story. And there's also the theme of loyalty, like the loyalty of Sebastian to Ciel which might be further explored or twisted in fanfiction.
A less common but still interesting theme is role - reversal. Some fanfictions might have Elizabeth taking on a more active or dominant role, perhaps in protecting Ciel or being involved in the more dangerous aspects of his world. This can bring a fresh perspective to their relationship and the 'Black Butler' universe as a whole.
One common theme is forbidden love. Since Ciel is in a complex social position, falling in love with someone outside of what is expected can create a lot of drama. Another theme is love as a form of redemption. His love for someone might make him question his own actions and motives, leading to a change in his character.
One common theme is mystery. Since Ciel is involved in many mysterious affairs, his birthday could be the backdrop for a new mystery to unfold. For example, a mysterious guest arrives at the manor with a cryptic message related to Ciel's past. Another theme is loyalty. His servants' loyalty to him is often a big part of the 'Black Butler' story, and on his birthday, they could show their loyalty in special ways, like protecting him from a potential threat. Power is also a theme. Ciel's power struggle in the underworld could be highlighted on his birthday, as he might receive offers of alliances or face challenges from his rivals.
One common theme is Ciel's relationship with his servants in a cute way. For example, how they take care of him in an endearing manner, like Sebastian making his favorite tea just the way he likes it and the comical interactions that follow. Another theme could be Ciel's childhood memories, perhaps showing a more innocent side of him before all the darkness in his life. It gives a different perspective on his character.
Well, a frequent theme is the exploration of their relationship. It could be the development from a simple master - servant relationship to something more profound. Redemption is also a theme sometimes, like Sebastian seeking some form of redemption through his service to Ciel. And the theme of the supernatural is always present, given Sebastian's demonic nature and the dark world they inhabit.
One common theme is loyalty. Sebastian is Ciel's butler, and in many fanfictions, this loyalty is tested in various extreme situations. Another theme is power dynamics. Sebastian has supernatural powers while Ciel has his own form of authority, and how they balance or clash with each other is often explored.
