What are the best Black Butler Ciel and demon fanfiction stories out there?

I really like 'Ciel's Cat Adventure'. In this fanfiction, Ciel as a cat encounters various characters from the series in unexpected ways. It's a light - hearted read compared to some of the darker aspects of the original Black Butler, but still manages to capture the essence of the characters. It shows Ciel's intelligence even in his cat form as he navigates through different situations.

One great 'Black Butler Ciel Sebastian Fanfiction' is 'The Demon's Contract Renewed'. It explores a new set of challenges for Ciel and Sebastian in a very engaging way.

One great 'Black Butler Ciel and Sebastian fanfiction' is 'The Demon's Contract Renewed'. It delves deeper into the complex relationship between Ciel and Sebastian. The author beautifully portrays Ciel's struggle with his past and future while maintaining his pride, and Sebastian's unwavering loyalty (in his own devilish way). It's a must - read for any fan of the duo.

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 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 idea could be a fanfiction where Ciel and the demon, instead of their usual master - servant relationship, become allies in a different realm. They could be on a quest to save a parallel world that is being threatened by a powerful dark force. Another idea is a story where the demon has to protect Ciel from a group of rogue demons who see Ciel as a valuable asset due to his connection with the underworld. Maybe in this fanfiction, Ciel discovers a new power within himself that the demon has to help him control.

Yes, Ciel does become a demon in the Black Butler manga.

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 idea could be Ciel exploring his new demonic powers. He might start to see the world in a completely different way, with his values shifting as he is no longer bound by human limitations. For example, he could use his powers to seek revenge in a more extreme way than he could as a human.

The fanfiction could also focus on the visual elements. Wonderland is known for its out - of - this - world scenery and creatures. In a 'Black Butler' context, the contrast between Ciel's dark and often Victorian - era aesthetic and the bright, wacky world of Wonderland could make for some really interesting descriptions. Artists might be inspired to create some amazing fanart based on such fanfictions.
