Grell is quite popular as well. His over - the - top personality and his unorthodox views make for some really entertaining reaction scenarios. He can go from being overly dramatic to having some surprisingly deep insights in fanfiction.
One interesting scenario could be the characters reacting to modern technology. For example, Sebastian might be both intrigued and a bit disdainful of a smartphone, finding it a curious yet overly complex device compared to the more straightforward tools of his own era. Ciel, on the other hand, could see it as a useful tool for gathering information quickly.
Yes, of course. Their unique personalities and relationships in the original work are the main sources of inspiration for fanfiction writers. Writers often base their stories on the existing characters' traits and the chemistry between them.
Ciel is also very popular. Picture a scenario where Ciel finds a cat and decides to keep it. The dynamic between him, a young noble with a dark past, and the cat can create some really heart - warming or suspenseful moments. The cat could either be a source of comfort for Ciel or bring new challenges to his already complex life.
Sebastian is always popular. In Black Butler Stainless fanfiction, he could be portrayed as having a special connection to stainless - steel objects, perhaps using them in his demonic tasks in a unique way.
Typically, the main characters would be the ancestors themselves. They could be the ones with special powers or unique personalities that drive the story forward.
Ciel is definitely one of the most popular. His complex personality and his tragic backstory make him a great focus for fanfiction. Writers can explore his inner thoughts and feelings more deeply. Sebastian is also very popular. His demonic nature and his loyalty (in a rather twisted way) to Ciel are fascinating aspects to write about. Grell is another popular character. His flamboyant and somewhat deranged personality offers a lot of room for creativity in fanfiction.
You could write a fanfic where the Black Butler characters react to different art forms. Suppose they visit an art museum in a modern setting. Sebastian, with his refined taste, would have in - depth critiques of the paintings and sculptures, while Ciel might be more drawn to the darker or more mysterious artworks. Or they could react to a live theater performance, with Ciel being amazed at the actors' skills and Sebastian observing the behind - the - scenes details like the stagecraft and the actors' emotions.
Sebastian Michaelis is also a key character. He is a demon who has made a contract with Ciel. He is extremely capable, with skills in combat, etiquette, and many other areas. He serves Ciel in exchange for his soul once Ciel's revenge is complete.
