Who would be the most interesting character to focus on in 'Black Butler in Our World' fanfiction?

Sebastian would be really interesting. His demonic nature and his ability to adapt to different situations in 'Black Butler' would make him stand out in a crossover. He could use his skills to either help or manipulate the characters in 'Tokyo Ghoul'. His loyalty to Ciel in his own series could be contrasted with his new relationships in the 'Tokyo Ghoul' world, and it would be fascinating to see how he uses his powers to deal with ghouls.

I think Grell would be really interesting. In the real world, Grell's flamboyant and over - the - top personality would create a lot of chaos. He could be a fashion designer or something similar, still with his love for the color red and his chainsaw. His interactions with Sebastian would be hilarious, as Sebastian would be constantly trying to keep him in line while also dealing with the real - world problems.

Sebastian would be the most interesting. His demonic nature and his loyalty to Ciel would bring a whole new dynamic to the Avengers. He could easily outmaneuver most of the villains with his wits and powers.

Ciel and Dean Winchester would be an interesting pairing. Ciel is a young, determined noble who is used to getting his way, while Dean is a tough hunter with a lot of experience. They could learn from each other's ways of dealing with difficult situations. Ciel could teach Dean some of his strategic thinking, and Dean could show Ciel how to handle more physical threats.

One more interesting pairing could be Undertaker and America. Undertaker's mysterious and somewhat macabre nature against America's bold and brash attitude. America might be curious about Undertaker's strange hobbies and Undertaker could be intrigued by America's naivete and strong sense of justice. It would be fascinating to see how they interact, whether they become friends or end up at odds with each other. Also, Mey - Rin and Japan could have an interesting dynamic. Mey - Rin's clumsy but kind - hearted nature and Japan's reserved and traditional ways could lead to a unique relationship where they learn from each other.

Natsu from Fairy Tail would be a great character to focus on. His dragon - slayer magic and hot - headed personality would make for some exciting interactions with the characters from Black Clover. He could have friendly rivalries with the Magic Knights, especially those with powerful fire - based magic. Also, his loyalty to his guild and friends could be a driving force in a story where he has to cooperate with Black Clover characters to save both worlds.

Angela would be a great character to focus on. She was such a strong and independent character. In a reunion, we could see how she has balanced her career and personal life. Maybe she has traveled the world and has amazing stories to share, and how her relationship with Shawn has either deepened or changed in unexpected ways.

One concept could be that Sebastian and Ciel are transported to modern-day London. Sebastian has to adapt to modern technology like smartphones while still serving Ciel. Another idea is that a modern-day detective discovers the existence of the Black Butler world and gets involved in their affairs. And perhaps a fanfiction where Ciel attends a modern school undercover and has to deal with bullies and normal school problems while Sebastian tries to keep his identity a secret.

Sebastian and Malleus Draconia would be an interesting pairing. Sebastian is a demon with his own set of skills and motives, and Malleus is a powerful fae. Their interactions could be filled with power plays and attempts to outwit each other. They both have an air of mystery and superiority, which would make for some great scenes.

Ciel would be a very interesting character to cross over. He has a dark past and a complex personality. In the Beauty and the Beast world, he could be a catalyst for change. Maybe he could see himself in the Beast and try to help him in ways that the other characters in Beauty and the Beast couldn't. Ciel's experience with dealing with demons and the supernatural could also be used to figure out the mystery behind the Beast's curse. And his relationship with Sebastian would add another layer of complexity to the story.
