As time goes on, Demon Ciel could develop a more complex understanding of the demon hierarchy. This might lead him to seek more power within the demon world. He could start to manipulate other demons to his advantage, using his wits and newfound demonic abilities. His relationship with Sebastian would also be a key factor in his evolution. If Sebastian were to face a threat, Ciel might have to step up and show a side of himself that is more protective and assertive in the demon realm.
His character evolution could also be influenced by his past as a human. Memories of his human life could resurface and create internal conflict. This might make him question his actions as a demon. He could then try to find a balance between his human values and his demonic desires. This struggle would add depth to his character and potentially lead to a more nuanced and interesting storyline. His evolution would not only impact him but also those around him in the Black Butler world.
Ciel would likely become more cold - hearted. His experiences as a human, especially the trauma he endured, would be amplified by his new demonic nature. He might lose some of his remaining humanity, such as his sense of compassion.
In fanfictions, Ciel's character development can be shown through his growing understanding of the world of demons. As he spends more time with Sebastian, he may become more aware of the true nature of power and the cost of his revenge. His relationship with other characters also plays a role. For example, interactions with his servants might make him more empathetic or, in some cases, more callous as he tries to maintain his position of power.
Female Ciel's development could also be different in terms of relationships. With other male characters, there could be a different kind of tension. For example, in a romantic context, it would be a new aspect as opposed to the original Ciel's more business - like relationships. Also, her friendship with the servants might be deeper in some ways as she might be more in tune with their emotions due to her own experiences of being underestimated because of her gender.
Well, first, you could give her a distinct personality. For example, if Ciel is more reserved and calculating, she could be outgoing and impulsive. This would create an interesting dynamic when they interact. You can also develop her backstory. Say she had a special relationship with a particular character in their childhood that influenced her actions in the present.
In this fanfic, Ciel's fear of the dark might be a manifestation of his past traumas. He has endured so much at a young age, and the dark could symbolize the unknown and the things he fears from his past, like the abuse and the loss he has faced.
In such a situation, Ciel's sense of self might be affected. He could start to question his identity as a demon and a former human. This internal struggle could make him more vulnerable. He might isolate himself from those he cares about, like Elizabeth. His relationship with Sebastian could become strained as Sebastian tries to figure out how to help Ciel. It could also lead to Ciel exploring new powers or abilities that he didn't know he had, which could have far - reaching consequences for the entire Black Butler universe.
Well, 'The Unlikely Bond' is a really good one. It focuses on how Ciel and the demon form an unexpected emotional bond that goes beyond their initial contract. The story is beautifully written and really makes you feel for the characters. 'Ciel's Journey Beyond' is also great. It takes Ciel and the demon on a journey to a far - off land where they encounter strange creatures and new cultures. This fanfiction does a great job of world - building. And 'The Demon's Secret' is a fan favorite. It reveals a long - held secret of the demon that changes the whole dynamic between him and Ciel.
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.
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.
Another theme is the struggle between Ciel's human side and his demonic nature. Fanfics may show him grappling with his emotions, memories, and moral compass in the face of his transformation. For example, he might question his past actions and how they fit into his new identity. It makes for a very interesting character study.
