Black Butler Sebastian Sick Fanfiction: What are some interesting plot ideas?

One idea could be Paula discovers Sebastian's true nature as a demon but instead of being afraid, she tries to use it to her advantage in the complex world of the Black Butler. Maybe she asks him to help her gain more influence in the household or among the nobility. Another plot could involve a love triangle where Paula has feelings for Sebastian, but Sebastian is solely focused on his master, and this creates a lot of tension and drama.

One idea could be that Sebastian sacrifices himself to save Ciel from a powerful dark magic. In the fanfiction, as he faces death, he reflects on his time with Ciel and how it has changed him from a purely demonic being. He might have an internal monologue about the strange new emotions he has experienced.

One interesting plot idea could be a time - travel scenario. Sebastian and Ciel are sent back in time to a period in the Phantomhive family's history that is shrouded in mystery. They have to navigate the past, deal with their ancestors, and also face the fact that their actions in the past could change the present they came from. Another idea is a role - reversal. Ciel becomes the demon and Sebastian the human servant, which would completely turn their relationship dynamics on its head and lead to all sorts of comical and also thought - provoking situations. A third plot could be a crossover with another popular anime world, like they end up in the world of Naruto and have to adapt to the ninja way while still maintaining their own goals and relationship.

A plot could revolve around Female Ciel being kidnapped by a rival family who wants to use her to gain power. Sebastian then has to use all his skills to rescue her without breaking the terms of their contract. During her captivity, Female Ciel could learn more about the true nature of her enemies and find a way to turn the situation to her advantage. Or perhaps there is a ball where Female Ciel is expected to find a suitor. But she has no intention of getting married as it would interfere with her goals. Sebastian has to help her fend off unwanted suitors while also dealing with the demons and other dark forces that lurk in the shadows of the ballroom.

One plot idea could be Sebastian falling in love with a human who has the power to see demons' true forms. This creates a unique dynamic as he has to protect her from other demons while also dealing with his growing feelings. Another idea is a time - travel plot where Sebastian goes back in time and meets the love interest in a different era, perhaps in a more innocent time for him. And a third could be a story where the love interest is a powerful witch who challenges Sebastian's loyalty to Ciel in the context of their relationship.

One idea could be that Sebastian's sneeze is a sign of a strange magic affecting him. For example, a spell has been cast on him that makes him have an uncontrollable sneezing fit whenever he gets near a certain magical object. This could lead to comical situations as he tries to hide his sneezes while serving Ciel.

One idea could be that fem Ciel has to attend a grand ball and Sebastian helps her get ready in a very intimate way, like choosing the perfect dress and doing her hair, while they share some flirty banter. Another could be that fem Ciel gets into trouble with a rival noble and Sebastian uses his demonic powers in a very creative way to protect her, all while their relationship deepens. And perhaps a plot where fem Ciel discovers a secret about Sebastian's past that makes her see him in a new light and changes the dynamic of their relationship.

One plot idea could be that Sebastian's daughter has to hide her true identity in the human world while secretly trying to understand her demonic heritage. Another could be her getting involved in the affairs of the Phantomhive household in a way that both helps and complicates Ciel's plans. Maybe she has a special power that she's trying to control, which sets her on a journey of self - discovery.

One plot idea could be that the OC is a new servant in the Phantomhive household. Sebastian initially views her as a nuisance but as they interact more, a strange attraction develops. For example, during a ball at the manor, the OC accidentally spills wine on a noble guest. Sebastian steps in to save the situation and in the process, he realizes her charm and quick - wittedness.

Some fanfictions might have a plot where Sebastian's sickness makes him more vulnerable to his demonic urges. Normally, he has great control, but being ill could weaken that. This could lead to dangerous situations in the manor. There may also be a plot where a mysterious character appears, claiming to have a cure for Sebastian, but with a price that Ciel has to pay, which then creates a moral dilemma for Ciel.
