They should also consider the context. If Sebastian is crying during a battle, it could be a sign of his deep connection to the situation or the people involved. Writers can use internal monologues to show what he's thinking while crying. For example, 'Sebastian thought to himself as the tears streamed down his face, that this was a moment he never expected to feel so deeply about.' This gives readers an insight into his emotions.
Maybe it has to do with his past. As a demon, he has a long history. There could be some memories from his past life or experiences with other demons that resurface and cause him to cry. It could be related to a long - lost friendship or a betrayal he once faced.
One popular theme is Sebastian's relationship with Ciel in different AU (alternate universe) settings. For example, in a modern AU, how they adapt to a world without the traditional master - butler dynamic. Another theme is exploring Sebastian's past as a demon, like his experiences before making the contract with Ciel. And some fanfics focus on Sebastian's interactions with other characters from the 'Black Butler' universe in unexpected ways, such as teaming up with Grell for a particular task.
In many Black Butler fanfics, the relationship between Sebastian and Grell is complex. Grell has an unorthodox infatuation with Sebastian. Sebastian, on the other hand, often sees Grell as an annoyance or a tool depending on the plot of the fanfic. Sometimes, fanfic authors play with their dynamic in a humorous way, like Grell's over - the - top attempts to get Sebastian's attention while Sebastian just wants to complete his tasks for Ciel.
A good one often has well - written characterizations. Sebastian's personality should be in - line with the original anime or manga. The ticklish aspect should be incorporated in a way that feels natural to his character, perhaps as part of a light - hearted moment or a unique plot device.
There could be a lot of hilarity. Maybe they are in the middle of a demon - related task and suddenly, a magical spell makes them ticklish. Sebastian, with his pride, would try to hide it at first but Claude would quickly notice and start to tease him. This would lead to a sort of power struggle between them as they both try to maintain their composure while also trying to get the upper hand in this unexpected tickle situation.
Well, a fanfic centered around Claude and Sebastian's tickle moments might explore their personalities in a new way. Since they are both so serious most of the time, tickling could be a way to break down their usual stoic facades. It could show a more vulnerable side of them. Perhaps in the fanfic, there's a magical or accidental situation that causes them to be ticklish, and they have to deal with this unexpected and rather embarrassing situation in their own unique ways.
In 'Black Butler Sebastian x Claude fanfic', one of the main themes is the exploration of their complex personalities. They are both mysterious and have their own motives. This is often explored in detail. Another theme is the idea of loyalty. Their loyalty to their masters can create interesting conflicts and situations. And a third common theme is the concept of the supernatural world they inhabit. The rules and hierarchies of the demon world are often part of the stories.
One common theme is family loyalty. Since it's about Sebastian's sister, her loyalty to Sebastian or vice versa is often explored. For example, in many fanfics, she will go to great lengths to protect him or keep his secrets.
One common theme is the power imbalance. Sebastian is a powerful demon, and Ciel is a young, mortal master. This creates a lot of tension and interesting situations where Ciel is constantly trying to hold his own against Sebastian. Another theme is loyalty and its limits. Sebastian is bound by a contract, but his true motives are often questioned.
