The theme of redemption is also quite common. Since Grell has done some rather dark things in the 'Black Butler' series, many fanfictions explore whether he can find redemption. Some stories show him trying to make amends for his past actions, either through helping others or by changing his ways. And of course, the theme of friendship or camaraderie among the reapers, especially with Grell, is often explored. We see how he interacts with other reapers and how those relationships develop or deteriorate in different fanfictions.
One common theme is family secrets. Since Grell already has a rather mysterious character, adding a sister just multiplies the secrets. Another theme is identity. The sister often has to figure out who she is in relation to Grell and the other characters in the Black Butler world.
One common theme is mystery. Given Undertaker's mysterious nature in the original series, many fanfictions build on this and create a sense of intrigue around their relationship. Another is the exploration of the afterlife or the supernatural elements related to their characters. Since they both have connections to death in the 'Black Butler' world.
Well, a prevalent theme is the exploration of Grell's complex personality. Fanfics often show how the OC interacts with his flamboyant, yet deeply emotional side. Redemption is also a theme sometimes. Maybe the OC helps Grell find a new purpose or come to terms with his past actions. And of course, there's the theme of the supernatural world of Black Butler. The OC gets to experience all the dark and mysterious elements of that world through Grell, like dealing with other reapers, demons, and the afterlife in general. This makes for really exciting and often very emotional stories.
One common theme is the exploration of the relationship between Grell and the butler. It could be a love - hate relationship or a complex friendship. Another theme is the supernatural elements, as both characters often deal with the otherworldly in the original source. For example, in many fanfics, they face new supernatural threats together.
In Black Butler Sebastian x Grell fanfiction, there are several prevalent themes. The first is the contrast between their personalities. Sebastian is cool, collected and sly, while Grell is passionate, flamboyant and somewhat chaotic. Writers often use this contrast to create humorous or tense situations. Another theme is the exploration of their supernatural natures. As a demon and a Grim Reaper, they have different abilities and moral compasses. Fanfictions may delve into how these aspects interact when they are together. Additionally, the theme of 'opposites attract' is also popular, with Grell's over - the - top emotions being drawn to Sebastian's stoic exterior, leading to various relationship - based storylines.
One popular theme is the exploration of their pasts as reapers. Since both have a connection to the reaper world, fanfictions often dig into what made them who they are. Another theme is the idea of them teaming up, perhaps against a common enemy in the Black Butler universe. Their combined skills and knowledge could make for an interesting story.
A common theme is also the exploration of their different moral compasses. Sebastian, as a demon serving Ciel, has his own set of rules and goals, which are very different from Grell's as a Grim Reaper. Fanfic writers like to play with how these two characters with such contrasting ethics interact. For example, in some fanfics, they might be forced to work together on a case, which leads to a clash of their beliefs and values.
There are many 'Black Butler Grell fanfiction' that focus on his unique personality. For instance, a fanfiction might show Grell trying to improve his reaping skills in a more humorous way. He could be constantly getting into trouble while attempting to be a better reaper, like accidentally scaring away the souls he's supposed to reap. Or, a story could be set in an alternate universe where Grell is not a reaper but a normal human with his flamboyant personality intact, and how he navigates the human world.
One great fanfic could be 'The Unlikely Bond'. It delves into the complex relationship between Undertaker and Grell. It shows how their interactions change over time as they face various challenges in the Black Butler universe. The story is full of interesting twists and turns that keep you hooked.
One popular trope is the 'love - hate' relationship. Grell is head - over - heels for Sebastian, but Sebastian is mostly indifferent or even annoyed. Another is the 'rivalry' trope, as they are both strong in their own ways. Grell with his unique scythe skills and Sebastian with his demonic powers.
