Another character that could be a main character in these fanfics is Grell Sutcliff. He might be attracted to the kittens because of their cuteness, but his over - the - top personality could lead to some chaotic and hilarious scenes. He could try to dress the kittens up in fancy outfits or involve them in his wild schemes. And of course, the Undertaker might also play a role. He could be interested in the kittens because they might hold some kind of secret related to death or the afterlife in the Black Butler universe.
One main theme could be loyalty. Just as the main characters in Black Butler show loyalty to each other, the kittens might also display loyalty to a particular character, perhaps following them around everywhere and protecting them from harm.
Sebastian Michaelis could also be a main character in some fanfics. His demonic nature and loyalty to Ciel can create interesting interactions with Vintaker. Their different motives and abilities can lead to intense confrontations or unexpected alliances in the fanfic.
One idea could be a fanfic where the kittens in Black Butler have special powers. For example, they can communicate with spirits and help Sebastian solve mysteries that are related to the supernatural world in the Black Butler universe. Another idea is a story about the kittens' origin, perhaps they were created by some ancient magic long forgotten in the series' lore. They could be key to unlocking a hidden power or secret within the Phantomhive manor.
Since it's a 'Black Butler' fanfic, likely Ciel Phantomhive and Sebastian Michaelis would be important characters. And of course, the girl in the garden would be a main character as well. There could also be other characters from the original 'Black Butler' series that might make an appearance depending on the plot of the fanfic.
The main characters in 'Black Butler Girl in the Trunk Fanfic' would most likely start with the girl in the trunk herself. She could be a new character entirely made up for the fanfic. However, in relation to the 'Black Butler' world, we can assume that Ciel and Sebastian would be important. Ciel, as the head of the Phantomhive household, and Sebastian, his ever - loyal butler. There could also be other characters from the original 'Black Butler' series that are brought in to interact with the new character, like the other servants in the Phantomhive mansion or characters from the underworld that the story might explore.
Another important character is Grell Sutcliff. He's a reaper. Grell has a flamboyant personality and his own goals and desires which often intersect with the affairs of Ciel and Sebastian. His presence adds a lot of chaos and mystery to the 'Black Butler stories'.
The kittens usually lighten the mood. Black Butler is a rather dark and gloomy story, but the presence of kittens can add a touch of cuteness and innocence. It's like a ray of sunshine in a dark place.
One popular storyline is where the kittens in the Black Butler universe have special powers. For example, they might be able to communicate with spirits, which adds an interesting twist to the already dark and mysterious world of Black Butler. Another is a story where the kittens are actually key to solving a big mystery that Ciel and Sebastian are facing. They could hold clues that no one else has access to.
One interesting 'Black Butler Kittens Stories' could be about how the kittens in the Black Butler world interact with the main characters. Maybe they playfully disrupt Ciel's important meetings, adding a bit of chaos and cuteness to the otherwise serious setting.
Ciel and Sebastian are central, but other important characters from the side story include the servants in the Phantomhive manor. There's Bardroy, the cook with a past in the military. Finny, the gardener with superhuman strength. Mey - Rin, the clumsy yet endearing maid, and Tanaka, the wise old butler. They all add to the charm and complexity of the Black Butler Side Story.
