There are some dedicated anime fanfiction platforms where you might be able to find Black Butler fanfiction. For example, Wattpad sometimes has fan - made stories about different anime series, and it's possible to find Black Butler ones there. However, the content quality can vary widely on Wattpad.
First, find a reliable platform like AO3 or Fanfiction.net as I mentioned before. Then, make sure you respect the authors' rights. Don't plagiarize or redistribute the fanfiction without permission. Also, if there are any rules or guidelines on the platform regarding reading and commenting, follow them.
They might have various reactions. Some characters could be amused by the creative interpretations in the fanfiction. For example, Sebastian might find it interesting to see how fans perceive his relationship with Ciel in different ways.
You can start by checking out popular fanfiction platforms like Archive of Our Own (AO3). It has a large collection of 'Black Butler' fanfics. Just use the search bar and type in 'Black Butler'. Another option is FanFiction.net. Look for the ones with high ratings and a lot of reviews. They usually indicate good quality fanfics.
Definitely not. The Black Butler series has a set of established themes such as the supernatural elements, the Victorian - era setting, and the complex character relationships. The idea of a 'leashed slave story' is completely foreign to the official canon and is likely a disturbing creation outside of the proper series. It would go against the overall tone and moral framework of the official work.
There is indeed a 'Black Butler' visual novel. It features the same dark and alluring art style as the anime and manga. The visual novel might include different storylines, some of which could be exclusive to this format, providing a new perspective on the 'Black Butler' world. It often has a strong focus on character development and the complex relationships within the story, which is great for fans who want to explore more about the characters.
