Definitely! Demon Slayer started as a manga. It's known for its compelling plot and well-developed characters. The manga provides the foundation for the success of the anime adaptation.
One of the great fanfictions could be those that focus on the backstories of the Hashira. For example, a fanfic that delves deep into the past of Giyu Tomioka, exploring how he became the Water Hashira. It might show his early training days, his struggles with his own abilities, and how he overcame personal tragedies. Another interesting type could be crossovers within the Demon Slayer universe, like Hashira interacting with characters from different time periods in the story in unexpected ways.
Yes, indeed. The Demon Slayer manga has gained significant recognition and has been a source of inspiration for the anime and other related media. It offers a deep exploration of the characters and their world.
