The Last Hashira (black butler x demon slayer crossover)(DISCONTINUED FOR NOW)

Tanjiro Kamado was an ancestor to Y/n Kamado what if she learned all the breathing techniques and be almost most likely the second Yorrichi what if she was the one to destroy Muzan's bloodline. Find out now when she's in the 18th century meeting Ciel and the other Black butler characters.(your breathing forms are mainly insect breathing, flower breathing,fire breathing, water breathing, and love breathing. (And I do not own anything except my edit for the title and storyline but other than that I do not own anything else and you might be wondering why I never say I do not own the anime or anything it's because I got tired and too lazy to write it so hope you understand.)
