Kby Stories

What happens if I just add in my Original Characters in the world of Demon Slayer? The Story gets modified, distorted, changed. Fates may change, Fates may stay. This is a Story of my Original Characters, Tsubaki, Tsutomu, Takeru and Takumi Ryuzaki. Four Siblings orphaned at a young age who turn in Demon Slayers years later. Canon Characters are, of course, involved. (Warning!! Manga Spoilers in Future Chapters!)
