This is a demon slayer book.... You are from a family tree of secrets, one of them is about demons. Once the silver blade is revealed, well you can find that out.... Read ahead to discover your family's secrets and see the new generation rise. Now charge ahead with no regrets and fulfill your duty. I'm also not changing any of the main plot so if you've read or seen what happens at some point to a certain someone I'm not changing it as I've only put myself into the universe I'm not god so I'm not changing it just for Rengoku or anyone else. None of the art is mine sometimes my friend @Bigman_210 and I don't own any of the original characters from demon slayer except for Y/N who I created of my imagination with some random slayers he encounters, with also his Crow who I made.
