These are humans...? (Yandere KNY X OC Reader)

Note: the tittle has been changed once

In which, a being from a railo, a railo of mass distructikn and mvrder, comes to the mortal realm and is trained to be a demon slayer.
Her only goals are to find her friends and maybe someone who means a little more. As well as to return home. For after all, nothing can replace home.

But there are those out there, that will do anything to keep her from leaving them.

(Some yandere's will be quick, some will be almost immediate. This is mainly an OC x KNY NOT a Y/n x KNY story).

Warning: Many forms of abuse, disturbing thoughts and actions, obsessive behavior, descriptive gore, murder, and trauma, and cussing. If you are not comfortable with any of this, then please do not read.

The main character is female And is also non-human. The book cover is not mine, and all credit goes to original owner. I DO NOT, own demon slayer or any of the characters, aside from Lynn and her friends.

Btw: Railo's are other worlds

(If you don't like this book, you don't have to read it, so NO hate).
