My precious demon lord~

My demon lord--> Kibutsuji-sama

Everyone...
This is my first smut story.
I think maybe because of my dirty brain, it might be bad.
Plz bring 10l of holy water to cleanse my horny brain. Arigato.

This story is about a young girl called (y/n) Kamisato from Tokyo. She was abandoned by her parents until a hashira adopted her. She then joined the Demon Slayer Corps, she was a tsugoku.
She was on a mission until she met up with the founder of demon...
What will happen to her? Will she die?
