The halves of the cursed: demons

(In progress)
I was suddenly overwhelmed by the presence of this demonic figure. "yes if you've figured it out, I am indeed a demon". he said as if he could read my mind, which he probably could. suddenly in a flash of violet and black smoke; he was standing behind me, and as if forced out of me, suddenly i was vomiting all over the ground of wherever I was. he just looked at me like I was an interesting playthings and laughed. it was a laugh that sent shivers down my spine.
