The Soul Stealer's Conspiracy

In the dark corners, nameless monsters lurk in the shadows. They are greedy and cunning, ferocious and love flesh, especially human flesh. No one knows, on a seemingly normal night, they may just be some kind of feeling flashing at the corner of the eye, or they may be an extra leg of the shadow of the wooden chair, or they may just be a slight crack in the mirror. In a place where everyone is avoiding their eyes at the same time, you might be able to peek at something, or you might not be able to see anything at all. It's all just an illusion. However, when you are sleeping soundly or when you wake up from a dream, it is best not to look alone at places you have not usually paid attention to. Every deep night, when everyone closes their eyes, only they remain vigilant. They have been night watchmen since the birth of the ghost legend, but they are unknown to everyone. Until one of them degenerates into a soul-eating monster. The young boy was also involved in the whirlpool of the incident and drifted away in the conspiracy.
