I am looking for novels where the Mc is a monster via reincarnation, natural birthing or any other circumstances. I am fine with any recommendations but I prefer one a little more scary, or at least the idea or concepts within it are scary. I have read kumodesu Chrysalis and Evolution Begins with a big tree.

I have been into the whole Mc is a monster trope recently. I'm okay if its monster evolves to human or monster stays monster, reincarnation is also fine. I just have been searching for good ones and a lot of them suck. I wanted a horror one or something that shows they are really a monster or the world around them is scary. I came here hoping somebody would know one or two.
