This is super interesting. Idk how to describe it but people be having some demon school systom and it looks so detailed yesyes. Our mc got a real powerful demon but for some reason it has an appearence as a cat.
Aggravating story. Absolutely no one here is redeemable, the plot is literally just like "oh I have to kill X amount of innocent people to be strong?? Sounds good" or even worse "i was ordered to kill innocent people so imma do that" shitty characters with shitty morals.
