Well, this is different. I was expecting the MC to become your usual revenge seeking edgyfest protagonist, but he still looks like a nice dude who wants to do the right thing. I also liked how the demons are various kinds of monsters, lke talking skeletons and walkng trees, that's cute. But man i rolled my eyes with the "These humans are more evil than the demons", and the pace is just all over the place, that woman just accepted that the hero who killed her boss is the new demon lord and acts all friendly and even blushes, that's just bad.
Anyway, looks kinda promising, follow.
