this kind of forced elitism lowers my expectation from this series. that last dialogue is also confusing me, I can't tell who's insulting who and I don't know if this is scanlation error of author messing up
technically an animal's horn or any cartilage part are used as tools either to walk, ram, scratch etc so there's obviously no nerve there. like our nails it only hurts when cut too deep and thats it
rereading this since I forgot every premise on this series. please forgive me since other comments are about MC's former family but here I am almost dead from the first panel where an image of certain guy with same name laughing on top of a stairs popped in my head
