PS1:

Do you think this is a brainless and harem-covered anime doujinshi?

Do you think this is a novel that is fun to complain, has no morals, has no lower limit, and only sells cuteness and pretends to be stupid?

Do you think this is a dark and curious, bloody, tyrannical and inhumane killing movement?
