Good guy follows the law. Good guy gets stabbed. Bad guy doesn't follow the law. Bad guy can play dirty. Bad guy doesn't get stabbed. Alas, poor MC.
Also, ugly people should be beautiful on the inside to balance it out, for Pete's sake. Kill this demonic bitch with black scleras. Killing someone just because you're envious of them. That's one of the top 10 shittiest things you shouldn't do as a human being.
Also, seriously? You had to introduce some weird guy in a onesie as a CompSci genius. That killed the whole realism of this manga for me. That is straight up out of a Hollywood movie.
