I kinda disliked those guys that raped 21 y.o. women. They have zero taste. If you are going to commit such a crime then why even bother with old hags when you can do the whole Enjo kōsai with schoolgirls? They deserve everything whats coming their way for being filthy normies!
The guy in the first chapter on the other hand... I think we could have become best friends if he existed IRL.
I also kind of like the detective. He tries to rationalize him doing cool stuff by justice, good deeds or whatever, but deep down he is not much different than the guy from 1st chapter.
