Good read!
Personally I loved this show. It has a weird pace that helps contrast some of the crazier moments. I could not help but think that author is into some really weird stuff though. Call it my "I've seen the 18+ sections in manga shops" intuition, but my America bros seem to agree :P
I have not watched your youtube vid , is this the transcript for it too?
