One thing about NHK is that this show has low rewatchability (at least for me). Satou’s delusions turn out comedic, however dark comedy has never been one of my favorites. It was still entertaining enough though. To compare, I didn’t even manage to finish Muteki Kanban Musume, which was supposed to be real comedy. With NHK, the funny moments generally outshine the dull moments. Though there are ‘themes’ that aren’t for general viewing. It was mostly during that time when Satou was trying to make galge and really over-indulged on the porn.

NHK is actually a very sober anime. You won’t find random panty shots or fan service in this anime.

I read up to ch. 32 of the manga. I don't really plan on continuing. Although at first it became very promising, the humor was extremely funny and the wackiness of the characters even better, it slowly became one of those mind trips reminiscent of Serial Experiments Lain or Evangelion where it becomes a dialogue of thoughts that go in one ear and out the other. It doesn't surprise me that Yoshitoshi Abe (of Lain, NieA, and Haibane) illustrated the light novel.

I read less and less humor as more and more drama crept in. True, the characters are all screwed up. That can be golden material for humor; instead the mankaga tapped into the depressing areas of themselves. The more I read, the less I became interested in their outcomes.
