After I finished watching this anime, I kind of expected how it was going to end; since many anime with harems end kind of similar in terms of romance. I found it kind of strange that the MC, who is a porno writer, easily gets nosebleeds. In my opinion, characters that get nosebleeds from witnessing something perverted are..."pure". Going off of that, if he is this pure, why is he a porno writer?
As with romance-comedy anime (harem optional), the male MC usually displays some kind of a dense personality; creating situational irony for the viewers to laugh at. This is effective for comedy in anime, but I felt that this anime over-used it a tiny bit. People that are picky with what they watch probably shouldn't watch this if they don't like the main character portrayed like this.
The setting is probably one of my most favorite parts of this anime. It sounds very original and unique. The school that contains only geniuses in all aspects of life was interesting. But, they could have focused more on the story. The story was weakened a little bit with the prominent fan-service.
Speaking about fan-service, the censoring was over-done a bit. There are many different anime that have WAY more fan-service but way less censoring.
I would recommend this anime to anyone that watches anime casually only.
