What a fizzle ending this series had. The art quality was all over the place too, and I don't think I could call it particularly good at any time throughout. In retrospect, this probably would have been a much better story, presentation-wise, if it was in actual hentai format, showing real sexual situations, instead of this pseudo-vanilla crap it became. The world-building was definitely lacking, and the whole setting felt pretty isolated. Even though the pervert power system was fairly interesting, the powers themselves seemed too limited for the purpose of saving all of humanity. All in all, this was a very mediocre story, and especially towards the end it bore all the signs that edition sales were shitty, so the author was ordered to wrap it up quickly.
