I'm impressed that Madhouse can take such a dire premise and script and execute it so well but ultimately the flaws of the material shine through too brightly. For example, I don't like how the story tries to portray the MC as someone who's not perverted yet is still gonna blatantly take erotic photos. Just seems a bit disingenuous. As if the story is trying so hard to say "Don't worry, you can enjoy all these perverted things without being called a pervert!".
Oh well, as long as there's enough of that-main-girl-who's-name-I can't-remember...
