I must confess I've never heard of it until you mentioned it. Not that well-versed in the whole anime/manga world.
Really, wow then that is a helluva coincidence. Technically the full name is Shimoneta: A Boring World Where the Concept of Dirty Jokes Doesn't Exist. Basically the Public Morals comity in that already won at the start and has far more (draconian) power. Be for warned if you watch it... you may lose your appetite for cookies for a while... after the cookie scene with Anna... also your taste for bottle water... thanks to the comity and Anna.
