1.) Artificial Enemy
This episode established that Shaft was animating it a bit more than it needed. (They even put the hand there.) Also - as most animes do - it differs from the manga and songs. It puts in Ayano and Shintaro scenes, and changes Shintaro's room from a small room to a gigantic one, complete with a big window. It also changes his computer from a regular size to an enormous screen, gives the terrorists freaky Joker masks, and throws Seto into the terrorist scene just for the fun of it.
Also, since this is the anime fanclub, some of you may not know what this is. There's a wiki for it. No worries. :)
~Rumors that might be true (Idk for sure)
So I read on a reblogging site that Mekaku City Actors will be only 13 episodes. Really. The manga doesn't seem to be even halfway done with it's plot, and it's at chapter 20. They should make 2 or 3 seasons, because if they end it with a "read the manga" ending, I'm going to get really annoyed. :/
