I wasn't expecting horror episode for this anime at all. It worked out really well with all the horror elements in this episode. There were some genuinely freaky parts that got my heart racing. The subtle feeling that something was watching them, the amount of violence as well as the crazy expressions of the victims in the episode gave it an unsettling, but brilliant atmosphere. It came out of the blue to have a horror episode for an anime like this, but I loved it nevertheless, since I love watching horror anime. Definitely one of my favorite episodes so far.
