Overall a 13-episode series thats nothing but dark psychology. I will give this anime props in giving a decent ending despite the flatness of the characters. The characters stay somewhat static throughout the series but still allow for a decent ending. However this series has issues in comedy. I won't say it doesn't try and make you laugh to try and give you a breather inbetween extreme emotional distress situations, but it doesn't do much of anything because the jokes just kinda fell flat (like the lame jokes in this review, get my point). After reading this review with those random jokes, it did nothing to change the mood of the review so you, the reader, can catch yourself. Thats the same thing the series did. Thirteen episodes isn't enough to allow for something like that.
