The series starts off okay with what seems like a standard dark vs light story. However midway through the series they throw a curve ball and from there this series kicks into overdrive with 2 fantastic episodes. The 3rd episode is mostly an action horror and does a great job at it with the intimidating villain that cuts his way through everyone in his path. Very sad well thought out ending. If I were to keep a list of the best endings in anime this would be on it. I have a weakness for parent child stories and the ending hits that weakness very hard.
