This was one of the series I had been looking forward to watching ever since seeing the trailer a month ago and it didn’t disappoint. My first impression of it would be a mix of Index, Shana and FMA; two parallel worlds of human and demons, church influence and the use of magical incantations and magic circles.
Design and animation is definitely top-notched, perhaps even the best this season have to offer. The setting is simple, straightforward and a formula that works. The son of Satan that had been raised human finally finds out the secret behind his birth and rather than rejoining the evil side, he decided to be part of the Exorcist group in order to get revenge for his human father.
I’ve also heard great things about the manga and while I don’t plan to follow the manga (currently), I’m definitely a fan of the anime already.
