An interesting take on how Japan sees demons and Christianity. In this anime we have two brothers raised in a Japanese temple monastery. One brother is studious, quiet and wants to be a doctor. The other son is rambunctious and seems to be in trouble all the time.
As we get through the first episode we get to see the artist take on demons and
we find out that everyone called the second brother the demon child. Funny thing it turns out he really is a demon child. The son of Satan in fact. Now in western stories he would be the Antichrist but in this one he decides after his adopted father is killed to become an exorcist.
He goes to True Cross Academy, a school to teach many things but mostly to teach exorcists. A fun yet very intense anime. This has some fun twists.
