He could be a trial run, but the way they went about it makes me think he's either a monster, or has some sort of ties in his heritage to monsters.
I mean, a priest just happens to drop enrolment papers in front of a dad whose son just happens to have flunked his exams and dosent have a school to go to. That screams conspiracy to me >.<
If it is confirmed as a 13 ep series i think i'll drop it, since there'll be so much cut from it. This is one of those where they really should take their time and do it right. But i'm betting it will be a 13 e series, like ninomiya was
