Ernst overthrows the existing bureaucracy and names himself Pope, and rises Yukio to the rank of Paladin and head of the Japanese branch. Rin and all the other members of True Cross Academy are armed and given a new edict: kill as many demons as possible. The weapons absorb demon blood for a ritual to open the Gate of Gehenna and destroy Satan for good. Rin is the sacrifice to unlock the gate, while Yukio transforms into a demon himself.
This episode covered a lot of ground. One could almost say the series is now in a hurry to wrap things up. Ernst showed up a couple episodes ago, and we have no idea who he is or what made him so evil; all we know is, he’s a Bad Guy with plans for world domination, and he’s ensnared an extremely naive (and stupid) Yukio with a promise to save Rin by restoring his full humanity. The force of all the sudden change is so great this week it sweeps everyone up before they can even complain.
This episode also sets a firm morality concerning the fundamental role of exorcists. They’re supposed to slay demons, but not all demons. There are good ones, like Kuro the Cait Sith, Izumo’s foxes, and countless demons who protect forests, rivers and the like. In this regard, our protagonists should be on the side of Princess Mononoke. Like humanity, there is an entire spectrum of demonhood stretching from good to bad. What Pope Ernst has ordered upsets the balance of things. He’s bad, and our ragtag group of students – and Rin, if he’s still alive – must stop him.
