I am going on holiday for a week, but I'll join once I get back. Until then, Wraith is in charge of running the Purge. They'll probably be the main antagonists of this story.

As for the plot, a new leader called the Pope of Flames has risen among the Purge. Unlike his catholic counterpart, he is a masked figure with no known appearance, who forms a figurehead for the Purge's recruiting campaigns. He seems to have replaced Kami no Kage, although he lacks any form of cambat capability (as far as you know.)
