Sepher and her annoying "follower"

Heaven, Purgatory, Hell? To these three it doesn't matter they'll kill it. Angels are dickheads, Demons are jackasses, and the undead are just stupid. These three are usually soloists that kill to their own weapons but after a faithful encounter they find themselves as a team. Spencer's a Bitch, Bree is a Jerk, and Kariel is typically ok. All it takes is an abandoned school, an angel, a ghost, two fake FBI agents and their winged pet, a fallen angel, and two angry hunters "guided" by two tricky poltirgiests. If they can figure out what's going on in that damn school maybe they'll find themselves on a whole new level.

Can they find their way out or will they find themselves sewn up tight and ruling it all?
