In a world where the night is plagued with man-eating monsters called Stained Souls, three sirens warn the people of their arrival. A world where cloaked figures called Exorcists dance through the night, purging the monsters off the streets. In this world, Devin is bullied for his doll-looking features. Little did they know, he could see the monsters even before the sirens calls. He was in his last year of high school when he was transferred to an island to attend a boarding school. A school for Exorcists.
