In New York, 1928, the seals between Earth and Hell are breached. Hold on to your rosary as professional exorcists rage against depravity in this iconic series from the creators of Afro Samurai and Trinity Blood. Brandishing sacred weaponry, Sister Rosette and her partner Chrono dutifully serve the Magdalene Order, a divine organization that cleans the streets of demonic filth. Their main target: Aion, an indomitable devil raining apocalyptic horrors upon America. A doozy of a devil himself, Chrono's true powers can only be released at Rosette's command - draining her own life in exchange. Staring mortality straight in the face, this dynamite pair races against time to destroy Aion and restore the balance between good and evil.
