The creative team behind the Full Metal Panic! trilogy is back with a nightmare-inducing series about teenage exorcists forced to draw swords against bloodthirsty creatures of unholy origins. Kagura and Yomi may look like ordinary school girls as they walk the streets of Tokyo clad in short skirts and knee-high socks, but they?re the heroes you scream for when monsters creep out of the darkness. These sword-totting sisters are part of an elite counterattack unit that specializes in suppressing outbreaks of supernatural activity. They train together, live together, eat together, and spend their nights disemboweling demons with sacred blades. Tragedy strikes when Yomi is possessed by a dark spirit, and Kagura must choose between raising her weapon against the eerily familiar face of ultimate evil ? or watching her mentor slaughter innocent citizens. In a life or death battle that pits sister against sister, survival may be the greatest agony of all.
