Ga-Rei-Zero

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-toting 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 together.

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 flesh and blood slaughter innocent citizens. In a life-or-death battle that pits sister against sister, survival may be the greatest agony of all.
