Demons and angels co-exist with humanity in a fragile and increasingly volatile world. GHOST agent Robert and his team are sent into the Void, a horrifying realm of the dead in a desperate effort to stop the nightmare dreams becoming a reality and triggering the next apocalypse. Every mission is suicidal, but now with the help of the strange mysterious girl who lives in the Void named Eva Heart, they might just stand a chance...if Eva's own twisted agenda doesn't get them all killed first.
