In a future where the world has been ravaged by a nuclear apocalyse, there exists salvation in a domed city named "Romdeau", where humans and their android servants, the autoreivs, live in. Under the implementation of complete management control, it is a paradise where feelings are literally discarded, and the governing council dictates the way of life the citizens should live. But this utopian landscape is soon broken by a series of mystifying murders. Real Mayar, a female inspector from the Citizen Information Bureau, along with her autoreiv partner Iggy, are tasked to solve the murder cases. She is soon attacked by a creature drawn to her which is neither human nor android, and learns about the mysterious phenomena called "Awakening", an event which draws her further into the case...and to the world beyond the limits of Romdeau
