About
Modern Japan. While a peaceful daily life appears to unfold on the surface, a top-secret facility exists behind the scenes to house those deemed "unfit for society" or "dangerous." Its name is the Nationally Designated Isolation Facility, "Cage of Ash." A facility that does not exist in the eyes of the law. Without a trial, those who are suddenly "erased from society" one day are sent here, never to return to the outside world again.
