Two other anime films based on novels by the same author were released: The Empire of Corpses on October 2, 2015 and Genocidal Organ on February 3, 2017.
In the future, after a nuclear cataclysm referred to as the "Maelstrom" and ensuing civil wars that almost wiped out humanity, peace and utopia have finally been achieved.
Beyond country boundaries, society is controlled by the "Admedistration" and its WatchMe medical nanotechnology, devoted to protecting and extending human life, and is governed by a powerful ethic of social welfare and mutual consideration.
In Japan, three young women—Cian Reikado, Miach Mihie, and Tuan Kirie, the protagonist—reject this supposed "utopia" that lacks any true form of personal autonomy, and attempt suicide together, thereby committing the crime of rejecting life itself.
Thirteen years later, Tuan is working as a senior investigator for the World Health Organization, but remains faithful to her ideas and delights in punishing her body.
