Volume 1 Overview: The year is 2013, in the future city of NO. 6. Raised from the age of two as a top-ranked elite in a city that embodies humanity's ideals, Shion's fate takes a sudden turn on the night of his twelfth birthday, when he meets a boy who calls himself "Nezumi" (Rat). Why did I open that window that night? I could have lived without ever knowing hunger, grief, or war… "Can I find what they call the will to live within the story that is NO. 6?" — Atsuko Asano
