This work is a sci-fi series set in near-future Tokyo, featuring eight boys and girls as the main characters. Endlessly distorted, deep black. "The Realm of Darkness"—that is what people call the place where shadows devour everything and take everything away. And then there are the grotesque beings, akin to symbols of human despair and chaos. They are known as—"Punishment" (imashime). To investigate the "Realm of Darkness" that erodes the human spirit, eight boys and girls are gathered to confront the "Punishment." Amidst the crisis, the fates of the present and the past intricately intertwine. Will they be able to find light within the Realm of Darkness?
