Somewhere beyond the boundaries of the known world lies a realm of absolute darkness—a place called the Avidya Zone. This vast, consuming void devours everything it touches, stripping away both matter and spirit alike. From within this darkness, twisted entities born of humanity's deepest despair and chaos have taken shape, and they are known as the Imashime. As the Avidya Zone continues to encroach upon the human world, threatening the very essence of people's souls, an expedition is dispatched to investigate its depths. Eight young individuals—Mahmu Yuzuki, Emiru Hazaki, Heito Isaku, Akashi Saginuma, Iwato Namito, Raika Kasumi, Sasame Izuriha, and Minashi Maki—find themselves brought together to confront the looming threat of the Imashime. Standing at the crossroads of a crisis-ridden present and a destiny rooted in the past, their journey into the unknown is only just beginning.
