In a world ruled by the "Painless Doctrine," the goddess-like divine race erases all pain, grief, fear, and memories of death—leaving mortals in blissful ignorance, their joy harvested to sustain the gods. Eira, a young winged girl, awakens a forbidden Chaos Force within her after saving a bleeding deer-horned girl. Hunted as a "contaminant," she flees into the Riftlands, where she befriends outcasts—a wolf king, a nine-tailed fox, an immortal phoenix, and a dream butterfly. She gradually learns that Chaos is not destruction, but the power to devour imposed rules and reconnect severed free will. Refusing to be the gods' vessel, Eira becomes the guide who leads all beings to choose truth—even if it means embracing pain—and finally breaks the gentle cage of divine tyranny.
