Up in the opulent celestial Capital of the Lofty realm, the Spoiled harvest goddess sakuna whiles away her life in luxury, resting on the laurels of her late parents. Below in the lowly realm, a vicious mountain bandit chases a group of desperate humans to the edge of a cliff. A bridge between the two realms appears, and it is there that sakuna crosses paths with the "children of men." in the commotion that follows, the goddess and the waylaid mortals cause a great explosion that earns them the ire of the celestial ruler, lady kamuhitsuki. She exiles them to hinoe island, a mysterious place bordering the Earth and heavens that sakuna's parents once called home, and commands them to reclaim the aptly titled “Isle of demons” from the clutches of a monstrous horde. As the daughter of a Warrior god and harvest goddess, sakuna will rediscover her birthright in this untamed wilderness by weathering the elements, fighting monsters, and cultivating the soil. And by helping their Immortal protector, the humans Banished with her may yet find the reason to live that was stolen from them in the war-torn lowly realm. Together, these unlikely companions must join hands to tame both the soil and the demons of hinoe island.
