Summary
Orphaned Yuno endures servitude under a cruel stepmother until natural calamities force her to be offered as a sacrifice to the reclusive Ciel family, rumored gods of the mountains. She expects to be used for power, but instead meets Jupiter, the burdened family head whose repressed longings cause disasters and weaken his defenses against demons. Yuno becomes vital to his survival, and as loneliness draws them together, a rising demonic threat endangers their fragile bond and the fate of the world.
