Let us live
on this land so arid.
KARAKARA. It is the sound of aridity. It is the sound of dry asphalt and sandy winds. It is the sound of relentless sunshine, as well as the sound of a withering race.
The “Age of Dusk.” It is a time of senescence for the human species, during which hybrids known as the “Others”—those who are human, yet not—exist in great numbers. On the windswept barrens of a land without moisture, a small gathering of people make their living in a world they no longer know. Down a stretch of highway and far from the heart of the town are two such people, Leon and Lucia, who run a small diner. Together with Aisia and newcomers Rebecca and Mari, they lean on each other to survive in this arid land. Those peaceful days come to an end when Leon hears the sound of a telephone, a Relic from the past and is informed that Cullen, a member of the town vigilante corp, is being held hostage. What is it that the kidnappers seek from Leon? Will this lead to an understanding of the disaster that befell the world in the past?
