Rudo survives in the slums of a floating paradise, a scavenger who finds value in the waste discarded by the wealthy. He is anchored by his bond with his foster father, Regto, and the trust of his childhood friend Chiwa, the only light in a bleak world obsessed with disposability. This existence is shattered when Rudo is framed for Regto’s murder and cast off the edge into the Abyss, a hellish wasteland of predatory monsters. Rescued by the enigmatic Enjin, he discovers he is a "Giver" capable of manifesting the spirits of objects as lethal weapons known as Vital Instruments. Now a member of the Cleaners, Rudo must master his newfound power to survive the hulking trash beasts of the Pit. Driven by a fierce sense of injustice, the boy once treated like garbage vows to climb back to the sky to uncover the truth and exact vengeance on those who threw him away.
