Living in the slums of a wealthy society are a population of "tribesfolk", who are descended from criminals exiled from society. Living amongst the tribesfolk is a young boy named Rudo, who detests the upper class' wastefulness. They often dump anything deemed trash, including criminals, into a massive dump site below the town known as "The Pit". Rudo was told by his foster father, Regto, that his biological father was dumped into The Pit for a crime before he was born. One day, after rummaging through a dump site, Rudo returns home to find Regto killed. Apprehended at the scene, Rudo is immediately charged with murder despite his innocence, due to his status as a tribesman. Unable to escape his fate, Rudo swears revenge upon the people, and is dumped into The Pit. After being dumped into The Pit, Rudo awakens to find himself disoriented in a foul-smelling, endless landscape of trash. Rudo is then attacked by large beasts made of trash, and fends them off until he is rescued by a man named Enjin. The man explains to Rudo that he is in fact not underground, but has fallen to the surface from "The Sphere". After testing him and awakening his power as a "Giver", Enjin invites Rudo to join him as a "Cleaner". Enjin explains that the Cleaners are an organization of Givers who use the power of unique weapons known as "vital instruments" to hunt the trash beasts which attacked him. Rudo reluctantly accepts Enjin's offer to join the Cleaners, so long as it helps accomplish his goal of returning to The Sphere and enacting revenge on those who dumped him into The Pit. Characters
