Gachiakuta

Living in the slums of a wealthy society are a population of “tribefolk,” who are descended from criminals exiled from society. Living amongst the tribefolk is a young boy named Rudo, who detests the upper class’s wastefulness. They often dump anything deemed trash, including criminals, into a massive dump site below the town known as the Abyss. Rudo was told by his foster father that his biological father was dumped into the Abyss for a crime before he was born. One day, after rummaging through a dump site, Rudo returns home to find his foster father Regto killed. Apprehended at the scene, Rudo is immediately charged with murder despite his innocence, due to his status as a tribefolk. Unable to escape his fate, Rudo swears revenge upon the people of the city, and is dumped into the Abyss.

After being dumped into the Abyss, 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 Engine. Engine explains to Rudo that he is in fact not underground, but has fallen to the surface from “Heaven.” After testing him and awakening his power as a “Giver,” Engine invites Rudo to join him as a “Janitor.” Engine explains that the Janitors are an organization of Givers who use the power of unique weapons known as “Jinki” to hunt the beasts which attacked him. Rudo reluctantly accepts Engine’s offer to join the Janitors, so long as it helps accomplish his goal of returning to Heaven and enacting revenge on those who dumped him into the Abyss.
