In a grimy, post-apocalyptic world where the wealthy live aloft in a gleaming sky-city and the destitute are cast down to a hellish wasteland known as the Pit, a young boy named Rudo is wrongfully exiled after being framed for a murder he did not commit. Surviving in a realm of sentient garbage and monstrous creatures born from discarded human refuse, Rudo discovers he possesses a unique power to turn trash into formidable weapons. Driven by a burning desire for revenge against those who betrayed him, he joins a group of outcasts known as the Cleaners, who risk their lives to protect the weak and eliminate the Trash Beasts that threaten the Pit's fragile society. Blending dark fantasy with visceral action, the series stars Yumiri Hanamori as the voice of Rudo and Katsuyuki Konishi as the voice of the grizzled Cleaner leader, Engi, crafting a gritty tale of survival, justice, and the hidden value in what society has thrown away.
