Gachi Akuta follows Rudo, a hot-headed young man living in the slums where the “clean” society throws out its trash—both objects and people. Wrongly accused of murder, he is sentenced to “Abyss Disposal,” a brutal punishment where the condemned are thrown into a wasteland filled with living trash monsters called Jinka. There, he meets Enjin, a mysterious man who reveals that some trash can be awakened into powerful weapons known as Rag Dolls. Harnessing his anger and a pair of cursed gloves, Rudo begins fighting as a Janitor, a warrior who cleanses corrupted trash creatures. As he uncovers dark truths about society, corruption, and his own past, Rudo's journey becomes a battle to redefine what is “trash”—and who gets to decide.
