Gachiakuta

In a world of stark inequality, the wealthy inhabitants of a floating city live in luxury, discarding their unwanted items and refuse into the abyss below. Rudo, a boy from the slums, is framed for a crime he did not commit and suffers the ultimate punishment: being cast down into the wasteland with the rest of the trash.

He awakens on the treacherous surface, a hellscape where humanity's discarded garbage has mutated into monstrous creatures. To survive and seek vengeance against those who wronged him, Rudo must master his newfound powers and become a Gachiakuta—a warrior who wields the very trash that defines this world.

This anime is a gritty tale of survival, revenge, and challenging a cruel system, exploring themes of injustice, resilience, and the hidden value in what others throw away.
