Gachiakuta

High above the clouds, a floating city thrives on stark inequality. The wealthy indulge in lavish lifestyles while the impoverished struggle to survive, yet both classes share one common practice: discarding their refuse into the endless abyss below. A young boy living within this divided society finds his world shattered when he is framed for a murder he did not commit. His wrongful conviction results in the ultimate sentence—being cast over the edge alongside the very garbage his people so carelessly throw away. Plunged into the desolate surface world beneath the floating town, he discovers a nightmarish landscape formed entirely from humanity's discarded waste. Over time, this massive accumulation of trash has spawned vicious monsters that roam the barren terrain. Stripped of everything and left for dead in what can only be described as hell, the boy refuses to simply fade away. Driven by an unyielding desire for retribution against those who condemned him, he resolves to forge himself into a formidable warrior. To climb back toward the sky and exact vengeance upon his betrayers, he must first survive the deadly horrors born from the ruins of a careless civilization.
