In Gachiakuta, the world is split between the Sphere, a clean upper society that survives by throwing its waste—and people it deems worthless—into the abyss, and the Ground, the harsh world below that’s built entirely from that discarded trash. Objects thrown away with strong emotions can turn into dangerous trash beasts, while some become Jinki, powerful tools or weapons that only certain people can fully use. Those people are called Givers, individuals who can draw out a Jinki’s true power by forming an emotional connection with it rather than just using it. In the Ground, groups like the Cleaners fight trash beasts using Jinki to protect what remains of humanity, proving that even things and people labeled as “garbage” can hold immense value.
