This is an epic journey from personal survival to saving the world, uncovering the truth layer by layer.
The world is permeated by an invisible "rule system". It is not that ghosts are rampant, but that the logic of reality has been distorted, forming a realm of absolute rules that must be followed or else they will be "erased." The protagonist is not the chosen one, but the "recorder" and "game breaker" who rely on calm observation and logical reasoning to find vitality and truth in the cracks of the rules.
