Sora 2
Arthur has been finding lost things all his life. When he touched an umbrella that had been left in the park, he accidentally "paused the world." A gray-suited curator appeared out of the clouds and explained that reality was just a simulation, and Arthur's ability was a bug in the system. The extra items were simply not being removed from the cache. With a flick of his fingers, the umbrella disappeared, and a note appeared in his pocket: "Don't look for it." Since then, Arthur has stopped finding small items and is now searching for a way out of the simulation.
