The Bell Rings on a Rainy Night, Awakening from Overclocking

Also known as "The Eye of Light and Dust", a car accident on a rainy night left a young boy with the ability to see the "information dust" left behind in all things: memories, obsessions, and traces of past existence. He met her, and from then on he saw the backside of the world: the forgotten remains, the gatekeeper who burned himself into a lighthouse, the light waiting to be remembered. It's not about killing monsters and upgrading. Once it is seen, it does not really disappear.
