Traveling to a different world where memories can be traded, I became a scavenger specializing in dealing with "memories of haunted houses".
Originally I just wanted to make enough money and then stop, until in the mind of the richest man's daughter,
I saw myself being dismembered and hidden inside the wall of her house.
And she was smiling and asking me: "Do you want to cooperate to find the real murderer?"
Behind him, the entire city's black market of memories began to collapse silently.
