One day, a couple comes to Reigen office asking for help, the woman says something strange is going on their apartment building. On the other hand, the man thinks everything, and especially Reigen seem sketchy.
Either way, they accept to take Reigen with them and visit the location, on their way, he begins to brag that he might be the best psychic around. After a couple incidents, they finally are inside the building, and indeed, there seems to be a spirit haunting the place.
Of course, Reigen has no power to deal with a spirit, and decides to call Mob. He does not realize that Reigen is a fraud, and simply does his job without making questions, or wondering if his pay is fair.
