Ryan heard out his entire story and a question bubbled up in his mind, "Mr. Tom, the ghost you banished and this ancient ghost of this house are they the same or different?"
"No, they are different. And Tom only." Insisted the former exorcist and ghostbuster.
"Okay…." Agreed with Ryan and asked him how in the world his locket reached there.
The answer was very simple, and Nagisa answered it for him.
"The previous owner must have auctioned his/her house after the auction after the ghost incident, and the former owner of this house must have bought it from there."
"Yes, you are absolutely correct," complimented Tom.
Since he had been around for a while, and with his former profession of an exorcist he must have noted down his weaknesses, Ryan took the chance and asked him about the ancient ghost.
