It was Yuuki Masamune who called.
"Kid, what are you doing?"
"Having dinner."
"At this time?"
"This is how it is for us bachelors."
Uncle Yuuki on the other end of the phone paused for a moment before finally speaking, "Right, I'm calling you because there's a serious matter to inform you about, regarding the intense ghost stories that happened to the Itakura family that you reported."
Kamiyagawa had travelled in the Hearse Procession's spirit vehicle and rushed to Osaka, saving a young man from the Itakura family named Ayumi Itakura.
Afterward, he deduced that the woman from the box had already started a slaughter amongst the other descendants of the Itakura family in reality.
Thus, he informed Yuuki Masamune about this information.
Planning to dump this troublesome affair onto the official exorcism organization to handle.
Uncle Yuuki calling now likely meant that things had already started to unravel.
