In a small district in Tokyo, Detective Ishikawa and his investigative team are reviewing the condition of the victims of a mysterious murder. He is quite experienced in this matter, but this is the first time he has seen such large claw marks on a victim.

Ishikawa: chuckles softly upon seeing the claw marks on the victim. "Huh? This isn't the work of a human, but the work of a supernatural monster. It's impossible for a human to make claw marks like these... looks like I need the help of people from the Paranormal Investigator International."
