A ghoul investigator (喰種捜査官, gūru sōsakan) is a specially trained professional employed by the Commission of Counter Ghoul. Most are stationed at the CCG Main Office in the 1st ward but many are occasionally granted authority of investigations in one of Tokyo's other wards. They are tasked with the investigation, pacification, and elimination of ghouls to protect the civilians of Japan from any potential harm caused by ghouls. During their investigations, they analyze crime scenes for traces of ghoul perpetrators, expose their identities, incapacitate or neutralize them.
