A bureau investigator is a CCG staff member posted to the commission's offices. Unlike frontline ghoul investigators, they carry firearms and Q bullets rather than quinque, serving as backup and handling most of the agency's paperwork.
A bureau investigator is an employee stationed at the offices of the Commission of Counter Ghoul. They forgo the quinque used by their frontline counterparts, arming themselves instead with Q bullets and conventional firearms. Their role is essentially support, called in when sheer numbers matter more than individual skill, and they shoulder the bulk of the CCG's clerical work.
Recruits earn the position by completing the Ghoul Countermeasures Training Center, and they likely make up the largest share of the commission's workforce. Graduates enter at Rank 3 and are sent to a ward's branch office somewhere in Tokyo, whereas a ghoul investigator reports to the 1st ward office and the CCG Main Office and travels as duty demands. Despite the difference in equipment, bureau investigators are bound just as tightly by the Ghoul Countermeasures Law.

There are no women on Namek. That isn't an oversight, it's the biology. Why we handed Piccolo the one thing his own species rules out, and why it had to be trap soul....
In Tokyo Ghoul, frontline officers who fight ghouls directly with quinque are called ghoul investigators, distinct from bureau investigators, who serve in a support role armed with firearms and Q bullets.
