To survive, gouls need to feed on human flesh, so they kill people or find the bodies of suicides. Due to illegal organ transplantation, the main character Ken Kaneki becomes only half a gul, but feeds on human flesh like everyone else. Gul investigators are specially trained professionals working in the Department for Combating Ghouls. Their task is to investigate and calculate ghouls in order to protect the civilian population of Tokyo districts and protect humanity from the threat posed by ghouls. During the investigation, the investigators carefully search the crime scenes in search of traces of the ghoul's stay, after which they identify and neutralize the target. Since investigators are inferior to ghouls in terms of dexterity, endurance and strength in battle, they are forced to use tactical, man-made weapons. Only ghul investigators are allowed to wear a kuinke - the most effective weapon against ghouls, created from their kagune. In addition, sometimes investigators can carry firearms loaded with Q-cartridges.
