The Commission of Counter Ghoul is the only organization fighting the Ghoul menace, and they will use every tool at their disposal to protect humanity from its ultimate predator. Their newest weapon in this hidden war is an experimental procedure that implants human investigators with a Ghoul's Kagune, giving them Ghoul powers and abilities.

But both the procedure and the newly formed Qs Squad are untested. Will they become heroes...or monsters?! Interim Bureau Chief of the CCG Matsuri Washu has gone conveniently missing, and the power vacuum has allowed the devious Furuta to step forward to take control. His erratic behavior concerns some of the investigators, but the special show he puts on for the rank-and-file CCG employees gains him their support, especially when he unveils the final act-executing Haise Sasaki as a traitor!
