In the world of Tokyo Ghoul, sometimes the only way to fight monsters is to become one… 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?! The Qs Squad once again proves its worth by going undercover to collect vital Ghoul information, allowing the CCG finally move forward with a massive eradication campaign. But this strike pushes the Qs to their limits, bringing all their weaknesses to the forefront. And Haise is the hardest hit when his hidden past rushes forth to impact his future!
