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?! Kaneki was mortally wounded in the CCG attack on the Goat stronghold, and in his desperation to see Touka again, he gorges himself on the bodies of the Oggai. The sudden ingestion of this unusual fuel forces Kaneki into a terrible metamorphosis, the result of which poses a stark new threat to Ghouls and humans alike. Will Kaneki's degradation be what finally brings the two sides of this ancient war together?
