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? Haise Sasaki is no more. In his place, Ken Kaneki has emerged and accepted the role of the One-Eyed King.

He sees a vision of the future where Ghouls and humans can coexist. However, a faction at the CCG wants to prevent that peace by any means necessary, and the inevitable death toll means nothing to them.
