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 has been tasked with teaching Qs Squad how to be outstanding Investigators, but his assignment is complicated by the troublesome personalities of his subordinates and his own uncertain grasp of his Ghoul powers. Can he pull this ragtag group together as a team, or will Qs Squad's first assignment be their last?
