To stave off his own inner turmoil, Haise is focused on the difficult task of training his untested charges and meeting the squad goal of surpassing the premier CCG operative, Investigator Arima. And the Quinx Squad not only have to learn to control their Ghoul-like powers, they also have a hell of a lot to prove to the CCG. Many other squads look at the Qs with suspicion or disdain, but Haise and the other Qs are determined to live up to the high expectations placed on them.
But while the Qs struggle to figure themselves out and fit in, the Ghouls of Aogiri Tree are increasing their membership and expanding their influence. Every step the CCG takes towards total Ghoul eradication seems to be blocked by smarter, stronger, better-organized Ghouls. And as the war to save humankind heats up, familiar faces from battles past begin to show up.
