The suspense horror/dark fantasy story is set in Tokyo, which is haunted by mysterious "ghouls" who are devouring humans. People are gripped by the fear of these ghouls whose identities are masked in mystery. An ordinary college student named Kaneki encounters Rize, a girl who is an avid reader like him, at the café he frequents. Little does he realize that his fate will change overnight.

The ghouls of Anteiku invaded the Aogiri's site in order to rescue Ken Kaneki who is being tortured. Due to provocation, he unleashed greater power enough to defeat Yamori. To become stronger, he decided to join Aogiri and left Anteiku. Ghoul investigators also making their moves by collecting information about the eye-patched ghoul - Ken Kaneki.

An exciting new episode unfolds in Tokyo, just two years after the attack on Anteiku. Countering a resurgence of ghouls, the CCG selects young officer Haise Sasaki to lead an unruly team of humans infused with ghoul powers. Known as the Quinx Squad, they cross the line between humans and ghouls to rid the world of its scariest threat. But no one said it would be easy. The hunt is on!

Kaneki Ken has finally regained memories of his former self, but this once again leaves him at a crossroads in the war between human and ghoul. After donning a pair of glasses to mirror his mentor Arima, Kaneki's new assignment is to manage the interrogation of Eto, the One-Eyed Owl, after she reveals her ghoul nature in a press conference about the publication of her newest book, which she claims will bridge the gap between the two warring sides. Now interred in Cochlea, Eto eagerly awaits the awakening of the "One-Eyed King", but only Kaneki seems to understand what she's really planning. As Aogiri Tree descends on the facility to rescue their leader, Kaneki turns to one of his oldest friends for help in his new secret mission.
