In the dimly lit streets of Tokyo lurk terrifying creatures known as "ghouls," who feed on human flesh when darkness falls. To combat these monsters, an organization called the Commission of Counter Ghoul (CCG) was formed. However, identifying ghouls is challenging because they blend in with humans and live among them to make hunting easier. Ken Kaneki, a college student, finds himself entangled in this world when his date turns out to be a ghoul after he bites into her flesh. After being hospitalized, Kaneki discovers that he has transformed into a half-ghoul due to the surgery he underwent. Unable to satisfy his intense hunger for human meat through conventional means, Kaneki is welcomed by friendly ghouls who run a coffee shop to help him adapt to his new life. As he settles in, little does he know that he will become the focal point of a conflict between his new companions and the CCG forces, and that his existence has attracted the attention of all Tokyo's ghouls.
