Amid news reports of "Ghoul" attacks nearby, Ken Kaneki points out Rize, a girl he is interested in, to his friend Hide at a local coffee shop. When Kaneki discovers the two share a favorite author, he asks her out. However, their date ends in tragedy!

Kaneki desperately fights the urge to eat human flesh, the only thing that can satisfy his hunger as a ghoul. He meets up with Hide again, joining him on an errand, and is glad for the companionship. But will his declining condition place Hide at risk?

Yoshimura teaches Kaneki more about how to blend in with mankind, and takes in a mother and daughter needing protection. Two ghoul investigators, Mado and Amon, are assigned to the 20th Ward. In response, Toka takes Kaneki out to have a mask made for him.

Kaneki starts receiving self-defense lessons from Yomo. He meets Itori, who runs her own bar, and is friends with Uta and Yomo. Kaneki is befriended by Tsukiyama, a ghoul who knew Rize, who also enjoys reading, and possesses other, more epicurean tastes.
