Chapter 39: Feast

Tsukiyama has held onto the quinque as a keepsake. Kaneki weighs whether Taro's skills could rival a main-office investigator and concludes the scrapper has power but no speed. Tsukiyama, watching, advises him to use his kagune since he is doomed either way. Plotting his escape, Kaneki decides he must first put Taro down, and by applying lessons from his martial arts manual he manages to crack the scrapper's arm.

Kaneki suddenly collapses, weakened, and it is revealed that a special gas has been released to affect those who avoided the poisoned coffee. Because the gas acts slowly, he throws everything into the moment and bares his kakugan. Even so, he grows weaker still, giving Taro the opening to finally kill him.

Seeing that Kaneki is a one-eyed ghoul, Tsukiyama decides his dinner must not be ruined and turns on Taro, ripping him apart. Madam A instead declares that Taro will be the evening's meal. Tsukiyama apologizes to Kaneki and asks him to put the whole affair out of his mind.

Kaneki uses his martial arts training to injure Taro but is undone by a slow-acting gas after surviving the poisoned coffee. Exposing his kakugan reveals him as a one-eyed ghoul.

That revelation makes Tsukiyama switch sides, slaughtering Taro to protect Kaneki, and Madam A repurposes Taro as the feast, ending the banquet.

The chapter resolves the Gourmet's trap and cements Kaneki's status as a rare one-eyed ghoul, the trait that reshapes Tsukiyama's designs on him. Tsukiyama's abrupt apology sets up his uneasy continued presence in Kaneki's life.
