:re Chapter 123

Yoriko browses a shop full of wedding gowns, remarking that one would hang loose on her, when a voice calls her name and she turns. Meanwhile Mutsuki confronts Kaneki at the cafe, revealing that he watched the staged beheading yet never believed Kaneki dead, recalling their past visit to the shop. He begs Kaneki to return, but Kaneki refuses as Touka steps out from behind the counter and locks eyes with Mutsuki. At the Chateau, Urie finds a gift left for Mutsuki and, entering his room, discovers the walls plastered with duplicated photos of Touka and Yoriko, knives driven through each, one buried in Touka's face.

Back at :re, Mutsuki sniffs the air and declares the place ghoul-run, then accuses Kaneki of betraying the squad and the CCG by killing Arima. He slashes Kaneki's cheek and presses the assault with a flurry of knives; Kaneki realizes the blades carry RC suppressants that will lock down his kagune and that Mutsuki came expressly to kill him. A kagune strike hurls Kaneki through the wall of the building.

As Touka calls out to him, Kaneki is impaled from behind by Shinsanpei Aura, a second-generation Quinx who vows he will share his aunt's fate. Touka springs to Kaneki's aid, blocking Mutsuki's kick with her knee and answering with kagune projectiles, mocking him as an ill-mannered customer. Mutsuki evades and closes in, twisting around to seize her throat, only for Touka's kagune to run him through. Staggering upright, he rages that he despises women, then brandishes a photograph and a severed hand bearing an engagement ring, announcing that Yoriko is about to be married.

Mutsuki confronts Kaneki at :re and is refused. Urie discovers Mutsuki's shrine of knife-stabbed photos. Mutsuki attacks with suppressant-coated knives, disabling Kaneki's kagune. Aura, a second-generation Quinx, stabs Kaneki. Touka battles Mutsuki and wounds him, and he reveals a severed hand and news of Yoriko's wedding.
