Chapter 78

Yukinori Shinohara and Iwao Kuroiwa batter the One-Eyed Owl with relentless combinations, though the Kakuja-grade Arata armor is unruly, and Take Hirako doubts the two can keep pace with the creature. The worst happens when a safety failure in Shinohara's suit lets the equipment sink into him, threatening to devour its wearer if the fight drags on.

While Shinohara fights for control, the Owl voices its bleak view of the world: a place steeped in grief and rage where everyone races to kill and dresses up their reasons, the quinque itself a monument to that hypocrisy. No justification for killing truly exists, it declares, before bursting out through a window as investigators scramble to stop it.

Iwao works to peel the armor off Shinohara and calls for medics, thinking back to the Owl's rampage a decade earlier, a battle he missed while hospitalized. Records from that day noted many injuries but no deaths, and the same holds true now. At the command post, Itsuki Marude learns that ninety-eight percent of Aogiri's ghouls are dead and buildings one through eight are taken, but his celebration is cut short by an urgent call: Kishou Arima orders every available unit rerouted to Cochlea in the 23rd Ward, which Aogiri's true force has cracked open.

Atop a distant tower, Tatara, Eto, and their ghouls have punched through to the SS-level cells. Tatara mocks the CCG for swallowing an obvious feint and orders a retreat before Arima can arrive. Watching from afar, Souta asks Nico about the One-Eyed King, and Nico reveals the target was never at the Aogiri stronghold. Donning his mask, Nico exposes himself as a Clown and vows to be the one laughing last.

Diversion (陽動, Yōdō) is the seventy-eighth chapter and the last of volume eight. The title names the entire scheme, and the chapter deepens Yoshimura's nihilism, turns Shinohara's own weapon against him, and quietly introduces the Clowns as a third faction. Arata, Yakumo Oomori, the One-Eyed King, and Kaneki are only referenced.
