Chapter 25

Hinami Fueguchi collapses into an emotional breakdown. Losing her composure, Touka Kirishima rushes at Kureo Mado, who blocks her with his quinque and warns that reckless impulse will cost her life. He drives the weapon into her side and needles her, boasting of the pleasure he took in beheading Ryouko Fueguchi and combining her kagune with her husband Asaki's into a single quinque. When Touka threatens him, he sneers at her for being a ghoul. She demands to know why ghouls are denied the right to live when the one thing setting them apart from humans is their diet, and admits she longs to live as humans do, but Mado brushes her off and lines up a killing strike.

In the other fight, Koutarou Amon realizes his quinque is outmatched even though both weapons draw on kagune material. He accuses ghouls of slaughtering the innocent merely to feed and presses Kaneki on what it feels like to carry out such deeds. To Kaneki's astonishment, Amon breaks down weeping over Ippei Kusaba's death, convinced the world is being corrupted by ghouls. Kaneki agrees the world is broken but counters that ghouls, like people, have emotions of their own. Believing he alone can bridge both worlds, he tries to explain that while some ghouls have gone astray, none should be condemned by blanket prejudice, and that the two kinds ought to understand each other better.

When Amon shows not a flicker of agreement, Kaneki's patience snaps and he declares he will force that understanding through combat.

Mado wounds Touka and taunts her with the origin of his quinque, deepening the theme of ghouls being reduced to weapons. Amon weeps over Kusaba and voices his belief that ghouls corrupt the world, while Kaneki argues that ghouls feel and suffer as humans do. The philosophical standoff ends with Kaneki resolving to make Amon understand through a fight.

Titled Kaigan, translated as Epiphany or Enlightenment, this twenty-fifth chapter came out on March 29, 2012, in the third volume. Its ideas about coexistence between ghouls and humans anchor one of the arc's central debates.
