Ghoul

Still under relentless torment, Kaneki drifts through a series of illusions overseen by a phantom of Rize. He relives his childhood watching his mother wear herself down: with his father long dead, she juggled two jobs to support both Kaneki and her older sister until the strain killed her, leaving him on his own with only Hide for comfort.

To keep Kaneki's fracturing mind intact, Yamori has him count down from a thousand by sevens. Yamori discloses that Dr. Kanou deliberately turned him into a ghoul, then exploits his regeneration to break him further, even driving a centipede into his ear. When that is not enough, Yamori binds and gags Shuu and Haru and orders Kaneki to pick which one lives. Unable to decide, Kaneki offers his own life instead, and an enraged Yamori kills them both. Sinking back into his inner world, Kaneki is consumed by guilt and pictures everyone he has lost or fears losing through his own frailty.

Turning inward, he confronts the truth that life demands compromise, and that his habit of taking pain onto himself rather than sparing others is exactly why his mother suffered. Rize warns him that if he refuses to sacrifice one thing to protect another, the people he loves will die and the blame will be his alone.

Broken down and rebuilt, Kaneki finally accepts himself as a ghoul, undergoing a transformation of both mind and body. He tears free of his restraints, overwhelms Yamori, and pins him down to turn the same torments back on him, then devours Yamori's kagune to draw greater strength.

Yamori reveals that Kanou engineered Kaneki's conversion into a ghoul and kills Shuu and Haru when Kaneki cannot choose between them. Kaneki accepts his ghoul nature and undergoes a decisive transformation, then breaks free, defeats Yamori, and consumes his kagune.

The finale adapts chapters 61 through 66. It marks the first point in the anime where Kaneki's hair takes on its new color.
