In Tokyo Ghoul, Vol. 6, the story delves deeper into Ken Kaneki’s transformation as he becomes more entrenched in the brutal world of ghouls. After the traumatic events of the previous volume, Kaneki's struggle with his identity intensifies. He’s forced to confront his new, darker nature as a half-ghoul and begins to develop stronger connections with other ghouls, including the eccentric and powerful ghoul, Rize, whose death triggered his transformation. The volume also explores the CCG’s increasing efforts to hunt ghouls, particularly through the introduction of new, dangerous investigators. Kaneki’s relationships with both humans and ghouls continue to evolve, and he faces difficult decisions that force him to question his morality, as the boundary between his old self and his new one grows ever more blurred. The volume ends on a tense note, setting the stage for the escalating conflict between humans and ghouls.
