As he embarks on his new dreadful journey, Kaneki clings to his humanity in the evolving bloody conflict between society's new monsters and the government agents who hunt them. Tokyo is haunted by mysterious ghouls who are devouring humans. People are gripped by the fear of these ghouls whose identities are masked in mystery.
