Ken Kaneki survives a disastrous date only to find that the operation that saved him has made him a human-ghoul hybrid. With his body undergoing horrifying changes, the reserved college student must cling to his humanity amid a bloody conflict between ghouls and the government agents hunting them.
Before the operation, Kaneki preferred books to reports of the flesh-eating creatures hiding among Tokyo's human population. His solitary routine was interrupted when Rize Kamishiro, an attractive woman, asked him out. While walking her home, he discovered that she had lured him into the encounter with sinister intentions. A tragic struggle followed. Kaneki later awoke in a hospital, where he learned that Rize had died and her organs had been transplanted into his body to keep him alive.
