Ken Kaneki, a studious college student with a passion for books, encounters a girl named Rize at his regular café. Sharing the same age and interests, they swiftly form a bond. Unbeknownst to Kaneki, Rize is actually a ghoul—a creature that survives by preying on and consuming human flesh. After an incident leads to the transplantation of Rize’s unique organ, known as “the red child,” into Kaneki, he transforms into a ghoul. This change thrusts him into a distorted reality where humans are no longer the dominant species.
