Tokyo Ghoul

Ken Kaneki, a college student in Tokyo, survives an attack by Rize Kamishiro, a ghoul who feeds on human flesh. After the incident, Ken discovers that he has become part ghoul himself, leaving him caught between his former human life and a new existence that requires him to confront the same hunger as his attacker. As his condition becomes known, he is forced to stay ahead of those pursuing him while trying to understand what he has become.
