Tokyo Ghoul

Reserved student Ken Kaneki lives in an alternate reality where humans and ghouls exist in uncomfortable proximity. Following a date with Rize, Ken is rushed into hospital and he regains consciousness with her transplanted organs inside his body. Unfortunately, Rize was a ghoul and the life-saving surgery has transformed mild-mannered Ken into a human-ghoul hybrid, who will forever be at the mercy of an insatiable hunger for human flesh. Unless he feasts on unsuspecting strangers, Ken will die.
