Tokyo Ghoul: Root A (2015)

In modern day Tokyo, society lives in fear of Ghouls: mysterious creatures who look exactly like humans-yet hunger insatiably for their flesh. None of this matters to Ken Kaneki, a bookish and ordinary young man, until a dark and violent encounter turns him into the first ever Ghoul-human half breed. Trapped between two worlds, Ken must survive the violent conflicts of warring Ghoul factions, while attempting to learn more about Ghoul society, his newfound powers, and the fine line between man and monster.
