Tokyo Ghoul Monster Edition, Volume 4 — Sui Ishida

Ghouls live among us, the same as normal people in every way—except for their craving for human flesh. Ken Kaneki is an ordinary college student until a violent encounter turns him into the first half-human half-Ghoul hybrid. Trapped between two worlds, he must survive Ghoul turf wars, learn more about Ghoul society and master his new powers. In this monstrously massive compendium of Tokyo Ghoul volumes 10-12, Ghouls and the CCG alike converge on the laboratory of Dr. Kano, the man who made Ken a half-Ghoul, in search of answers.
