When forced or forcing themselves to digest such food, their physical condition will deteriorate. If ghouls attempt to eat normal food, they will be struck by a powerful urge to vomit. The structure of their tongues is also different from humans', making other foods taste disgusting and uncomfortable. They are unable to digest any other type of food due to a particular enzyme their bodies produce.

In addition, it was predicted by Kishou Arima that at some stage every human would eventually become a ghoul, though this prediction has yet to be proven correct even after the final chapter.ĭuring the Dragon event, it is theorized that the Ghoul race came to be hundreds of years in the past after an unknown individual first underwent an explosive reproduction of RC cells and experienced a Dragon-like transformation, releasing spores that mutated a number of humans into ghouls through ROS.Ī ghoul can only feed on humans and other ghouls. However, some ghouls went rogue, refusing to adapt to this new lifestyle. As a result of this and the development of synthetic food, ghouls were allowed to co-exist with humans. By using airborne-transmitted diseases like those utilized by Furuta Washuu, the condition known as ROS (an overload of RC cells) can lead to artificial ghoulification.ĭue to their status as predators of humans, ghouls were prosecuted by the CCG before the end of the Dragon War, after which the United Front between humans and ghouls was formed. If certain rare conditions are met, ghouls and humans may even be able to have offspring ( see one-eyed ghoul and half-human), and through a successful kakuhou transplant surgery, an artificial hybrid can be created. They are as close to humans as possible: they normally display the same attributes the same physical appearance and intelligence as a human with the main exception being their inner biology, mentality, and diet. Ghouls ( 喰種 ( グール ), gūru, translates approximately to eater species) are a carnivorous and cannibalistic humanoid species that are only able to feed on the flesh of humans and other ghouls.
