Cannibalism

Cannibalism is the act or practice of species eating the flesh or internal organs of their fellows in the same species. In the story, scenes of ghouls eating ghouls and humans eating humans would pass. Also the case of one-eyed ghouls that whatever they choose to eat would be considered cannibalism, because they are half-human, half-ghoul and forced to eat either humans or ghouls to survive.

The term usually is used when a ghouls cannibalize other ghouls or for the cannibalism practice that is aimed to strength one's "ghoul blood". Rarely, ghouls may develop another Kagune which is armor-like and become Kakujas. It is thought that ghouls' Rc levels increase after repeated cannibalizing.
