Witch of Gluttony. Daphne's reason for living is to feel full, causing her to care more about amount more than taste, though because she is bulimic she sometimes throws up what she eats. She created the Demon Beasts to try and get rid of hunger, however she doesn't care if people die because of them, stating that those who try to eat others should be wary of being eaten themselves.
Her body was placed in a diagonal coffin, tightly secured with physical restraints, with her eyes covered very tightly with a black blindfold.
