Daphne (ダフネ) is the Witch of Gluttony.
Daphne has shoulder length gray hair which she has tied into two tails. She has a fair complexion, a small chest, and is delicate. Her body was placed in a diagonal coffin, tightly secured with physical restraints, with her eyes covered very tightly with a black blindfold.
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, and because caring about them wouldn't fill her stomach. She rarely shows emotions, though she did laugh when Subaru told her that he would get rid of the Oousagi. She also likes to give nicknames to people, such as Subarun to Subaru, Dna Dna to Echidna, Met Met to Sekhmet, Ner Ner to Minerva, Mila Mila to Carmilla, and Tyu Tyu to Typhon.
A long time ago, a man was afflicted with an incurable disease, and, as he was afraid of dying, he began using various methods to try and prolong his life. Daphne was one of the many people he used in his experiments, and eventually he succeeded in achieving his goal by using her body. In his joy, he forcibly undid her binds, and when she came to her senses she found herself all alone in the man's castle, suffering from hunger. To satisfy her hunger, she began eating everything in the castle, including things like the throne and the carpets, and resorted to eating what she threw up when necessary. As she was immortal, she couldn't die, however she felt like she was going to die from hunger. Eventually, she somehow began creating Demon Beasts in the castle, which she considered to be illusions at the time, and started to use them as a food source. After a while, her binds broke from the fighting between her and the beasts, allowing her to leave the castle. The Demon Beasts also left and spread across the world.
Authority of Gluttony (暴食の権能 Bōshoku no Ken'nō): Daphne is able to use the Authority of Gluttony.
- Daphne can make people feel extreme hunger by touching or looking at them. Just one eye was enough to force Subaru to experience it, causing him to eat his arm and try to lick his own blood while ignoring everything other than the thought of eating. Despite this, Echidna described Daphne's left eye as "nothing much", stating that she was a terror if she used her right eye or if she "ate" him.
- Daphne's name refers to 41 Daphne, a large asteroid from the asteroid belt. In Greek mythology, Daphne is known as a naiad, a type of female nymph associated with fountains, wells, springs, streams, brooks and other bodies of freshwater.
