Daphne

Daphne (ダフネ) is the Witch of Gluttony.

Appearance
Daphne has shoulder length ashen hair which she has tied in two tails. Her appearance is that of a 13 or 14 year old child. She is dressed in a pitch-black straitjacket which she wears over her white clothing, that are chained to her coffin. Both of her eyes are completely covered by a blindfold, wrapped to cross over the center of her face, which lends her appearance a much more witch-like aura, as opposed to other Witches of Sin. Despite her eerie and off-putting aura, she can be quite adorable at times.

Daphne herself is chained to a black coffin that resembles the torture device iron maiden, which is most of the time standing vertically. Daphne named the coffin Centipede Coffin. On her command, the coffin's lower part will open up and reveal eight crab-like legs that will move itself and its host anywhere Daphne wishes to go. She stated her coffin operates on her sweat, pee and other bodily waste produced by its host. Subaru described it as a living being, similar to crabs or spiders but more repulsive.

Personality
As the Witch of Gluttony, Daphne's reason for living is to feel full, causing her to care about the amount more than taste. She was also seen repeatedly vomiting out food and eating it again, although she seems to indulge in such acts only when there's no more food left. If that option fails, she will resort to eating objects she can chew, like rugs, curtains, clothes, etc. In an effort to try and get rid of the never ending hunger, she created the Demon Beasts but soon after lost control of them and accidentally released them into the world. Despite the threat the Demon Beasts present, they were created with a positive mindset - to save the world from hunger. Her view on hunger is bizarre and weird, stating that those who try to eat others should be wary of being eaten themselves, therefore she was unable to comprehend Subaru's counterarguments to her theory.

Daphne's speech is described as incoherent and surreal. Talking with her eye to eye is practically impossible for anyone who isn't suffering from extreme hunger, as she does not understand the basic human mindset and values. Her only goal is to save the world and herself from hunger, no matter the cost. Subaru described her mentality as animalistic and not something a person should possess. Her manner of speech is usually cheerful and childish, indicating her age. 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. She regards Gluttony as the most important craving in life, stating a person is unable to live without eating. She rarely shows emotions or the will for basic human functions apart from indulging in her Gluttony.

History
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.

It was claimed that over 400 years ago, Daphne died of starvation in an unnamed desert. Echidna later proceeded to locate and collect her soul, allowing Daphne to manifest in Echidna's castle of dreams.

Abilities
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.

Trivia

 * 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 fresh water.
 * She is said to be able to hold surprisingly large amounts of mana.
 * In the Light Novels, the scene with Daphne uncovering her left eye and using her Authority of Gluttony and forcing Subaru to eat his own hand was omitted.
