Fami

"Any human should be capable of abandoning their morality when they're starving. I'll create the right stage for you."

Fami (キガ) is the Famine Devil (の) and a member of the Four Horsemen. She poses as a student at Fourth East High School, where she is a member of the Devil Hunter Club. She was first mentioned in the Public Safety Saga and debuted in the Academy Saga.

Appearance
She appears to be a young woman who wears a high school uniform and a black cap from the devil hunter club. She is tall, has relatively light neck-length hair, and has several moles on her face. Like the other Horsemen, she has ringed eyes. Her ears feature four earrings, two of which are beads on her right and the other two unusually long and resembling scales or possibly Pochita's pull cord.

Personality
Fami has a very mysterious personality, and her face shows little emotion. She seems very good at reading others as she accurately described both Asa's and Denji's characters. While she intends to forcefully drive Asa to murder Denji and turn him into Yoru's weapon, she is very polite to her. Fami also seems to be affectionate towards Yoru, saying she would do anything for her "little sister."

Justice Devil arc
Fami arrived after Yuko was brought to the brink of death by Asa's sword attack. While not revealing her identity, she told Asa that she could bring Yuko back to life and that she would do anything for her sister. Yuko is later revived in gigantic size, while Fami disappears before Denji arrives.

Fami reappears following Yuko's death, along with the rest of the Devil Hunter Club. She later meets Asa again at the Tanashi Aquarium, introducing herself as the Famine Devil and revealing to her that she cannot turn Denji into a weapon until she loses her morality before suddenly disappearing and trapping them both inside.

Abilities
As a devil, Fami possesses all of the standard devil abilities. Another power of hers allows her to heal others, be they humans, or devils, causing the healed person to acquire great strength and size. This ability was used on Yuko after she was injured by Asa Mitaka's weapon.

She can disappear at once and talk to someone telepathically when she is not physically present. She can also snap her fingers and "take Yoru outside", which apparently separates her consciousness from Asa's mind and body, though Asa still retains her power to turn people into weapons, Fami is also capable of manipulating space as she traps Asa and Denji in the aquarium hallway by making it loop infinitely in order to force the former to turn Denji into a weapon. This phenomenon initially causes Denji to assume that it is the work of the Eternity Devil, returned from Hell.

Trivia

 * Fami's name is entirely in katakana (キガ), showcasing no semantic meanings. However her name is a play on the quantity of syllables of the word famine to the amount of mora its Hepburn romanization "Kiga" has.
 * The name "Fami" is only in the English translation of the manga. The Spanish, French, and Portuguese translations use the name "Kiga".
 * Fami's earrings are a reference to his depiction in the Book of Revelation, where he is depicted holding scales.
 * Asa originally speculated that Fami was the Justice Devil, which is a reference to how Famine is sometimes interpreted as the "Lord as a Law-Giver."
 * Both famine and Justice are often represented by scales.
