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 is always calm and composed and seems very good at reading others, as she accurately describes both Asa's and Denji's characters. However, her knowledge has limits, as she doesn't seem to be aware that Denji is Chainsaw Man. While she doesn't hesitate to try to force Asa to murder Denji and turn him into Yoru's weapon, she is very polite to her. Fami also seems affectionate towards Yoru, saying she would do anything for her "little sister." Despite being intelligent, she underestimates humans, believing that any person, if forced to, would be willing to abandon their morals, which gets proven wrong.

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.

Current arc
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.

Soon after Asa and the others successfully break free from the Devil's power and Yoru defeats it, Fami is seen standing on top of a building pondering about her failed plan. She then notices Hirofumi Yoshida looking directly at her, smirking, as they both engage in a staredown.

Abilities

 * As a devil, Fami possesses all of the standard devil abilities.
 * Healing: While her powers and their extent are still unclear, she has shown the ability to heal others, be they humans or devils, causing the healed person to gain great strength and size. This ability was used on Yuko after she was injured by Asa Mitaka's weapon.
 * Separating devil from human: Fami also seems to be able to influence the power of devils in some way. She was able to temporarily separate Yoru from Asa. However, Asa still had the power to turn people and objects into weapons.
 * Telepathy: She can communicate with a person without needing to be physically present, even if that person is trapped in another devil's pocket dimension.

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 the Horseman of Famine’s depiction in the Book of Revelation, where he is depicted holding scales.
 * Like with Santa Claus, Fujimoto likely gave Fami numeral facial moles because he finds that the more moles a character has, the better they look.
 * 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.
