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) which embodies the fear of famine. She is a member of the Four Horsemen. Fami 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
Fami 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 rosy brown colored neck-length hair, and has several moles on her face. Like the other Horsemen, she has piercing, ringed eyes. On a colored manga cover her eyes are shown to be pink. 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, cold, and composed and seems very good at reading others, as she accurately describes both Asa's and Denji's characters. However, her knowledge is limited, as she doesn't seem to know that Denji is Chainsaw Man. Fami doesn't care if someone discovers her true identity and therefore puts little to no effort into her alias. What's more is that she doesn't necessarily seem to be as outwardly malicious as her brethren, even informing Public Safety officials such as Yoshida about more dangerous devils, albeit after being threatened first.

Ironically, she is a massive glutton who orders 30 meals as soon as Yoshida offers to pay for her, showing she is also an opportunist.

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 people, believing that Asa, like most people, would be willing to do anything to survive if forced to, which gets proven wrong.

Despite Fami's affection for Yoru, the War Devil doesn't reciprocate those feelings and describes her as insane and someone Asa should stay away from.

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 would do anything for her little sister. Yuko is promptly revived in gigantic size, and Fami disappears before Denji arrives.

Dating Denji 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 that she cannot turn Denji into a weapon until she loses her morality before suddenly disappearing and trapping the two 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.

Sometime later, Yoshida asks to meet with Fami at a coffee shop. Fami takes the opportunity to order a massive amount of food, as it is Yoshida's treat. Yoshida reveals his knowledge of Fami's identity as the Famine Devil, but she does not care nor tries to hide it. He tells Fami about an urban legend concerning a prophecy of Nostradamus predicting the end of humanity in July 1999, and Public Safety believes that whatever Fami is planning is connected. Yoshida threatens Fami to talk, and she gives him the name and location of the primal devil that just appeared on earth.

Abilities
As a devil, Fami possesses all of the standard devil abilities. 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 fatally injured by Asa Mitaka's weapon.

She also seems to be able to influence the power of devils in some way. She was able to temporarily separate Yoru from Asa, leaving Asa her power to turn people and objects into weapons and communicate with her at a distance despite her being 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 number of syllables of the word famine to the amount of mora the 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.
 * Fami orders large amounts of food. Being the famine devil, this could mean she is always hungry.
 * For unknown reasons, Fami's head is nearly always tilted to her left.
 * In Japanese the word "kiga" has the same homophone as the Japanese word for "penguin." So, in the Japanese language, there was meant to be a double comedic effect of how Denji wanted to see penguins and Kiga appears shortly after, as well as how funny "Kiga-chan" would sound introducing herself with the cute and silly name of "penguin," but being deadly and threatening.
